    Notes: Implants were made into forelimbs of Triturus viridescens using fresh, frozen and boiled kidney and liver of T. viridescens and R. pipiens. Limbs were recovered at intervals up to 70 days post-implantation.Kidney implants from Wisconsin R. pipiens gave twice as many extensive accessory structures as did Vermont frog kidney. Total induction percentages, however, were similar.Quantitative and qualitative parameters for implant-induction of accessory structures were investigated. The decrease in antigenicity and increased rate of cytolysis of frozen implants resulted in increased similarity between frog and newt kidney in rate and pattern of breakdown and in rates of induction. Modification of rate and duration of the release of the stimulating factor from the implant did not result in induction by liver implants.No evidence was found for any increase in innervation prior to or coincident with blastema formation. Implantation and implant cytolysis may cause hypersensitivity of limb tissues to the normal innervation pattern or trophic stimuli from the implant may act with those from the injured limb tissues to produce growth.The general pattern of host reaction to the implanted material was studied and described.

    Notes: Morphological aspects of lateral line system of Gymnotidae, Mormyridae and Gymnarchidae were studied: “Ordinary” and specialized sense organs were identified and their somatic distribution and their relation to the lateral line nerves established. An attempt was made to classify the specialized sense organs of the lateral line system in these families. The morphological results are discussed in relation to recent physiological data permitting identification of one of the specialized sense organs as a newly recognized sense organ, the electroreceptor.

    Labiopedia, a sex-linked mutant in Tribolium confusum duval (Coleoptera: Tenebrionidae) (1965)

    Notes: The genetics and anatomy of the homoeotic mutant labiopedia (lp) of Tribolium confusum is described. The mutant is the second known among the insects to affect the mouthparts. The two-segmented labial palps of the larva are completely replaced by leg-like appendages resembling the prothoracic legs and exhibiting the apex of the trochanter and all parts distal to the trochanter. The labial palps of the pupa and adult are likewise replaced by legs. The three-segmented palps of the adult are replaced by appendages closely similar to the prothoracic legs in many characters and exhibiting the apex of the coxa and all other parts of a normal walking leg. The legs have never been seen to move although they are supplied with labial nerves and an almost complete, though highly reduced, set of muscles. The labial appendages are invariably leg-like and well-developed, failing to show the range of variability which is commonly observed in homoeotic mutants. The leg-like form of the heteromorphic organ is in striking conformity with the appendicular origin of the palps.The lp gene is recessive and sex-linked, with lethal to semilethal effects. It is the third sex-linked gene discovered in Tribolium confusum and the first sex-linked homoeotic mutant known among the insects. Since the inheritance of lp is entirely in the manner of a sex-linked gene, it most probably is located on the original X chromosome, unless the translocated autosomal portion attached to the Y has become inert.

    The structure of the digital setae of lizards (1965)

    Notes: Light and electron microscope studies of the digital lamellar setae of geckos and anoline lizards demonstrate that the free ends of the setae consist of flattened spatulas of less than 1 μ in width. The anoline setae are simple structures usually less than 30 μ in length and with a single terminal spatula to each seta. In contrast the setae of geckos are complex structures of about 100 μ in length, with numerous branchings, and having many spatulas per seta. The spatulas of Gekko and Aristelliger were smaller (0.2-0.4 μ in width) than the spatulas of Anolis (0.8 μ in width). The electron microscope studies indicate that the scales of lizards appear to be covered with small epidermal spines (1.5 μ long). The setae of anoles and geckos are considered to have evolved independently from these more primitive epidermal spines. It is further suggested that the mechanism that allows the lamellae to adhere to the substratum is a surface phenomenon. The spatulas provide a large surface that is in contact with the substratum and thus produces a large total frictional force. The α layer of the lizard stratum corneum can be readily identified in the lamellae. However, the structure of the β layer is not easily interpreted and there is evidence of a fibrous layer between the Oberhautchen and the α layer in the skin of the outer lamellar surface.

    Notes: The muscles and motor and sensory nerves of the pregenital abdominal segments were described and discussed in relation to the nerves and muscles of the thorax, as described by other workers. Each of the integumental muscles was named and described with regard to its location, function and innervation. Differences among segments of the same sex and between sexes were noted.A description of a longitudinal muscle, named here the hyperneural muscle, was included. The muscle overlies the abdominal portion of the nerve cord and may be derived from the ventral diaphragm. The most notable features of its structure are chiasmata of fibers which occur at points along its length and which show consistent relationships to the nerve cord and median nerve.A previously undescribed organ, located ventrally at the intersegmental fold, having dual innervation and showing stretch receptor function was described.

    The rat submaxillary salivary gland.This investigation was supported in part by Public Health Service Research grants DE 01701, DE 01794 and DE-K3,419, from the National Institute of Dental Research. A correlative study by light and electron microscopy (1965)

    Notes: The rat submaxillary salivary gland has five distinct parenchymal zones.1Acini consist of secretory and myoepithelial cells. An extensive network of canaliculi connect the many cells within an acinus to the main lumen. The fine structure of acinar secretory cells suggests that they are capable of great synthetic capacity; each cell having a large amount of ergastoplasm, many Golgi zones, and a great amount of secretory material. It is proposed that these cells are of the continually secreting type.2Intercalated ducts consist of cuboidal cells and myoepithelium. This segment connects the acini to the main conduit system of the gland. The fine structure of the cuboidal cells indicates that they are essentially nonsecretory.3The granular duct consists of three types of columnar cells; (a) dark narrow cells which contain many free ribosomes but no ergastoplasm or granules, (b) light granular cells which have varying amounts of ergastoplasm and granules, (c) dark granular cells which are full of granules while the other cell constituents including the nucleus, occupy a basal position. It is proposed that these three cells represent different secretory stages of the same cell type. This supports the interpretation that secretion in these cells is not continuous, but cyclic in nature.4The striated duct forms a small portion of the total gland parenchyma and consists of tall columnar cells with extensive infolding of the basal plasma membrane, relatively little ergastoplasm and very few granules. It seems likely that ion and water metabolism is a specialized function of this segment.5The excretory duct consists of three cell types: (a) tall columnar light cells, (b) dark columnar vesiculated cells and (c) small basal cells. The basal infoldings of these cells and the arrangement of many capillaries around these ducts suggests that this segment is primarily concerned with water transport.

    Notes: It was demonstrated that the germinal (surface) epithelium around the mouse ovary consists of simple squamous, cuboidal and columnar arrangements of cells. With the electron microscope it was shown that these cells have the usual cytoplasmic constituents such as the Golgi complex, mitochondria, ergastoplasm, and free ribosomes. Their nuclei are surrounded by a bilamellar envelope with coarse granular masses of nuclear material being distributed along its inner surface. From the surface of these cells extend numerous microprojections which usually are irregular in squamous cells, but are villus-like on the cuboidal and columnar forms. These microvilli appear to be simply extensions of the cell surface and apparently reflect the capacity of mesothelium for such specialization at its free surface. The intercellular boundaries are seen to consist of wavy, downward extensions of the plasma membrane or a complex irregular interdigitation of coarse lateral processes. The latter form is especially prominent between squamous cells. A membrane is present at the basal cell surface. The observations concerning the presence of microprojections and the nature of the intercellular boundaries were discussed in the light of the controversies on these subjects which appear in the early literature. The possible permeability of the germinal epithelium and its functional significance during maturation of the ovary were also discussed.

    Notes: Pre-copulatory behavior of male Aedes involves pursuit, tarsal contact, ventral orientation, and terminalial contact. Copulation itself involves seizure of the female's cerci by the male's claspers, extension of the male's paraprocts, erection of the aedeagus, and ejaculation. The male's ability to copulate is prevented by damaging or removing his seventh abdominal segment. If this segment is left intact, his freshly removed abdomen can copulate with a freshly isolated female's abdomen when their terminalia are rubbed together appropriately. The male's genital apparatus accurately “recognizes” the terminalium of an inseminated female, and forced-copulation cannot be induced. The claws at the ends of the male's claspers are inserted into the bases of the female's cerci. The thumbs of the apical paraprocts of the male fit into a temporary coital cavity within the upper vagina. The hooks of the male's apical paraprocts are inserted into the female's cloacal hollow. The teeth on the distal end of the aedeagus ratchet into the teeth on the dorsal vaginal valve and evert the upper vagina. The posterior ends of the seminal vesicles and accessory glands open and contractions of these organs release seminal material only into the bursa of the female.

    Notes: Recent physiological studies on the crayfish Procambarus clarki (Girard), Astacura, Decapoda, have suggested the existence of certain anomalies between the classical interpretation of the segmentation of the crayfish and the more recently established segmental innervation patterns. An extensive reinvestigation of the skeletal segmentation has been undertaken, based on the dissection of both fresh and fixed specimens of this and two other crayfish species, to decide to what extent misinterpretation of the skeletal structure might provide an explanation of these apparent anomalies.As a result of this attempt to provide a self- consistent analysis of the crayfish skeleton, it has been necessary to conclude that the epimeral plate is tergal rather than pleural in origin, that the basal segment of the thoracic legs contains a subcoxal element, that this subcoxa exists as a free leg segment in the last thoracic legs and that the abdominal pleural folds are in part homologous with the subcoxae of the thorax. On the other hand it has not been necessary to diverge from the classical account of the segmentation, except to recognize the existence of a seventh abdominal segment (segment XXI) posterior to the uropod segment.
