    Notes: Abstract Following injection of newly formed female pupae or adult Drosophila with C 14 -labeled β-alanine, appreciable labeled free β-alanine was retained in the internal organs for at least 24 hr. Ebony retained most, while heterozygotes were intermediate. Part of the β-alanine-2-C-labeled portion of the molecule was bound to the internal organs, especially the ovaries and mature egg follicles. Dissected normal pupal cuticles incorporate β-alanine-1-C as directly related to the degree of tanning. KCN, ethanol, or air exclusion inhibit incorporation. Tan pigment and radioactivity are extractable from the cuticles by hydrazine-ethanol. A β-alanine precursor is uracil. Injected β-alanine immobilizes ebony, but not normal, flies (newly emerged) and inhibits glucose, but not glucose 6-phosphate metabolism. Desiccated ebony adults take up water more readily than normal adults.

    Description: Four female and two male chimpanzees were secured in various positions on a Daisy Decelerator and subjected to forces ranging from 54 to 180 G. It was found that forces in excess of 54 G may rupture the tympanic membranes and cause subepithelial hemorrhages in the middle ear. The majority of cases showed proteinaceous material, with or without cells in the petrous air spaces. When exposed to forces above 119 G, there was engorgement and often rupture of the pericarotid venous plexus. When supine, distortion of both superior and posterior semicircular canals was found. With forces in excess of 54 G, the cupulae of the cristae ampullaris were either elevated or destroyed. The hair processes were also often broken off. The otolithic membranes, especially of the maculae utriculi were also elevated or otherwise distorted and the saccule was often partially collapsed. In several instances, there was an overabundance of a proteinaceous substance in the lumina of the vestibular apparatus and in the cochlear ducts with their associated scalae. In half the cases, the cochlear duct was narrowed by the depression of the vestibular membrane. Although there seems to be considerable individual variation in ability to withstand these forces, neither age, sex nor weight appear to directly influence the results. The possible sources for the materials found both in the air cells and labyrinth are discussed.

    Description: These small structures in nerve axils at the underside of leaves have given food to various theories and have been nonetheless in phytographic and taxonomic neglect almost from the beginning. That was in 1887, when the Swede A.N. Lundstroem published an extensive paper, in which he explained domatia as structures intended to accommodate mites – hence the word acarodomatia – which latter would in turn benefit the plant by cleansing the leaves from fungus spores. Lundstroem arrived at this hypothesis on the strength of ideas current in that time, about the existence of symbiotic relations between ants and plants; it was in the heydays of teleology. A closer investigation left little of the illusions about mutual benefit between ants and plants, but such critical interest was never focused on the supposed relation between mites and plants. Recently I could grow a few domatia-bearing species under acari-free conditions; the plants with their domatia did as well as in the open. Yet it is hard to prove that Lundstroem was wrong, but a combination of the experiment, the wellknown fact that domatia are inhabited by acari as often as not, and the origin of the hypothesis make if very unlikely that mites will creep into domatia for other reasons than a natural preference for shelter in small holes. All other (physiological) explanations are unconvincing, too, and so for the time being an explanation is lacking – provided that such an explanation would be necessary.

    Description: The practice of citing collections made in institutional series by the letters of that series instead of by the collector’s name (e.g. FB 23435 instead of Aquilar & Valderrama FB 23435) led, with the publication of so many Identification Lists, to the dishing out of an alphabet soup that many a botanist or curator of collections may find hard to digest. In itself, the system of collecting in long institutional series is an excellent one, permitting great economy in space when collections are to be cited. The oldest series seems to be the KB-one, dating from about 1870, established by Scheffer, followed early in this century by the BS and FB series, established by Merrill. A good number-stamp may have contributed much to the success and consistency with which the series were maintained for a long time. In other institutes, there has been created what Dr. Ashton characterized as ”a masterpiece of confusion”, the unravelling of which, as can be seen from his paper on ”The numbering of Sarawak Forest Department collections” in this Bulleton on pp. 1432-1435 (1966), requires a good deal of research. The purpose of this paper is only to give a list of abbreviations in use between Thailand and the Solomons, for the guidance of those who compile, and those who use Identification lists. These Lists, products of the work for the Flora Malesiana, serve as documentation as well as being of use for the identification of Malesian duplicates not seen by a taxonomist himself. When compiling and using such a list, three questions are to be considered.
