Description: Compared with their New World relatives of the subfamily Cyprinodontinae, the Old World Cyprinodonts are but little known. However, some interesting accounts on Turkish species, discovered by Kosswig, S\xc3\xb6zer and Aksiray, have recently been published. Besides the species known, several new forms and species are described.\nWhile compiling an account on these fishes suitable for the home aquarium (Hoedeman & Bronner, 1950\xe2\x80\x941951), we felt some characters need reexamination, not only of Aphanius, but also of the North African genus Tellia which is said to differ from Aphanius only in the absence of ventral fins.

Description: Voorjaar 1949 ontving ik een kleine collectie levende vissen uit Suriname (Nederlands Guiana), door een zeeman verzameld in een poel nabij Paramaribo. Helaas is de juiste vindplaats niet nader aangegeven, dan enige kilometers ten zuiden van de hoofdstad.\nOnmiddellijk na ontvangst werden de vissen, die hier het onderwerp van bespreking zijn, in een groot gezelschapsaquarium (150 X 60 X 50 cm. hoog) ondergebracht, dat reeds werd bevolkt door verscheidene Nannostomini, Hasemania marginata, Rivulus cylindraceus, Acanthophthalmus kuhli, Dermogenus pusillus en Nannacara anomala en N. taenia.

Description: The increased importance which the European red mite (Paratetranychus pilosus (Can. et Fanz.)) (= Metatetranychus ulmi (Koch)) has assumed in recent years has led to an intensive study of its biology and natural history.\nIn the course of these investigations many workers, and in particular those in Nova Scotia (vide Lord, 1949), have become convinced that this pest can be controlled, on apple trees at least, by natural means and that some of the most active agents in its eradication are the representatives of that group of predaceous mites which Vitzthum (1941) placed in the subfamily Phytoseiinae Ber\'lese, 1916 1). As the late Dr. A. C. Oudemans of Arnhem included many if not most of these species in the genus Typhlodromus as he conceived it, this paper is in essence a revision of that genus.\nPresumably because of their small size and limited distribution, which is largely contingent upon readily available populations of their hosts, little attention has been paid to these predators from either the ecological or taxonomic point of view. A cursory survey of the literature pertaining to the predaceous relationship which exists between the Phytoseiinae herein to be discussed and the tetranychid mites may serve as an appraisal of this economically significant group of mites. Koch (1839) in describing what now appears to be a typhlodromid, viz., Gamasus vepallidus, made no reference to its possible predaceous habits. Scheuten (1857) thought that the eriophyids which he found associated in numbers with his Typhlodromus pyri were its offspring. Berlese (1882-1898), however, had a better understanding of these relationships and was able to state in his redescription of G. vepallidus as Seius (Seiulus) vepallidus (K.) that it was a predator of small acari as well as being a mycophage. His countryman, Ribaga (1902), writing of the

Description: In Flora Malesiana Bulletin No 8, 197-231, appeared a report on the changes in the international rules of botanical nomenclature made by the 7th Int. Bot. Congress at Stockholm (1950). Dr D.P. Rogers and Dr G.W. Martin, both members of the ad hoc Committee found some inaccuracies regarding the nomenclature of Fungi. They write: \xe2\x80\x9dThe multigraphed report of the Special Committee for Fungi contained numerous errors, which, because copies were furnished us very late, could not be corrected before distribution\xe2\x80\x9d. They are in favour of the following corrections: Rec. VIII. First sentence; after \xe2\x80\x9d-phyta\xe2\x80\x9d insert \xe2\x80\x9d(for Fungi, -mycota)\xe2\x80\x9d.

Description: During a visit to the Fiji Islands, of about three weeks in March, 1949, through the kind help of Mr. Harold Gatty at Suva I had the opportunity to make trips to various coral reefs. On one of these trips, on March 18, to the reef of Tomberua, a small island to the south east of the large island Viti Levu, I collected an extensive material of various species of the genus Montipora. Among this material there is one colony of Montipora monasteriata (Forsk.), apparently the first to be reported from the Pacific region, as Crossland (1941, p. 35) states: "It is remarkable that the species, which is not uncommon in the Red Sea, has not appeared in any collection outside this area except in Gravier\'s from the Gulf of Aden." Forsk\xc3\xa5l\'s (1775) short description of his Madrepora monasteriata does not give any details about the growth form of the species. Milne Edwards (1860) ranges the species in the group characterized by "polypier subdendro\xc3\xafde ou en forme de touffe rameuse \xc3\xa0 branches digitiformes". Probably Klunzinger (1879) was influenced by Milne Edwards\'s data when he identified a branched form as Montipora monasteriata. After examination of some of Forsk\xc3\xa5l\'s specimens, von Marenzeller (1907) concluded that Klunzinger\'s Montipora tuberculosa belongs to M. monasteriata (Forsk.), whilst Klunzinger\'s M. monasteriata is another species of the genus. Crossland (1941) arrives at the same conclusion; as this author gives an elaborate account of the history concerning the species, I have noted here the most salient details only. According to Crossland the work by Bernard (1897) is not helpful and is best ignored (meaning, of course, as far as concerns the data in connexion with the specific status of M. monasteriata). However this may be, it must not be overlooked that Bernard (1. c, p. 137), although

Description: I. Introduction.\nWhen using here the name Hydrocorallia for a group of corals, it is not intended to regard this group as a recognized systematic unit. Since Moseley (1880) placed the Stylasteridae with the Milleporidae in the Hydrocorallinae, a separate sub-order of the Hydroids, it has been sufficiently pointed out that the families Milleporidae and Stylasteridae have little in common, and that their respective relations are with Hydroids of systematically different groups. Broch (1914) maintains that the family Milleporidae traces its origin to that of the Corynidae, whilst in his opinion the family Stylasteridae is a highly specialized group that has been derived from the Bougainvilliidae.\nStechow (1923) came to the same conclusion, he also placed the Milleporidae next to the Corynidae, and regarded the Stylasteridae as related to the Hydractiniidae (classified by other investigators as the subfamily Hydractiniinae of the Bougainvilliidae). Broch (1924) divides the suborder Athecatae of the Hydroida into three sections, the Simplicia, the Capitata, and the Filifera; the Capitata embrace the Corynidae, the Milleporidae, and a number of other families, the Filifera are divided into the Bougainvilliidae, the Stylasteridae, and some other families. According to Hickson & England (1905) \xce\xa1\xe2\x80\xa2 1) the Milleporidae have very little in common with the Stylasteridae : "It appears to us that to express more accurately the relations of the old group Hydrocorallinae, Millepora should be placed in an order Milleporina situated in our system next to the Hydromedusae, whilst the family Stylasteridae should be placed in an order Stylasterina situated near the Trachymedusae". Some years before publication of the opinion quoted above, Hickson had already expressed his views in a similar manner (cf.

Description: In September and October 1950, Mr. C. Swaneveld, of Zierikzee, and Mr. Jac. Viergever, of Serooskerke, collected some rich samples of Copepods, found alive in the branchial sac of certain species of Tunicates. The greater part of the Tunicates belonged to the Ascidian-species Ascidiella aspersa (O. F. M\xc3\xbcller.) The peculiar little commensal lives in the branchial cavity, often in considerable numbers, with their posterior antenna fixed to the body wall of the Ascidian. The species of the genus Notodelphys stand lowest in the scale of species adapted to this curious mode of life : I observed them moving quickly through the water outside the Tunicate, in a jumping way. Especially when the water contains little oxygen, the animals leave their host through the ingestion opening. They do not swim for longer than a few seconds, then settling again on some object, often the outer wall of the Ascidian.
