    Rediagnosis of the Old World Cyprinodont genus Aphanius (1951)
    In:  Beaufortia vol. 1 no. 1, pp. 1-6
    Details
    Publication Date: 2024-01-12
    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.

    Some notes on the taxonomy, the distribution and the ecology of four species of the Amphipod genus Corophium (Crustacea, Malacostraca) (1952)
    In:  Beaufortia vol. 2 no. 21, pp. 1-10
    Details
    Publication Date: 2024-01-12
    Description: Corophium arenarium was first described by CRAWFORD in his excellent review of the entire genus, in 1937. In the description, the author expressed his doubt already whether it might be a distinct species or merely a variety of C. volutator. CRAWFORD\xe2\x80\x99S observations on the variation of the number of spines on antenna II, segment 4 and 5, suggest that it is only a variety.\nCHEVAIS, 1937, does not give a definite opinion, whether he considers the species distinct from each other or not. For biometrical reasons, as well for reasons of variation observed by other authors, he suggests, however, that C. volutator and C. arenarium are only local races of one species.

    Notes on three species of the genus Sacculina (1952)
    In:  Beaufortia vol. 2 no. 18, pp. 1-9
    Details
    Publication Date: 2024-01-12
    Description: One of the specimens dealt with in the present paper has been described in previous papers, in which it appeared under three different names, all of which for different reasons eventually proved to be erroneous. The present identification as Sacculina cordata Shiino at last seems to be definite. The second specimen, as the first from the material collected by the Siboga Expedition, belongs to the species Sacculina papposa V. K. & B., of which up till now the type specimen only was known; the parasite dealt with here is interesting because the excrescences of its external cuticle are of a structure slightly different from that of the corresponding parts in the type; moreover, in this specimen retinacula were found, yielding an additional character for the definition of the species. The remainder of the material dealt with here proved to belong to a new species, characterized in the first place by the peculiar excrescences of the external cuticle.
