SUMMARY Homing pigeons were supplied with a radar target and followed from the launch point in the open sea by ship's radar. The target does not alter the pigeon's orientation behaviour and allows bearings to be noted beyond the limits of binocular visibility.

SUMMARY The morphology of the egg of the stick-insect Bacillus atticus caprai Nascetti & Bullini (Insecta Cheleutoptera Bacillidae), the Italian member of the parthenogenetic B. atticus complex, was observed with the scanning electron microscope (SEM). A structural organization common to all the Cheleutoptera so far investigated at the SEM level is described. Peculiar and diagnostic characters, concerning mainly the sculpturing of the capsule and the morphology of the operculum, were found, which differentiate B. atticus caprai from the other Bacillinae so far studied, B. rossius (Rossi) and Clonopsis gallica (Charp.). A summary of the main differences between the eggs of these three species clearly shows that B. atticus caprai is more related to B. rossius than to C. gallica. A comparison of the egg of B. atticus caprai with those of the other parthenogenetic members of this complex, as well as with the more closely related bisexual species, is expected to clarify both the taxonomic status and the phylog...

SUMMARY A preliminary experiment is referred on sexual odours discrimination by the Poeciliid fish Poecilia reticulata. The males are significantly attracted by the water in which conspecific females were kept. The females, on the contrary, have not shown any remarkable attraction for the water in which conspecific males have been kept.

SUMMARY Aspects of the breeding biology of anurans have been used as generic criteria in a number of families and, in some instances, species may not be adequately classified without knowledge of their breeding biology. Terrestrial breeding has been used as justification for recognizing advanced genera or species, however, there is little available evidence that this mode of reproduction is either derived or advanced. It is becoming increasingly apparent that some species may have phylogenetic affinities which are independent of their present continental distribution. The possibility exists that terrestrial breeding may have been well established in early anurans and that it is maintained in varying diverse genera of most anuran families. Common ancestry would be a reasonable explanation for the evolution of terrestrial development in so many genera. Genetic selection involving physiological, embryological, and behavioural parameters of terrestrial breeders must surely be more involved than could be adequ...

SUMMARY In five successive experiments, two groups of pigeons which had the same homing experience were transported to the release point by different routes, which were initially opposite in direction or very divergent. In all experiments the orientation of the two pigeon groups was significantly different, as the birds showed a strong tendency to choose a direction opposite to that of the first part of their outward journey.

SUMMARY The structure of the genital duct and accessory glands of the male reproductive system in Drosophila melanogaster was studied by means of phase-contrast and polarized-light microscopes, their ultrastructure being investigated with the electron microscope. Reproductive systems from adult virgins of the Varese wild strain were used as basic material. The results were compared systematically with those from reproductive system of insects of various ages, of insects examined at different times during and after mating and of sterile mutant strains. The most original results relate to: i. the presence of a striated muscle layer whose organization in the individual portions of the reproductive system appears closely related to individual functional activities. Of particular interest is the presence of sphincteric valves between the unpaired deferent duct and the anterior ejaculatory duct. ii. The presence of an unpaired portion connecting the paired vasa deferentia. iii. The peculiar junctions of the acc...

SUMMARY Literature on African Anura is being accumulated. The absence, or limited availability, in Africa of some relevant literature is pointed out. Problems in discovering the existence of some references, in establishing the relevance of some of these, in obtaining accurate bibliographic details, and in acquiring copies, are discussed. Increase in the amount of literature and in the number of African journals is discussed in relation to the effectiveness of abstracting journals such as Zoological Record and Science Citation Index. Problems of synonymy and/or authorship revealed by accumulated literature are illustrated by Xenopus and X. laevis Daudin, Tomopterna, and B. garmani Meek. Availability is related to validity of descriptions and copyright. Production of facsimiles, redescription with illustrations, planned scanning of aquarium/terrarium journal indices, and contribution to current bibliographies is suggested.

SUMMARY Young Bufa bufo larvae (Rossi's stage V to VII), were thyroidectomized by means of a single dose of I131 (20 μC). Starting on the 37th day after radioactive iodine treatment, these larvae were given a daily injection of 0.3 I.U. of pure ovine prolactin (Richter) for 14 days. As compared to untreated larvae, prolactin-treated ones underwent a statistically significant (P < 0.001) higher loss in body weight during their last week of life; they exhibited a less marked degranulation of both the acidophilic cells that are regarded as producing a prolactin-like hormone, and of the thyrotropic cells. The possibility of some direct inhibitory effect being exerted by prolactin on the pituitary cells in correlation with the incomplete development of the hypothalamo-hypophysial axis, due to thyroidectomy, is discussed. In the integument, exogenous prolactin seems to have enhanced the differences brought about by thyroidectomy with respect to normal larvae (i.e. further gland rudiment reduction and more unifo...
采用单剂量I131 (20 μC)对幼年Bufa bufo幼虫(Rossi’s V ~ VII期)进行甲状腺切除。从放射性碘处理后第37天开始，每天注射0.3 iu的纯绵羊催乳素(Richter)，连续14天。与未处理的幼虫相比，催乳素处理的幼虫在生命的最后一周体重损失有统计学意义(P < 0.001);他们表现出较不明显的嗜酸细胞(被认为产生催乳素样激素)和促甲状腺细胞的脱颗粒。本文讨论了催乳素对垂体细胞的直接抑制作用与甲状腺切除术引起的下丘脑-垂体轴发育不全有关的可能性。在被膜中，外源性催乳素似乎增强了甲状腺切除术后与正常幼虫的差异(即腺体进一步减少和更均匀的分布)。
