SUMMARY The predatory and feeding behaviour of three Licinus species (Coleoptera Carabidae Licinini), cassideus Dejean, hoffmannseggi Panzer and italicus Puel has been observed in the laboratory by offering the beetles eight species of terrestrial gastropods of the families Zonitidae and Helicidae, and some specimens of the prosobranch Pomatias elegans (Muller). These licinine carabids behave as highly specialized oligophagous predators and are able to crush the shells of the snails by means of a peculiar instinctive behaviour pattern that has been called «shell crushing». During this action sequence the shell is opened along the upper part of the body whorl by slow bites which are made at a suitable angle. The breach stretches on to a part of the second whorl. A remarkable plasticity of this predatory action sequence has been observed in relation to the size of the prey and to the barrier given by a calcareous operculum Pomadas). This behaviour pattern is supported by a specialized head morphology, a com...

SUMMARY Seventy Xenopus laevis Daudin larvae (55 at stage 50 and 15 at stage 52–53, according to NIEUWKOOP & FABER, 1956) were submitted to bilateral ablation of the optic lobes and a study was made on the gradual evolution of the regenerative process from the 10th-90th day after the operation. The results obtained demonstrated that: 1. Regeneration of the optic tectum takes place by means of neural elements originating in the ependymal layer of the mesencephalic body. These cells, after covering the resection surface, multiply actively and, attaching themselves to the internal surface of the primitive pia mater, they migrate dorsally. The formation of a primary tectal lamina can be observed on about the 10th post-operative day. 2. In the early stages of the regenerative process of the optic tectum two factors have been shown to be of fundamental importance, regeneration of the pia mater and the pressure exerted by the rachidian-encephalic fluid. 3. Up to the 10th post-operative day the primary tectal lam...

SUMMARY Variations occur in chromosome number through a gradual increase in originally diploid or polyploid sets, accompained by intra-individual oscillations. In many species or races the hyperdiploid or polyploid sets have B-chromosomes. In some species fissiparity is accompanied by such genomic deviations but so far there is no proof that the two events are necessarily correlated. Numerical variations and fissiparity could propagate due to some reciprocal advantage in certain natural habitats and in the laboratory.

SUMMARY Adult specimens of the hermaphrodite synchronous teleost, Serranus scriba were treated with methyl-thiouracil in order to identify the TSH secreting cells in the adenohypophysis. The thyroid of treated animals becames goitrous with hypertrophy of the follicles, which became lined with columnar epithelium. In the adenohypophysis the PAS and TP cells of the rostro-ventral cords accumulated their secretion. The basophils of peripheral cords of the gland and those distributed along the ramification of the neurohypophysis in the adenohypophysis were not affected by this treatment. Morphological changes of the thyroid gland during reproduction were also studied when an increase in the number of thyroid follicles was observed. During this period they were lined with a columnar epithelium. These changes are in correlation with the number of basophil cells of the adenohypophysis.

SUMMARY Experiments with the anophthalmic phreatic fish Phreatichthys andruzzii Vinciguerra from Somalia revealed its sensibility to various monochromatic lights, particularly to blue light (480 nm). The anophthalmic condition is accompanied by a total lack of optic nerves and, in comparison to closely related visual species, a highly reduced encephalon particularly in the zone of the optic lobes. Though the site sensitive to luminous energy has not yet been identified, it can be hypothesized that this is located in the central nervous system.

SUMMARY Spontaneous orientation in T-mazes and at the exits of simple straight corridors were measured in the centipede Lithobius forficatus L. (Myria- poda) and in white mice (Mus musculus L.); the mice were trained by different learning-programmes in a double-T-maze and their spontaneous tendencies were analysed in relation to learning. In Lithobius spontaneous alternation could be demonstrated as the dominant factor in maze-behaviour. In the mice, although descended from one inbred-strain, no general tendency was found, but single individuals demonstrated very fixed types of orientation either as bias or alternation.

SUMMARY Following previous work on the three-dimensional morphology of the somites and developing spinal ganglia, sclerotomal differentiation and the first phase of vertebral development were studied by typing the somitic cellular territories using L.M. and T.E.M. for the analysis of 30 chick embryos (from the 51st hour to the 5th day of incubation). Two distinct territories were identified in the ventro-medial portion of the somite: the undifferentiated somitic mesoderm, loose, with polymorphous cells, located in the cranial half of the somite; the sclerotome, dense, with smaller and ovoidal cells, located in the caudal half of the somite and with a trend to extend in a ventro-medial and caudal direction. Moreover, it was possible to reconstruct the mechanism of the formation of the vertebral body, after the fusion, around the notochord, of homologous sclerotomes, situated from the beginning of their differentiation at a more caudal level with respect to the myotomes and spinal nerves.

SUMMARY The effect of castration and those of replacement therapy with testosterone propionate and estradiol-17β on the interrenal gland and the pars distalis were studied in the male frog, Rana cyanophlyctis Schneider (Amphibia Ranidae). Fifteen days after castration there was a significant increase in the interrenal cell and nuclear diameters and an increase in G-6-PDH and Δ5-3β-HSDH activity in the interrenal gland and changes in these parameters were more pronounced 1 month after castration. The b2 cells in the pars distalis showed a slight degranulation, 15 days after castration and an extensive degranulation, vacuolization and a significant increase in nuclear and cellular area, 1 month after castration. The administration of testosterone or estradiol to the castrates caused the normalization of castration-induced changes in the interrenals as well as in b2 cells. These results suggest that, castration leads to hypertrophy of the interrenals and gonadotrops and treatment of the castrates with androg...
