SUMMARY The pharyngobranchial organ in Mugilidae, a special pharyngeal structure assuming particular importance in this family for filtration of food, has been studied. The examination was conducted at a macroscopic, histological and ultrastructural levels, with observations at the scanning and transmission electron microscopes. The pharyngobranchial organ consists of a denticular antero-lateral filtering portion and a gustative postero-medial one. The entire organ is supported by a complex skeletal system moved by an intrinsic muscle system. The filtering and gustatory functions are closely integrated in this organ so as to justify the particular alimentary habits of Mugilidae.

SUMMARY The millipedes were submerged in water at 20°, 30° and 35°C to observe anaerobic ability and changes in oxygen uptake. Survival after submersion was better at the colder temperature (20°C) than at the warmer temperature (35°C). During post-submersion (recovery) at all temperatures an initial overshoot in oxygen uptake was noted. Oxygen debt repayment after different durations of submersion periods did not show any consistency, but it was generally seen that when the duration of the submersion period was increased the percentage of oxygen debt repaid was decreased in relation to temperature and size.

SUMMARY The author, in a critical revision of the species of the genus Periscyphis Gerstaecker, currently listed for Ethiopia, shows that Periscyphis jannonei Arcangeli and Periscyphis hugscotti Barnard are synonymous and that the species pilosus Arcangeli should not be ascribed to the genus Periscyphis but to another genus, yet to be established; he describes two new species Periscyphis erythraeus and Periscyphis abyssinicus, and presents a dichotomic key for the recognition of the Ethiopian species described so far.

SUMMARY The activity of acid phosphatases was tested in thoracic muscles of Musca domestica L. (WHO/IN/Musca domestical/1) at pH 4.8 and at 38°C. p-nitrophenylphosphate (NPP) was used as substrate. The course of the enzymatic reaction in function with the time and in function with the different substrate concentrations was examined. The activity of these enzymes in the course of the adult life of the two sexes was analyzed: this decreases with time being greater in the females up until the 9th day. After this, the males present a greater activity which reaches its maximum point on the 15th day. The decrease in activity for both sexes is greatest within the first 9 days of adult life.
在pH值为4.8、温度为38℃的条件下，测定了家蝇(Musca domestica L.， WHO/ in /Musca domestica /1)胸肌酸性磷酸酶的活性。以对硝基苯基磷酸(NPP)为底物。考察了酶促反应过程随时间的变化和不同底物浓度的变化。这些酶的活性在两性的成年生活过程中进行了分析:随着时间的推移，这种酶的活性在雌性中下降得更大，直到第9天。在此之后，雄性表现出更大的活动，在第15天达到最大值。在成年后的前9天内，男女的活动量下降幅度最大。

SUMMARY The availability of a new S. rostratus (Risso, 1826) specimen (Pisces Selachii Squalidae), the re-examination of two museum collections and a survey of literature on the subject has provided the opportunity to clarify some problems concerning this shark and other species of the genus Somniosus. The main topics investigated were morphometric characters, squamation morphogenesis, distribution of cutaneous sensory organs and modified scales. Morpho-functional problems are discussed, with special reference to hydrodynamic aspects. The little sleeper, S. rostratus, has a typical squaloid morphology. In all ontogenetic stages, a peculiar short keel occurs in the caudal peduncle, above the ventral hypochordal lobe. The function of the keel could be to improve turning ability and/or to act as a stabilizer. The caudal morphology belongs to the squaloid type (THOMSON & SIMANEK, 1977) and differs from that of the strictly benthic species. On this basis we therefore believe that S. rostratus is a benthopelagi...

SUMMARY Fresh waters, in which elvers or juvenile eels have been kept for a long time, attract other elvers or juvenile eels. In fact, it was possible to demonstrate a clear-cut preference for these waters compared to waters where other fishes have been kept. If some elvers or juvenile eels have been kept for few hours in the water (three individuals per litre for 24 hr), the effect persists, but it is less marked. The behaviour seems to depend on species-specific substances present in the mucus or in the catabolic products. Effect of social facilitation occurred in the experiments, as suggested by shorter reaction times at higher concentrations of animals (20 instead of 10). Behavioural differences among elvers and juvenile eels indicate a higher rheotactic response by the former.

SUMMARY The authors present morphological, morphometric and histochemical study of the salivary glands of the Colubridae Leimadophis viridis (Gunther, 1862) (Ophidea). Based on the results, the authors concluded: (i) the acini of supralabial, infralabial and premaxillary glands are formed by mucous and mucoserous cells; Duvernoy's gland by seromucous cells; (ii) mucous cells show neutral and sulphated mucosubstances and sialic acid. Mucoserous cells show a neutral mucosubstance, sialic acid and protein radicals. Seromucous cells of Duvernoy's gland show a neutral mucosub- stance and protein radicals. The acinar area, height of tubule and duct cells, and nuclear volume of acinar, tubule and duct cells were evaluated morphometrically.
