In this paper the authors give an anatomical and histological analysis of the genital duct in mature and immature females of Pomacea canaliculata (Lamarck, 1822). Anatomically, the vagina has an equal dimension in its extension, varying in form and volume, according to the maturation period. In the immaturity, it has a smaller diameter and volume. In the maturity, the vagina increases in volume, having the aspect of a tumescent organ, and in certain specimens shows an albuminous pink thread in its lumen. Histologically, the calcigenic activity of the gland is evidentiated by the presence of an amorphous and basophilic mass, without nuclear material. This material has a fragmented aspect in the vagina lumen that reacts positively in van Kossa's coloured preparations for calcareous salts.

Results from studies with Bulimulidae from Northeast Brazil, with special reference to the State of Pernambuco, are presented. About 14 spp., of Bulimulidae s.s. were collected and represent one of the most diversified families of land snails in this area. From these, Drymaeus rufolineatus (Droüet, 1859) and Simpulopsis corrugata, Guppy, 1866, were recorded for the first time in Northeast Brazil and a new subspecies Drymaeus b. goianensis is described. Data of geografic distribution, ecology and shell morphology for each species are given.

Field observations on a population of Tropidurus melanopleurus confirm conspecificity by detection of courtship behavior. Peculiarities in female and juvenile behavior were observed in this poor known species.

This paper concerns the definition of the caudal fin of nine species of Cichilidae. For this, the caudal fin was analyzed regarding shape and position of the urostyle, parahypural and haemal spine 2 as well as the degree of ossification of the hypuraphophysis, number of caudal rays and distribution on their supporting elements.

Phrynops geofroanus is a carnivorous side-necked turtle. Its feeding behavior is divided in foraging, approach, capture, dilaceration and ingestion, but not necessary all these phases happen. Location of food seems to be visual and recognition olfactory. When food is an agile prey approach is done by pursuing and there is no olfactory recognition.

Notes and comments on the Neotropical genus Leptopyrgota Hendel are presented. The following Brazilian species are described as new: apposita, celeriuscula, accolens, quaerens, ensifera, definienda, cocta, andrei, marci, sarae, juniae, liae, isabelae, gracilenta, flavipes, lenkoi, brevipennis, tibialis, minensis, caelifera, hesterna.

A check-list of the birds of the rio Peixoto de Azevedo, Mato Grosso, Brazil (10º 10' S, 54º 50' W) is presented, based on collections prepared by Werner Bokermann and Emílio Dente during the months of July and August, 1976; June through August, 1977; August of 1978; March, May, June, August and October, 1979; August of 1980 and only sporadically after these dates. Each species account includes the date that specimens were collected, gonad development, weight, color of the soft parts (iris, bill and tarsus), and, when necessary, notes on systematics. Measurements are presented in millimeters and weights in grams, with the mean of the sample expressed between parentheses. Theses data are yet scanty in brazilian ornithological literature.

New data on Brazilian cave fauna are added to previous surveys and the relative abundance and distribution of the cavernicolous taxa is discussed. Terrestrial representatives of several arthropod families and genera are common in both tropical and subtropical Brazilian caves: Endecous and Eidmanacris crickets, Reduviidae heteropterans, Carabidae, Catopinae and Ptilodactylidae beetles, dipterans such as the Chironomidae, Keroplatidae, Phoridae and Drosophilidae, Hydropsychidae trichopterans, Pseudonnanolenidae and Chelodesnidae millipedes, Plato, Ctenus, Loxosceles and Blechroscelis spiders, Pachylinae opilionids, Chernetidae pseudoscorpions and acarians such as the Macrochelidae and Uropodidae. Other taxa are mainly or exclusively tropical Blattelidae, Blattidae and BlaberidaE cockroaches, Histeridae beetles, Noctuoidea moths, social insects as termites and ants, Styloniscidae isopods, Migalomorpha spiders, Amblypigi On the other hand, Psauridae spiders, Goniosoma and Tricommatinae opilionids, Elmidae beetles, and Philosciidae isopods seems to be mainly subtropical. Brazilian aquatic cave fauna seems to be less diversified than the terrestrial one. Siluriform fishes such as pimelodids, trichomycterids and loricariids predominate throughout the country, besides decapod (Macrobrachium shrimps, Potamidae crabs, Aegla anomurans, the latter exclusive of subtropical caves) and amphipod (Spelaeogammarus, in tropical caves, and Hyalella) crustaceans. Insect larvae (e.g. Elmidae coleopterans, Nematocera dipterans, trichopterans) and adults (e.g. Veliidae and Naucoridae heteropterans, Dytiscidae coleopterans), oligochaetes and gastropods such as the Hydrobiidae, are also relatively common. Blechroscelis spiders, Goniosoma opilionids, Zelurus heteropterans, Eidmanacris crickets, Keroplatidae dipterans and Macrobrachium shrimps, among others, live next to the entrance zone in the majority of the caves. But, these animals become troglofiles under certain circunstances (an exceptional input of energy, or the absence of competition with cave-adapted species more efficient).

Five new species of the Genus Psyllobora Chevrolat, 1837 are described and illustrated: P. amazonensis, P. balinti, P. jalapaiensis, P. sicardi and P. veraecrucis.

Four new species of Psyllobora Chevrolat, 1837 (P. batesi, P. borgmeiri. P. gorhami and P. huancayensis) from Neotropical Region are described and illustrated.

A review of the original descriptions and available types of the South American freshwater stingrays Trygon aiereba Müller & Henle, 1841, Trygon strogylopterus Schomburgk, 1843 and Disceus thayeri Garman, 1913 indicates that these three nominal species are synonymous. The senior name, placed in the monotypic genus Paratrygon Duméril, 1865, established for Trygon aiereba, is available and valid. Based on its description, T. aiereba is a freshwater stingray. Therefore, this taxon is not the same as Raja ajereba Walbaum and Raja orbicularis Schneider, both names established for the marine "Aiereba" of Marcgrave, and which preferably should be treated as nomina dubia. Paratrygon does not replace Potamotrygon Garman, 1877 as the type genus, because the family name Potamotrygonidae Garman, 1877 has priority over Paratrygonidade Gill, 1893.
