Previous issue date: 1983-11-22 / Foram realizados estudos que evidenciassem ou não, diferenças nos sistemas reprodutor e digestivo de exemplares das espécies de Thaumastus Martens, 1860, capturados em floresta e restingas do Estado do Rio de Janeiro. A terminologia utilizada baseou-se na microanatomia, histologia, anatomia funcional e bibliografia. Pela macroanatonia do sistema reprodutor, as espécies estudadas incluem-se no padrão dos representantes de Bulimulidae pela ausência de apêndices e a pequena variação morfológica externa. Microanatomia e histologia dos sistemas estudados, evidenciaram diferenças que juntamente com os estudos da concha, rádula e mandíbula permitiram identificar e caracterizar Thaumastus (Thaumastus) taunaisii (Férussac, 1822), Thaumastus (Thaumastus) magnificus (Grateloup, 1839) e Thaumastus (Thaumastus) achilles (Pfeiffer, 1852). / Studies were carried out in order to determine the differences in the reproductive and digestive systems of the various species of Thaumastus Martens, 1860, captured in forests and shoals of Rio de Janeiro State. The terminology used here derives from studies based on microanatomy, histology, functional anatomy, as well as from bibliographical references. According to the macroanatomy of their reproductive system, the species which were studied can be classified together which members of the Bulimulidae, due to the absence of appendices and to the fact that there is a little variation in their external morphology. The microanatomy and the histology of the systems which were studied showed differences that together with the studies of the shell, radula and jaw made it possible to identify and to characterize Thaumastus (Thaumastus) taunaisii (Férussac, 1822), Thaumastus (Thaumastus) magnificus (Grateloup, 1839) and Thaumastus (Thaumastus) achilles (Pfeiffer, 1852).

Previous issue date: 1984-08-23 / Estuda a anatomia de Laevapex diaphanus (Haldeman, 1841) comparando-a com Laevapex fuscus (Adams, 1841). L. diaphanus distingue-se de L. fuscus por possuir dente raquidiano com mesocones assimétricos, a vesícula seminal, a próstata e o ovoteste são menores, a pigmentação do manto é menos pronunciada. Laevapex distingue-se claramente dos gêneros sul-americanos por possuir eixo mediano de pigmentação tentacular, complexo peniano sem flagelo, com ultra-pênis desenvolvido e pênis de poro lateral. As interrelações com esses gêneros são discutidas. Pela primeira vez Laevapex é citado para o Brasil. / This study deals mainly with the anatomy fo Laevapex diaphanus (Haldeman, 1841), in comparison with Laevapex fuscus (Adams, 1841). L. diaphanus maybe distinguished from L. fuscus by the asmymmetric central tooth in the radula, smaller seminal vesicle, prostate and ovotestis , less pronounced mantle pigmentation The structure of the penial complex without flagellum, with a well-developed ultra-penis and lateral penis pore, and a conspicuous hollow core of black pigment in'the tentacles, distinguish Laevapex very clearly fron the south America genera. The interrelationships between Laevapex and these genera are discussed. The genus Laevapex is recorded for the first time in Brazil.
