Recaracterização do subgênero Toltecia Pilsbry com descrição da conquiliomorfologia e anatomia dos sistemas excretor e reprodutor de Punctum (Toltecia) Pilsbryi (Scott), n.comb. (Gastropoda, Stylommatophora, Punctidae) 104
Fonseca,Álvaro Luís Müller da; Thomé,José Willibaldo.
Conchomorphological and anatomic characteristics of species from Punctum (Toltecia) are presented and discussed. The brief recharacterization about the conchomorphology and internal anatomy of Toltecia with related species from this subgenus is presented. The data from this species are compared with other related species from Punctidae, Helicodiscidae and Charopidae. Punctum (Toltecia) pilsbryi, n.comb. is redescribed and its shells features was analyzed by SEM (Scanning Electron Microscope) and commented, as well as the shells dimensions; the anatomy of the excretory and reproductive systems are described too. The anatomic characteristics, mainly from excretory system, characterize Punctum (Toltecia) pilsbryi, n.comb. like Punctidae.

Conquiliomorfologia de Tamayoa (Tamayops) banghaasi (Thiele) (Gastropoda, Systrophiidae) 104
Monteiro,Daniele Pedrosa; Santos,Sônia Barbosa dos.
Thirty shells of Tamayoa (Tamayops) banghaasi (Thiele, 1927) from Ilha Grande, Rio de Janeiro, were analyzed with a stereomicroscop showing the following characteristics: discoid shell, without macrosculptures; ovate-lunate aperture without teeth. Thin, sharp and not-reflected lip; umbilicus with 1/5 of the shell's diameter; impressed suture, total whorls from 4 to 5.5; protoconch with 1.5 to 2 whorls; yellowish-amber, translucent and glossy periostracum. The morphology of the shells were discussed, as well as the shell's dimensions. The conchomorphological patterns are important for systematic studies of mollusks and this work presents data that can be used in future studies about the family.
