Sôbre Auris bilabiata melanostoma (Moricand, 1836) (Gastropoda, Pulmonata, Bulimulidae)

Abstract

O autor redescreve Auris bilabiata melanostoma (Moricand), utilizando exemplares vivos colecionados no Estado do Rio. Além do estudo da genitália, câmara paleal e rádula, analisa variações das conchas de várias proveniências. Chama a atenção para a necessidade de estudos comparativos das partes moles para uma conclusão definitiva, sôbre a validade das duas subespécies (bilabiata s. st. e melanostoma).<br>In the present paper, Auris bilabiata melanostoma (Moricand, 1836), is described based on alive specimens from Estado do Rio de Janeiro, Brazil. Genital organs, pallial chamber and radula are described, as well as variations of the shells from several localities. The author emphasizes the importance of the study of soft parts to come to a definitive conclusion about the validity of the two sub-species (bilabiata s.st. and melanostoma)

Comparative morphology of Astraea latispina (Philippi, 1844) and Astraea olfersii (Philippi, 1846) (Mollusca, Gastropoda, Turbinidae)

“…Radulae were prepared based on Jurberg (1964); they were too thick to be prepared on permanent slides, so were kept in glycerol. They were then dissected and drawn under a WILD M5 stereoscopic magnifying glass with camera lucida connected, and again under a WILD M20 microscope with camera lucida connected.…”

Recharacterization of Synapterpes (S.) hanleyi (Pfeiffer) (Mollusca, Gastropoda, Stylommatophora, Subulinidae)

“…The radula and jaw have been prepared according to JURBERG'S (1964) technique. Anatomic exam of soft parts whose samples have been captured alive was done with technique described in SALGADO et al (1995).…”
