Abstract

The anatomy of Cochlespira elongata, a new species from continental slope of São Paulo coast, Brazil, is described. This analysis shows some interesting characters in the foregut, with rhynchodeal walls muscular and free from the haemocoel and insertion of venom gland in mid region of the esophagus; in the osphradium, with bilobed right filaments; and in the penis, with a complex arrangement of structures in the tip. A complementary description of Cochlespira radiata (Dall, 1889a) from Florida, USA, is also given, for a better comparison between both species.
