Notes on a sinistral specimen of Nesopupa bisulcata (Jickeli) (Gastropoda Pulmonata: Vertiginidae) from Kenya
Basteria , Volume 57 - Issue 4/6 p. 103- 105
A sinistral shell of Nesopupa bisulcata from near Homa Bay on the eastern shores of Lake Victoria in Kenya is the first such abnormality recorded for the species. It represents the common type of shell with five apertural denticles. The shell is one of a lot of six, so that it obviously represents a population with sinistral shells. The taxonomic implications of this are briefly discussed.
