Comments. According to Cossmann & Pissarro (1909), the specimen illustrated on their pl. 2, figs 23–24 displays a biconic shape with spiny costae delineating a developed shoulder and looks more like a species of Volutospina than a species of Volutopupa Dall, 1890 (type species: Voluta cithara Lamarck, 1803 by original designation). We designate here this specimen as the lectotype of V. noetlingi . Vredenburg (1923) regarded Volutospina intercrenata Cossmann & Pissarro, 1909 as a junior synonym of V. noetlingi , considering that the specimens used to describe V. intercrenata represent juvenile specimens of V. noetlingi . However, the figured material of V. intercrenata does not display spiny costae delineating a developed shoulder, as observed in juvenile specimens of Volutospina species (e.g. the type species). Thus, these specimens do not belong to Volutospina and are not juveniles of V. noetlingi . In the Lakhra Dome, we have not found specimens of V. noetlingi , but a juvenile specimen of A. (V.) noetlingi from Jhirak has been illustrated by Iqbal (1972) under the erroneous name Lyria cossmanni . As in other juvenile specimens of Volutospina species, it has a biconic shape with spiny costae delineating a developed shoulder.
