The present species, considerably allied to the Vo- 
luta Hebrasa, figured in a former number of the pre¬ 
sent work, is a native of the Indian seas, and is sub¬ 
ject to considerable variety as to the form and pro¬ 
portions of the shell, some specimens being very ven- 
tricose, and furnished with greatly prominent and 
pointed processes round the base, while others are of 
a more slender form, with very slightly projecting 
processes. Its general colour is pale or yellow-fer¬ 
ruginous, with dusky or rufous-brown variegations.
