 the spire ; outer lip dilated, thickened, sometimes digitated, 

 running up all or part of the spire, with a sinus near the 

 anterior canal ; inner lip smooth, spread over part of the body 

 whorl and of the spire. The Eed Sea and the Indian Ocean

 rous whorls. — Obs. The pretty little shells thus described are 

 found in seas of tropical climates. They are distinguished from 

 other genera of the family by their lenticular form and the orbi- 

 cular callosity of the under surface. Pig. 357, E. vestiaria.
