 Ind. I, 1883, p. 153, pi. 37, figs. 3-3 h (shell). 



Shell very similar to C. bensoni, but the shell is thicker, and 

 the last whorl descends near the aperture.

 Z^Hab. Panchet Hill, W. of Eaniganj, Bengal (W. T. B.). 

 God win- Austen suggests that specimens from Eajmahal, Sikrigali, 

 and Patna in Bengal, referred by Nevill in his ' Hand-list ' to 

 A. ovata, may be the same as the Panchet shell.

Shell openly perforate, conoidly depressed, thin, smooth,

A variety larger and with a lower spire occurs at Champanir, 

 near Broach. A shell measures 16xl3|x7 mm.; others are

 which cover a great part of the spire, sometimes nearly the whole,
