to C. zuterrupta Reeve in the character of its sculpture 
and marking, but of a different form. Recorded from the 
Philippines. 
M. (Cythara) gracilis Reeve-—Very beautiful, and strikingly 
marked with orange-brown square spots spirally arranged 
across the smooth ribs. The form also is attenuate-fusiform, 
and very graceful. Also a native of the Fiji and Philippine 
Islands. 
M. (Cythara) interrupta Reeve.—Conspicuous for its fusi- 
form shape, somewhat attenuate at both ends, with trans- 
verse interrupted stretched brown lines between the ribs.

rupted linear marking. Of very wide distribution, from 
Mauritius, throughout Polynesia, to the Sandwich Isles.
