the last whorl; from these evanescent tubercles faint radials descend to 
the base; the trough of the deeply excavate fasciole is crossed by fine 
erescentic vadial threads. Aperture:—Lip thin, its edge not reflected, 
without internal lyre; sinus wide and shallow; canal straight and 
produced. Length 26 mm., breadth 9 mm. 
Specimens of Plewrotoma tuberculuta Gray, from Bombay and Karachi, 
differ from 7. granobalteus by more prominent sculpture, and especially by 
the beads on the base. According to Melvill’s figure the new species 
resembles P. nellicw, but differs in ‘colour and the larger number of 
peripheral beads.

My figure is from a specimen 17 mm, in length, which Mr. W. L. May

chocolate-brown.
