Allied to Plcurotoma acidigemmata, Smith, which has also been 

 recorded from, the Andamans ' ; it is, however, broader at the peri- 

 phery, more sharply turreted, and possesses a much longer canal ; 

 the reflexed peristome in the region of the sinus and the expansion 

 of the columella also easily distinguish it from that species. 



Drillia fraga, sp. no v. 



Shell elongateh' fusiform, deep reddish brown ; remaining 

 whorls 7, rather flat, sculptured with regular closely set rows of 

 small white tubercles and bearing a single, infra-sutural row of 

 coarser tubercles between which and the remaining smaller rows 

 there is a broad but shallow groove ; sutures impressed ; aperture 

 obliquely ovate ; canal short.

In man}^ respects resembling Drillia digitalis, Reeve, from the 

 Philippines ; it is, however, separable from that species by its more 

 acutely fusiform shape and flatter whorls ; the rows of tubercles are 

 also placed further apart and at more regular intervals. 



Drillia sikcsi , sp. nov. 



Shell solid, imperforate, acuminately fusiform, chalky white, 

 painted with abroad, pale brown, infra-peripheral band ; whorls 10, 

 the upper much eroded, the lower bearing a row of coarse tubercles 

 at the periphery ; columella descending abruptly, solid, white ;
