Hab. Ceylon (Sowerby) ; Gulf of Martaban, in 67 fath. 

 (' Investigator '). 



Only two young examples were obtained by the ' In^ 

 vestigator,' but the record of another locality is interesting. 

 They consist of ten normal and three nuclear whorls, the 

 latter being globose, smooth, and glossy. At this age, before 

 the last whorl is formed, the shell is fusiform and the 

 columella almost straight. The ground-colour is wbite, 

 variegated with numerous undulating, somewhat zigzag, 

 brown flames. The last whorl is obliquely grooved upon the 

 lower or anterior part.

 figs. 10, 11 ; Reeve, Conch. Icon. vol. vi. pi. xviii. fig. 48. 



Hab. Off south coast of Ceylon, 34 fath. ; also off Coro- 

 mandel coast, 41 fath. 



A small, but apparently adult, shell from the latter locality 

 is destitute of colour-marking, and only 27 mm. in length. 



Rostellaria Powisii, Petit. 

 Rostellaria Powisii, Petit, Mag. de Zool. 1842, pi. liii. 



Hab. China (Petit and others) ; Gulf of Martaban, in 67 

 fath. (' Investigator'). 



This species, which is figured in the monographs by 

 Sowerby, Reeve, Kiener, Kuster, and Tryon, appears to have 

 hitherto been recorded from China only. Its occurrence in 

 the Indian Ocean is therefore of some interest. 



Xenophora (Haliphcebus) Solaris (Linn.). 



Hab. Off Ganjam coast, in 28-30 fath. ('Investigator'); 

 Coromandel and Nicobars (Chemnitz) ; Malacca (Cuming). 



Xenophora pallidula, Reeve. 



Hab. Off Andaman Islands^ in 185 fath., and off Tavancore 

 coast in 360 fath. (' Investigator ') ; Japan (Reeve, &c.)
