 Hab. Camorta (Roepstorff) ; S. Andaman (Roepstorff). 



Var. fusiformis, Nevill, torn. cit. 



" Well distinguished by its produced and fusiform shape ; the 

 whorls increase regularly and are more convex than those of 

 the type form, in which the upper whorls are abruptly and cori- 

 tractedly attenuate, the lower ones increasing rapidly in size, 

 especially the last, which is always very tumid. In var. fusi- 

 formis, on the contrary, it is only a trifle more swollen than the 

 preceding one. More solid and of brighter coloration ; sculpture 

 rather less distinct." (Nevill.) 



Alt. 32-5 (9 whorls), diam. 9 mm. 



Hab. S. Andaman (Roepstorff). 



Yar. perstriatula, Nevill, torn. cit. p. 238. 



"The last two whorls are throughout regularly and evenly, 

 finely spirally striated." 



Hal. Andamans [?] (Stoliczlca).
