Barhatia cancellata, sp. no v. 



Shell acuminatel}' ovate, very inequilateral, gaping towards

 brown periostracum, a tuft of bristly hairs appearing posteriorly 

 at the points of contact of the transverse ribs and concentric 

 ridges ; anterior side somewhat truncate ; posterior side produced, 

 roundly acuminate ; dorsal margin straight ; ventral margin 

 anteriorly very oblique, posteriorly rounded ; umboes broad, rather 

 prominent.

Crassatella yjdiata, Sow., var. ohsoleta, var. nov. 



Differing from the typical form in almost totally lacking the 

 coloured rays which are so conspicuous a character of the species ; 

 in the present variety these only appear as indistinct spots and 

 small blotches of a pale rusty red.

Kellia mirahilis, sp. nov. 



Right valve oblong-subquadrate, rather tumid, inequilateral, 

 yellowish white, with a broad bluish white central oblique band 

 extending from the umboes to the ventral margin, sculptured 

 throughout with wavy punctate ridges presenting a curious and 

 beautifully fine, granular appearance ; anterior side rather short, 

 rounded ; posterior side more angularh^ rounded ; ventral margin, 

 straight. 



Long. . . . . II mm. 



Lat. . . . 15-25 ,, 



Habitat — Andaman Islands. 



It is impossible to adequately describe the wonderful sculp- 

 ture of this shell which is so striking in every way and so widely 

 different from any hitherto described species of the genus, that 

 I have considered the single valve represented in the Warneford 

 collection worthy of special notice and description. 



Scintilla citrina, sp. nov. 



Shell oval, translucent, pale lemon colour, concentrically 

 striate with lines of growth, faintly scratched with very fine trans- 

 verse strise ; anterior side rounded ; posterior side slightly acumi- 

 nate below ; lateral margin sloped ; umboes small but prominent.
