352 MESSRS. MBLTILL AND STANDEN ON [June 18, 



The name originally propounded is antedated by P. minima 

 Phil., from the Peruvian coast. 



Phasianella vaeiegata Lam. 



M.C. Generally, from 3 to 7 fathoms, mud. 



Var. nivosa Eeeve (sp.). 

 M.C. Charbar. Ormara Bay. 



I. Karachi. 

 Usually found from 3 to 7 fathoms, sand and mud. Young 

 shells abound on dredged algae. 



Turbo corokatus Gmel. 



I. Karachi. On rocks at half-tide. 



Several interesting embryonic examples occurred, all distinctly 

 and prominently angled at the periphery. 



Turbo intercostalis Menke (=elegans Phil.). 



I. Karachi, on rocks at low tide. Bombay (Abercrombie). 



Turbo radiatus Gmel. 



P.G. On coral-reefs that were uncovered at low tide. 



M.C On rocks at low water. 



The form T. chemnitzianus Reeve (sp.J occurs at I., Karachi, 

 the three transverse spiny ridges on the body-whorl being charac- 

 teristic. T. ticaonicus Reeve, a species common farther east, has, 

 we think on insufficient data, also been recorded from Karachi. 



ASTRALIUM STELLATUM Gmel. 



I. Bombay (Abercrombie). 



Leptothtra filipera Desh. 

 M.C. Charbar beach. 



Leptothyra l^ta Montr. 



I. Lat. 18° 58' N., long. 71° 45' E. 



This may possibly be an undescribed species near the New 

 Caledonian L. Iceta, being more finely striate. It is of a fine 

 uniform pink colour externally. 



Leptothyra pilula Dunker. 



I. Karachi. 



Another species may likewise occur, a specimen not quite 

 referable to either of the preceding species having been recently, 

 forwarded from the Persian Gulf. This may possibly be identical 

 with L. yemenensis Melv., from Aden (Ann. Nat. Hist. ser. 7, 

 vol. i. p. 201, pi. xii. fig. 7).
