An abundant shell at Karachi, especially the neigh- 

 bourhood of Manora. We have seen nearly a hundred 

 specimens, differing a little in basal breadth, and length, 

 and also in number of whorls, the colour varying from pale 

 chestnut to dark russet ; and the larger examples are lon- 

 gitudinally streaked or suffused with darker brown. Seila 

 bandorensis Melv., described from Bombay examples, 

 occurs with it, and we shall hope in a succeeding paper to 

 draw up a revised description of this, Mr. Townsend's 

 specimens being dredged, and perfect at the mouth. 



vS. hinduorum is no doubt near dextroversa Ad. and 

 Reeve, but the spiral carinae are all equal, and the colour 

 is chestnut brown. A strong family resemblance charac- 

 terises this section of Cerithiopsis, the majority of species 

 being American.
