in II. textrina, B. some specimens of which in my possession are 

 strongly keeled, whilst in others this character is nearly obsolete. 

 Whatever may be thought however of my uniting such dissimilar 

 shells as some of the above, better grounds exist for the union of some 

 which now follow.

which is I think merely a large depressed variety of H. castra of 

 fifteen mills, 



S. capitium, B. Tributary Mehals of Katak. 



II. hariola, B, Pegu. 



I agree with Mr. W. T. Blanford in being unable to find any dif- 

 ference between the Katak shell and the keeled variety of H. hariola 

 from Pegu, save a trifling superiority of size in the former.

Of these shells, the two first are perhaps the least defined, and the 

 whole have a tendency to pass into each other. II. ligulata is the 

 well marked depressed form found in Bengal and II. hullata, H. of 

 only nineteen mills, in diameter, I have from Mhow. I shall now 

 describe a few novelties which have lately occurred to me.

Corpore elongato, lsevi, ante et pone eleganter rotundato, colore 

 fusco, minutissime flavo maculato, subter albescente. Pede transversim 

 rugoso, totius corporis longitudinis, sed vix ad quartam partem latitu- 

 dinis attingente. Tentaculis quatuor ; binis superioribus fuscis, ocu- 

 liferis ; inferioribus minus elongatis quamquam robustis, et papillam 

 retractilem, sensu acutissimo prseditam, subter gerentibus.
