On the Geology of CutcJi. 



[Oct. 



This belongs to the same family of Venus as V. Corhis, and V. puer- 

 pera, and is scarcely distinguishable from F. puerpera^ ^. (Lam. Hist. 

 Nat. vol. V. 585.) 



Loc. Soomrow. 



Venus cancellata. Obovate, approaching orbicular, gibbose, ornamented 

 with erect concentric laminae, and many longitudinal striae ; lunette 

 wide, pointed, convex ; beaks nearest the anterior extremity. Length 

 1| inch, width 1 inch 1] lines. 



This resembles the last, except that it is rounder, with thinner 

 laminae, which are not cut into round grains. 



Loc. Soomrow and Kotra. 



Venus non-scrtpta. Tranversely oval, convex, smooth, concentrical- 

 ly undulated ; lunette elongated, pointed, concave ; beaks nearer the 

 anterior extremity. Length 1 inch 4 lines, width If inch. 



A smooth and thin shell, with little of the aspect of a Venus. 



Loc. Soomrow. 



Pullastra ? virgata. Transversely oval, elongated, decorated with 

 smooth concentric ridges ; beaks nearest the anterior extremity. Length 

 13 lines, width 1 inch 7 lines. 



Several recent species of Pullastra are like this^ but no described one 

 appears to be identical with it. 



Loc. Soomrow. 



Cardita intermedia, (Lam. Hist. Nat., vol. v. part 1. 23. Brocchi, vol. 



ii. 520. t. 12, f. 15.) ? This strongly resembles several species of Veneri- 

 cardia, Lam. 

 Loc. Soomrow. 



Cardium triforme. Orbicular, ventrinose, longitudinally striated ; an- 

 terior side covered with round granules formed by decussating striae ; 

 the posterior side crossed by oblique sets of reflected ridges. Length 

 and width 1 inch 4 lines. 



Somewhat resembling the recent Cai^dium ceolicum. 



Loc. Soomrow. 



Area radiaia. Transversely elongated, oblique, rather convex, radi- 

 ated ; radii elevated, furrowed; beaks almost close, nearest the anterior 

 side. 



Length, 7 lines, width 1 inch. 

 Loc. Soomrow. 



Area tortaosa ? Linn. This is only a fragment, and what there is, 

 seems to differ from the recent Area tortaosa in the degree of curvature, 

 Loc. S0omrow.
