Cardium intermedium. This shel], of which we have only casts, is very 

 near in form to Cardita iidermedia of Lamarck ; the hinge, as vve leani 

 from the impression, however, wants the long margint^l tooth, vvhich 

 marks the genns Cardiia. Length i inch, width the same. 



Loc. Baboa Hill. 



Cardium amhiguiim. The furrov/s upon the surface of this cast are 

 deeper than they would be in a cast from the European C. serratum ; 

 which, in the general form of the shell and number of furrows it resem- 

 bles more strongly than it does the C. Icevigatum of the Indian Seas. 

 Length 2 inches 1 line, width 1 inch 10 lines. 



Loc. Baboa Hill. 



Area hjlirida-. Transversely oblong, oblique, longitudinally costated ; 

 costse strongly marked with the lines of growth, — those on the anterior 

 side, furrowed along the middle ; area narrow. Length 1 1 lines, width 

 14 lines. 



Nearly related to the recent A. rhomhea^ but with a narrower area be- 

 tween the beaks, approaching to A. Indica of Linnaeus. 

 Loc. Baboa Hill. 



Pectunculus Pecten. Orbicular, convex, ribbed ; ribs about 30, radi- 

 ating, crenated by the lines of growth ; hinge-line short. Length 10 

 lines, width 1 1 lines. 



Very nesi'ly like P.pectinatus of Lamarck, but with more numerous 

 and more distinctly granulated rays. 



Loc. Baboa Hill. 



Nucula Bahoensis. Transversely oval, convex, smooth ? ; lunette sunk; 

 beaks nearest the anterior side. Length | inch, width 1 inch. 



Nearly resembling N. BowerhankU (Geol. Trans., 2d series., vol. v. 

 136. PI. 8. f. 11.) but not truncated or pointed below the lunette. 

 Loc. Baboa Hill. 



Pecten Icevi-costatus. Short, smooth, radiated ; radii about 20, large, 

 equal to the spaces between them ; ears large; inside furrov^'ed. Length 

 1 inch 4 lines. 



Length a little less than the width, but the ears enter so much into 

 the sides that they confine the beaks into a small angle, and make the 

 form appear more transverse than it really is.

Osirea callifera. (Lam. Hist. Nat, vol. vi. p. 218. Deshayes, Coq.
