forming angles of various sizes, the sides having numerous transverse 

 broader markings of a deeper colour ; posterior side acuminate ; an- 

 terior side rounded ; basal margin posteriorly flexuous ; lunule rather

Shell rather solid, orbicularly ovate, tumid, inequilateral, the sur- 

 face decussated with very close, concentric, elevated laminae, and 

 radiating, very fine, raised ribs, pale ashy-brown; the sides rounded, 

 the posterior one forming an angle with the dorsal margin, which is

This species is sculptured much in the same way as Venus laqueata, 

 Sow. ; but the concentric laminae are very much more numerous, and 

 the radiating ribs more distant and less prominent. In size it is 

 smaller, and in form it is less oblique, and the umbones are not 

 placed so far anteriorly. The specimen described is the only one that 

 has come under my notice, and has been placed by me in the British 

 Museum, together with the other species described in this paper. 



7. Cardium (Ctenocardia) victor, n. sp. (Plate XLII. 

 fig. 9.) 



Shell quadrangularly cordate, ventricose, equilateral, anterior side 

 rounded, posterior side compressed, slightly concave and angulate, 

 whitish, painted with distant irregular zones and blotches of rosy 

 orange ; radiately rihbed, the ribs about 30 in number, narrow and 

 compressed, somewhat broader at the sides, and furnished with erect, 

 compressed, recurved, scale-like spines, the interstices, which are 

 elevated on the anterior side and excavated on the posterior side, 

 are transversely finely imbricate ; umbones prominent, close together, 

 and incurved ; lunule excavated, not very conspicuous, orange-red ; 

 the umbonal ridge strongly marked ; interior white under the beak, 

 golden-yellow towards the ventral margin. 



Long. 12, alt. 15, lat. 12 lines. 



Sab. Mauritius. 



The specimen figured is from the collection of Sir David Barclay. 

 It was taken out of the stomach of a fish called in Mauritius " Capi- 

 taine," hooked at a depth of 60 fathoms off that island.
