 Shell, seen from the side, quadrangular, somewliat higher in 

 front than behind, height equal to more than half the length; ante- 

 rior extremity obliquely rounded, and bearing numerous small 

 teeth, posterior rectangularly truncated, produced abruptly 

 below the middle, tlie produced portion divided into four or five 

 stout teeth, whicli project directly backward ; dorsal margin 

 straight, forming an elevated angle over the hinge-tubercle, 

 ventral straight, curved upwards at the posterior extremity : seen 

 from above, oblong, subhastate, widest behind the middle, twice 

 as long as broad ; anterior extremity obtuse, with two mucronate 

 processes, posterior wide, truncated, with a broad dentated cen- 

 tral projection. Surface irregularly tuberculated and pitted, and 

 having on the lateral aspect of the valves three prominent, com- 

 pressed, flexuous, longitudinal ribs, one of these being coincident 

 with the dorsal margin, and ending abruptly a little in front of 

 the middle ; hinge-tubercles prominent and glistening. Ventral 

 surface quite flat. Length -^ of an inch ("65 millim.). 



Two specimens only of this species were seen. The type 

 specimen, sent to me by M. le Marquis de !Polin, passed out of 

 my possession after being described, and the figures given in 

 ' Les Fonds de la Mer ' are by no means satisfactory. I can 

 scarcely doubt, however, that these Ceylon shells belong to the 

 same species, and that the Mediterranean form referred by me to 

 C. Stimpsoni (Ann. & Mag. Nat. Hist, passim) ought to be re- 

 named as a distinct species. I therefore propose to call it after 

 my friend the Eev. Dr. A. M. Norman, Cythere Normaniana.
