tion, should be uniform purplish-red, which accords better with the 

 colour of Reeve's figure and agrees perfectly with the Cumingian 

 specimen.

Reeve's figure in the Conch. Icon, does not bear much likeness to 

 Sbwerby's figure in the Thes. Conch., but the %^^tQ^t's, oi Spondylus 

 vary so much that, without an examination of the types, one scarcely 

 dares to consider them as being distinct species. There are three 

 specimens in the National Collection similar to Reeve's figure, except 

 that two of them are of regular growth, not distorted. I refer to the 

 V-shaped sinus shown in figure. There is no record as to where 

 Sowerby's type is now, but he refers to specimens in the British Museum.

 Museum, 1857, p. 152. 



Hab. : Bay of Panama (Cuming) ; Mazatlan (Carpenter). 



This species is very close to S. limbatus as figured by Reeve, and 

 may possibly prove to be the same species. The specimens of calcifer 

 in the British Museum appear to be of a darker purple-red colour 

 than limbatus^ and shew more prominently the fine longitudinal 

 striae between the principal ridges. Old shells are generally very 

 worn and bored by various organisms; the young shells have long 

 spathulate spines, and are variously coloured, red, purple, and yellow. 



69. — S. exilis Sowerby. Proc. Mai. Soc, 1895, vol. i., p. 280, figured. 



Hab. : Karachi. 



There are other specimens in the British Museum that I take to 

 be the same species; they are from Jeddah, Red Sea.
