 Alcock's figure of this species differs from that given by 

 Bate in having more numerous ventral teeth to the long 

 upward pointing rostrum. The two agree in having the fore- 

 most of the five teeth on the medio-dorsal carina in advance 

 of the eye. In the South African specimen that tooth is over 

 the eye not in advance of it ; and the ventral teeth of the 

 rostrum are ten in number. According to Alcock and Ander- 

 son "the under margin of the rostrum is armed with eleven 

 to thirteen teeth."

 From the other Pandalidae this genus is distinguished by 

 having the wrist of the second peraeopods only bipartite. 

 The first peraeopods are simple. 



For the single South African specimen which Bate assigned 

 to this genus as C. incertiis, he figured and described the palp 

 of the mandible as two-jointed, and in place of a dentate 

 cutting edge represented a sort of stiletto. On each side of 

 the rostrum he gave an orbital tooth, but no antero-lateral 

 tooth below. Also, according to Alcock, the branchial formula 

 which he gives does not conform with that of the type-species, 

 C. gracilipes, at least as represented by the variety anda-
