Paulson's Oedipus dentirostris , as Nobili has pointed out, is a 

 synonym of this species. Borradaile gives a full list of references. 

 C. superba agrees with C graminea in the absence of the hepa- 

 tic spine of the carapace, in the stout form of the third maxilliped 

 and in the possession of a series of small teeth at the distal end of 

 the carpus of the second peraeopod. The principal differences are 

 the following : — 



(i) The ultimate segment of the third maxilliped (text-fig. 98) 



is expanded at the base; the 

 inner margin is sinuous, convex 

 proximally and concave distalty. 

 The segment is only twice as long 

 as broad and is little if at all 

 longer than the penultimate. 



(ii) The carpus of the first 

 peraeopod is scarcely longer than 

 the merus and its breadth at the 

 distal end is little less than that 

 of the merus. 



(iii) The merus of the second 

 peraeopod (text-fig. 99a) is pro- 

 vided with a series of 4 to 6 1 

 small teeth on the superior part 

 of its distal margin and the tooth 

 at the outer distal angle of the 

 lower border is large and trian- 

 gular. There is a series of 7 to 

 10 small teeth x on the upper part 

 of the distal border of the carpus, 

 palm is usually little less than 3 

 to 2 - 8 times as long as the fingers. 

 The form of "the dactylus (text-fig. 996) is entirely different. The 

 outer margin is straight and abruptly angulate in the middle, while

The chela is less swollen ; the

 are less numerous.
