Besides 6'. tubicauda, Pfeffer (I.e.), the only other species of this 

 genus is C. algoensc (Stebbing) (1875, Ann. Mag. Nat. Hist. (4) 15, 

 p. 186, pi. 15 A, figs. 3, 3). The latter was described from a 

 specimen -^ inch in length, which appears to be immature, judging 

 from the shape and size of the posterior peraeon segments and the 

 uropods ; also the circular foramen on the telsonic apex is incom- 

 plete and not directed dorsally. Although both the species 

 described below are ' very common at the Cape, the smallest 

 specimens I have yet come across are -]. inch in length and cannot be 

 correlated with G. algocnse. Until therefore further and adult 

 specimens of C. algoensc are obtained from Algoa Bay (if the 

 original specimen did in reality come from that locality, on which 

 point there is a little doubt), the name algoense cannot be applied to 

 either of the present species. 



From C. tubicauda, Pfeffer, as described by Hodgson (I.e. p. 31) 

 and figured by him (Crust, of the " Southern Cross," pi. 33, fig. 2), 

 both the Cape species are abundantly distinct. Thus C. tubicauda 

 has small eyes, both rami of the uropods are lanceolate, not oval, 

 the outer ramus of 1st pleopod is a little longer than inner, no 

 mention is made of the 2nd peraeopod being much more slender 

 than the other peraeopods, nor of the pectinate spines on apex of 

 5th joint of 7th peraeopod, no mention is made in the description
