reaching produced apex of 4*^ joint (no doubt by error regarded as the 3*^). 

 Peraeopod 1, 2"^ joint (without the long slender apical process) as long as 

 rest of limb (the supposed apical process, unique in length, really an acci- 

 dental meeting of 2 long apical setae, Caiman), 5*^ and 7*^ joints subequal, 

 each shorter than the 6"'. Pleopods of d" with apically serrate coupling 

 spines on medial margin of peduncle, 5*^ pair somewhat smaller than the 

 others. Peduncle of uropods subequal to the exopod which is very slightly 

 longer than the apically acute endopod ; the latter in the male has the 

 medial margin fringed above with setae, below with spines. L. 7—8 mm.

Pseudorostral lobes meeting in front of slightly prominent eyelobe, 

 truncate more obliquely in Q than in d, forming a sinus with antero- 

 lateral tooth sharper in the 9 than in the d. Carapace smooth except for 

 longitudinal median keel in 9 which is sometimes anteriorly denticulate be- 

 hind the eyelobe. First pedigerous segment exposed. First five pleon seg- 

 ments with lateral articular processes in the 9. Eye pigmented. First 

 antennae with 3^ joint longer than 2"'^. Peraeopod 1 short, 2^^ joint sub- 

 equal to rest of limb, without apical process or apical setae, 7^^ joint rather 

 shorter than 5^^ or 6^^\ Peduncle of uropods in 9 once and a half, in d 

 nearly twice as long as the telsonic segment. Rami in 9 subequal, more 

 than two-thirds as long as the peduncle, endopod with medial margin serra- 

 ted, carrying 4 spines, and an apical spine: endopod in d less than two- 

 thirds as long as the peduncle, a little shorter than the exopod, with about 

 10 spines on medial margin and an apical spine. L. 9 3-4 mm, 6 4-3 mm.

9 (C. p.j Pseudorostral lobes very short and obtuse ; antero-lateral 

 tooth well marked. Carapace large and almost globular, laterally smooth, 

 dorsal line evenly arched. Pedigerous segment 1 not exposed, side plates of 

 2°^ produced far forwards, 4:^^ and 5*^ not higher or thicker than the slender 

 cylindrical segments of the pleon, which are smooth except for the slight median 

 keel continued from the anterior body. Eyelobe constricted at base, the 

 rounded tumid terminal part provided with 7 corneal lenses, frontal pair very 

 small. Peduncle of uropods rather longer than the subequal rami. Colour 

 whitish, with brownish pink patches chiefly antero-lateral. L. 9 adult 

 3-5 mm. d not known, unless it be C. argus.

d (C. argus). Differs from female by greater size, carapace not glo- 

 bose, antero-lateral tooth more obtuse, eyelobe not constricted at base and 

 carrying 9 lenses, of which the lateral pairs are very small as well as the 

 frontal. Peraeopod 1 (imperfect in 9), 2"^^ joint longer than rest of limb, 

 in which all the joints are rather short. Colour yellowish white. L. about 

 6 mm.
