only that in 9 , 2^^ with carina forming a more or less slender tooth, curving 

 a little forward (Caiman), the other segments with a carina, which is continued 

 along front part of the pleon, which has the usual articulations. Eyelobe 

 a little longer than broad, with about 9 corneal lenses (Caiman). 2 rather 

 long but small and 2 large but indistinct (Zimmer). Antenna 1, 3^ 

 joint longer than 2°*^. Antenna 2 9 2-jointed. Peraeopod 1, 2^^ joint 

 longer than rest of limb. Peduncle of uropods shorter than endopod which is 

 shorter than exopod (Zimmer), subequal to the subequal rami (Caiman in 

 text, but endopod shorter than exopod in fig.) L. 9 almost 5 mm, (Zimmer)^ 

 9 4*2 mm, d 4-1(5 mm. (Caiman).

Very like C. bistriata but with the 2 pairs of oblique ridges on the 

 carapace here much more prominent, and a third pair starting from a pair 

 of prominent tubercles outside the frontal lobe and running nearly vertically 

 downwards to join a prolongation of the anterior oblique ridge which runs 

 horizontally forwards to the anterior lower edge of the carapace; tooth at 

 end of median carina serrated behind, carina of 2^^ pedigerous segment 

 sinuous, with front angle blunt and hinder one overhanging the third segment; 

 continuance of median carina here faintly marked, but 4*^ and 5*^ pedigerous- 

 segments and first three of pleon laterally carinate. Peraeopod 1 with 2"*^ 

 joint longer in relation to rest of limb, uropods a little stouter. L. 9 4 mm, 

 d 4 mm.

No pseudorostral lobes meeting in front of the eye, or separated 

 from the carapace even by a suture, antero-lateral tooth subacute, well advanced. 

 Carapace not inflated. Five pedigerous segments distinct. Eye composed 

 of numerous lenses. Maxilliped 3 with 2^^ joint unusually short, 3^ longer 

 than broad, presence of exopod in female doubtful. Uropods with one- 

 jointed endopod.

Integument much indurated, finely facetted, pitted and reticulate. Cara- 

 pace with short rounded keels behind each antero-lateral tooth, a central carina 

 from end to end, raised behind the eye and there presenting a forward- 

 pointing tooth, this flanked by a pair of depressions with a pair of tubercular ele- 

 vations. Pedigerous segment 1 short strap-shaped, 2°^ with outstanding side-plates 

 extended forwards over hind margin of the carapace, 3*^ and 4^^ with similar 

 side-plates extending backwards, 2"^ to 5"^ with median carina, the b^'^ and the 

 first 5 segments of the pleon having also on each side 3 strongly marked 

 carinae. The telsonic segment is produced triangularly between the bases of
