carapace from its end; from the points of junction a pair of short keels 

 run backwards to the lower lateral keels and are united in the rear by a 

 broad bilobed ridge, thus enclosing a concave subquadrate area; the lateral 

 areas between the lateral keels are also concave, and in front those keels 

 are connected by a low vertical ridge. Pedigerous segments 1—3 have trans- 

 verse dorsal crests, and the 4*^ and 5^^ have each a pair of cristiform dorsal 

 teeth. Pleon segments 1 — 4 have paired dorsal, lateral, and ventro-lateral 

 ridges (less prominent in supposed d), the b^^ has the three pairs on its front 

 half, but behind has only a medio-dorsal ridge and a lateral pair ; the telsonic 

 segment has a medio-dorsal ridge in front and a lateral pair. Appendages 

 in general agreement with C. macrop/dhalma (nr. 13), but antenna 1, 2'^'^ 

 joint distinctly longer than 3* , distal joints of peraeopod 1 a little longer. 

 7^'^ joint of peraeopod 2 one-third of the total length of the limb, following 

 peraeopods rather longer and more slender than in C. rtiacropht/ialma, and 

 the uropods longer, the peduncle more than two and a half times the length 

 of the telsonic segment and over twice the length of the subequal rami.

forming an oval broadest in front, the median part shallowly convex, the 

 boundary constituted by a somewhat raised keel, below which the sides are 

 strongly inflexed, with a second longitudinal keel near the lower border. 

 Pedigerous segments 2 — 5 successively narrowed, with lateral angles more or 

 less rounded. Fifth pleon segment the longest, telsonic pentagonal, the two 

 combined rather shorter than peduncle of uropods. First antenna small,
