Closely resembling C. hercbnani (nr. 7), but carapace still smoother, 

 dorsal keel simple, feebler, peraeopod 1 much longer, the apically produced 

 2°*^ joint about thi-ee-fourths as long as rest of limb, 5*^ half and 7* three- 

 fourths as long as 6*^, iu peraeopod 5 the 4*^ joint only two-thirds as long 

 as the 5*^; peduncle of uropods a little longer than the exopod, which is 

 slightly longer than the endopod; the latter with 14 spines on medial margiu 

 of d, 6 on upper part of that margin m Q. L. 9 5'3 mm, c? 4*2 mm.

Fseudorostrum truncate, eyelobe reaching quite to the tip ; antero-lateral 

 tooth subacute. Carapace almost smooth in d, in 9 with median keel 

 anteriorly between 2 shallow depressions, followed by feebler double keel 

 starting from a shallow pit. Pedigerous segment 1 exposed in adult 9 . 

 Pleou segments subcyliudiical with lateral articular processes. Eyelobe rather 

 prominent, not longer than broad, corneal lenses indistiuctly defined in 9, 

 large and conspicuous in d. Antenna 1, 1^* joint longer than 2°<^ and thu'd 

 combined, 2"^^ a little shorter than 3^, flagellum 2-joLQted. Antenna 2 of 

 9 2-jointed. Peraeopod 1 not elongate, 2^^*^ joint as long as rest of limb, 

 apically produced into a short pointed process as in C. hornelli, 5*^, 6*^, 

 and 7^''' joints subequal, each in 9 little longer than the 4*'^, but more ex- 

 tended in d. Peraeopod 2 with 5"^ joint little more than half as long as 

 the 4*^ to which it is subequal in the following limbs. Peduncle of uropod 

 as long as the subequal rami, which have acute apices without terminal 

 spines, endopod iu 9 with some 6 spiuules along middle of medial margin, 

 in d rather shorter than exopod, fringed with about 23 spinules decreasing 

 in size successively and leaving bare the last third of the margin. L. 9 

 4-4 mm, d 4'3 mm.

Pseudorostral lobes with apices subobtuse, meeting for a short distance in 

 front of the hardly visible eyelobe (eyelobe running quite to tip of pseudo- 

 rostrum, CalmanJ. Carapace described as smooth, destitute of ridges, yet 

 keeled above, and with a short feeble keel running back from the antero- 

 lateral tooth (Thomson fig., Caiman text). Only the last 4 pedigerous seg- 

 ments exposed behind the carapace (l^* exposed at the sides in adult 9, 

 Caiman). A dorsal keel and slight lateral keels traversing the pleon, the 

 segments of which have lateral notches behind and interlocking knobs in 

 front. Eye not made out (with corneal facets, Caiman). Antenna 1, 1^* joint 

 much larger than 2°^ and 3^ combined, 2"^ notably larger than 3^ (2'^'^ and 

 3d equal, Caiman). Antenna 2 of 9 2-jointed. Maxilla 1, the palp ending 

 in 2 long filaments. Maxilliped 3 with apical process of 2^1'^ joint not quite
