Integument highly indurated. Pseudorostrum and eyelobe as in C. 

 persculpta. Carapace strongly sculptured; a carina crossing it immediately 

 behind the frontal lobe and a second at about one-third of its length from 

 the end, the latter notched in the middle, both connected by a median longi- 

 tudinal carina and 2 lateral ridges, dividing middle part of carapace into 

 •1 depressed areas, 2 dorsal, 2 lateral of irregular shape. From anterior 

 transverse carina 2 slight ridges run forward on each side, one ending in 

 front of the antero-lateral tooth, the other behind it at some distance. The 

 median carina behind the second transverse one is flanked by a sub- 

 parallel pair. Pedigerous segments 2 — 4 with 3 longitudinal crests. Pleon 

 missing. Eyelobe having at the apex a few small corneal lenses. Colour 

 uniformly whitish. L. (carapace and pedigerous segments) 2 ram, estimate 

 for total length under 5 mm.

Pseudorostral lobes produced a little in front of the eyelobe, squarely 

 truncate in cJ, a little obliquely in Q; antero-lateral corners nearly on a 

 level with the apices. Carapace strongly sculptured, but without transverse 

 carinae; a median dorsal carina ends in a bluntly raised tooth; on each 

 side a quadrilateral depressed area is bounded by ridges with a tubercle at 

 each corner, the front margin sinuous, the hinder subparallel to that of the 

 carapace, the low^er horizontal ridge produced in front and behind to the 

 edge of the carapace, the upper continued forward to the side of the pseudo- 

 rostrum. Pedigerous segment 1 in 9 showing a little laterally, 2"^^ large 

 with carina ending in a sharp tooth, and side-plates expanded; tooth wanting 

 and plates not expanded in d, median carina continued to end of pleon 

 segment 5, accompanied by lateral carinae on pedigerous segments 4, 5, and 

 first 2 pleon segments, these carinae stronger in d than in 9 . Eyelobe 

 constricted at base, little longer than broad, with about 9 corneal lenses 

 but no pigment. Antenna 1 without trace of accessory flagellum, 3^ joint 

 of peduncle shorter than 2^'^. Antenna 2 of 9 1-jointed. with 3 plumose setae. 

 About 18 spines in spine-row of mandible. Lower lip with apices very 

 iiarrow, incurved, carrying spatulate spines. Maxilla 1 with 2 apical filaments 

 on palp. Maxilliped with about 13 branchial leaves in 9, 17 in d. Maxilli- 

 ped 3, 2^^ joint sharply angled, produced to middle of 4*^^ joint which is 

 also broadly produced. Peraeopod 1, 2"^ joint longer than rest of limb, 

 6*"^ joint not long but longer than the o^^ or 7*^. Pleopods of d differing 

 from those of C. lonyicandata (nr. 3) by absence of process on lateral margin 

 of endopod. Peduncle of uropods scarcely longer than the rami which are 

 subequal in 9 , endopod serrate on distal half of medial margin and armed 

 "with a small pectinate spine, the apex slightly curved upwards and outwards ; 

 endopod in 6 the shorter, strongly fringed like the peduncle with plumose 

 setae. L. 9 6-3 mm, (3 6-2 mm.

Similar to C. elegans (nr. 14) in shape and proportions, but lateral 

 depressed area on carapace less distinctly excavated, with one tubercle instead
