 p. 6, 7 t. 5 f. 1—5. 



Pseudorostral lobes very short, eyelobe reaching' quite to the tip (over- 

 lying without separating them?); antero-lateral tooth almost spiniform in Q^ 

 less so in c5. Carapace of q slightly compressed, not globose, with dorsal 

 edge almost level, feebly carinate. First pedigerous segment well exposed 

 in Q, very slightly in d, second slightly carinate, sideplates well produced 

 forwards. Pleon segments subcylindrical, with lateral articular processes. 

 Prominent eyelobe provided with numerous corneal lenses, larger in 6 than 

 in Q , frontal pair seemingly very small. Antenna 1 rather long, 3*^ joint 

 longer than 2"^. Peraeopod 1 very long and slender, 2"'^ joint little more 

 than half as long as rest of limb, not apically produced, 7*^ joint nearly half as- 

 long as 2^^. longer than 5*^, shorter than 6*^. Peduncle of uropods longer than 

 the rami, medial margin serrate in Q , setose in d ; endopod in Q three- 

 fourths as long as exopod, with spines on distal half of medial margin, in 

 d only a little shorter than the exopod and fringed with 10 spines. L. g 

 3'1 mm, (S 3-3 mm.

Very near to C. exscnlpta (nr. 13). Pseudorostral lobes apically ob- 

 liquely truncate with shallow emargination, the elongate narrow eyelobe over 

 lying them to the apex ; antero-lateral tooth well marked. Carapace strongly 

 sculptured ; a somewhat sinuous carina crossing the frontal lobe not far from 

 the base of the eyelobe runs out into a prominent tooth on either side,, 

 marking the greatest breadth, its downward continuation meeting a straight 

 horizontal ridge continued far backwards; a little behind the middle of the 

 length of the carapace a second transverse carina on either side of a 

 median notch rises into a laminar tooth with sharp apex bending forward 

 and downward; laterally to this pair of hooks the carina is continued obliquely 

 downwards and forwards on each side to join the longitudinal ridge 

 which separates a dorsal depressed area from a lateral one, forming a tooth 

 at the junction, from which a vertical ridge runs doAvnwards as hind margin 

 of the lateral area; to the rear two successive ridges run down to join the 

 horizontal ridge above mentioned; there is a median dorsal keel, which be- 

 hind the second transverse carina is elevated and undulating, forming three 

 lobes; subparallel with this part there are a pair of longitudinal carinae. 

 Pedigerous segments 3 — 5 have dorso-lateral carinae, segments 4 and 5 

 having also each a median carina. Pleon with median and lateral ridges, 

 the median faint on segments 2 — 4, the lateral peculiarly arranged on segment 

 5 ; a transverse crescentic groove on the telsonic segment. Eyelobe having, 

 at the apex very small corneal lenses, the number undetermined. Peraeopod 

 1 long, slender, 2"'^ joint about two-thirds as long as rest of limb, 7*^ 

 joint subequal to 5"\, about two-thirds as long as 6^^^. Other limbs about 

 as in C. anstralis (nr. 20). Peduncle of uropods little longer than the 

 equal rami, which end acutely without terminal spines, endopod having 

 more than the proximal half of its medial margin serrate, this part ending 

 in a spine, the rest bare. L. 9 with developing marsupium 11-25 mm, d 

 unknown.
