 p. 341,364 t. 34 f. 25— 29. 



Pseudorostral lobes short, truncate. Carapace about half the whole 

 length of the body, dorsal line behind the very small eyelobe convex, 

 flanked by pair of dorso-lateral ridges curving towards it near the end. Pleon 

 segments stout, slightly depressed, telsonic segment hexagonal, broader than 

 long. Maxilliped 3 with well developed exopod, 2^^'^ joint of endopod as long 

 as next 3 joints combined. 4*^1 greatly expanded, less than twice as long 

 as broad, longer than 3 following joints combined. Peraeopod 1, 3'^ joint 

 with medial margin produced into a large thin triangular tooth. Peraeopod 2, 

 7*^ joint rather stout, shorter than f>^^ and 6*'^ joints combined. Uropods 

 remarkably broad and flattened, peduncle less than twice as long as the 

 telsonic segment, the broad endopod three-fourths the length of the peduncle, 

 the narrower exopod a little shorter. L. Q with developing oostegites, 1-8 mm. 

 d unknown.

 t. 28 f. 4a— r ' 1905 ? C. w., Caiman in: Sci. Invest. Fish. Ireland, 1904 app. 1 p. 10, 35. 



Pseudorostral lobes short, obtuse. Carapace smooth, oval, dorsal line 

 much arched, eyelobe very small. Telsonic segment very obtusely extended 

 between the uropods. Eye wanting. Antenna 1, the 2^^ joint of peduncle 

 the shortest, flagellum of 3 or 4 joints, accessory a minute tubercle. Maxilla 1, 

 palp with 2 filaments. Maxilliped 1 with some 20 branchial leaflets on the 

 epipod. Maxilliped 2, terminal joint as it were embedded in the preceding and 

 carrying 3 apical spines. Maxilliped 3, with denticulate medial margin to 

 joints 3 to 6. Peraeopod 2, 7^^ joint rather stout or in Q slender (Caiman), 

 shorter than 2 preceding joints combined. Uropods as long as the pleon, 

 peduncle twice as long as the endopod or more (Caiman), exopod a little 

 shorter than endopod. L. young d, a little less than 5 mm, immature Q, 

 4'5 mm.

3. C. paeneglabra Stebb. 1912 C. paeneglaber, T. Stebbing in: Ann. S. Afr. 

 Mas., v. lOv p. 172 t. 64. 



Near to C. glabra (nr. 8), size, shape, mouth organs, pellucid spots on 

 carapace, being in close agreement, but the S. African species is rather 

 larger, the pseudorostral lobes are slightly upturned, the carapace is not 

 quite smooth, the eyelobe is more elongate, showing no lenses, the 1^* and 

 2'"^ pedigerous segments are not transversely ridged, the 2"*^ peraeopod has 

 the 7*'^ joint longer instead of shorter than the 5<^^ and 6*^ joints combined, 

 and the 5^^ peraeopods are more slenderly built, with the 2^^ and 5*^^ joints 

 longer relatively to the other joints. L. d about 4-3 mm. y unknown.
