C. 1. 137 mm., C. b. 14'6 mm. 



In this specimen the sides of the carapace are nearly parallel, and the notches in the 

 same very small, the last one scarcely visible. Outer supra-orbital notch subtriangular. 

 Infero-orbital margin as represented in Caiman's fig. 10 (op. cit.). An arcuate subhepatic 

 ridge which is lost outwai'dly in a cluster of granules.

Seychelles, 34 fms., Sta. F 8 ; 1 $ ovigerous. 



C. 1. to tips of frontal teeth 14 - 9 mm., C. b. 15 - 5 mm. 



The teeth of the carapace are somewhat different from the descriptions and figures of 

 Miers and Caiman. Median sinus of front V-shaped, but with the bottom of the sinus a 

 little rounded. From the frontal teeth to the tip of the innermost orbital tooth the 

 margin is distinctly sinuous ; inner orbital sinus a narrow slit ; next sinus narrow at the 

 base, widening anteriorly ; beyond this there is a third sinus which is triangular. Infra- 

 orbital sinus narrow but open. Lateral teeth defined by narrow, almost horizontal, 

 sinuses ; as in the preceding species, there is a faint indication of a third tooth and 

 sinus.

Carapace about £ as long as broad, subhexagonal, regions separated, surface covered 

 with short dark hairs which do not obscure the tubercles or granules arranged regularly 

 either singly or in groups, as follows : 3 on the nasogastric region, 3 on each protogastric
