Head of male. C. Fornix and margin of ephippium of female. D. Postabdomen of female, C. laticaudata, and in the latter the front of the head is said to bo smooth, while the postabdominal claws are denti- culate. The ephippium is marked off from the valves by a broad, clear space which is free from reticulations, and the ephippium itself is covered with small reticulations, each with a small knob or boss in the centre, but with no spines. 24*.
