Oxycephalus clausi Bovallius.

Oxycephalus clausi Stebbing, Rep. Voy. “Challenger,” 29, p. 1583, pl. 202, 1888.

One specimen cast up on Terrace's Beach, Sunday Island, and two imperfect specimens washed up on Flat Beach.

The perfect specimen agrees closely with Stebbing's descriptions and figure. He points out that the species is nearly allied to O. edwardsii G. M. Thomson, which is occasionally washed up on New Zealand shores, but that there are differences in the gnathopods, the fifth peraeopod, &c. In the Kermadec specimens. “the postero-lateral angles of the first three segments [of the pleon are] produced into a short sharp point, behind which, at some distance, the hind margin forms a similar point” as described by Stebbing, while in O. novae-zealandiae it is only the hind margin that is produced into a point.
