Etmopterus abernethyi , holotype, 338 mm. total length.

Note greater concentration of chromatophores in lower half, and black pits which are most numerous at demarcation line between light and dark regions. Maturity. The claspers on the holotype lack the external spurs which might be expected in a mature specimen; the female of 278 mm. has not been examined for its state of maturity though its small size in comparison with the immature male suggests that it, too, is immature. Discussion. As in E. baxteri, the thorn-like denticles of E. abernethyi provide a ready character for the separation of this species from frontimaculatus, pusillus and granulosus which have truncate denticles, and from paessleri in which the denticles are.
