Panturichthys isognathus Poll, 1953

Irvine name. Species omitted from book. Specimen in collections originally labelled as Pythonichthys microphthalmus (Regan, 1912) but later re-identified as a Panturichthys species by A. Ben-Tuvia.

Reference material. Accra , Ghana, from stomach of Blue shark ( Prionace glauca ), January 1938, coll. V. J. Foote — BMNH 1938.12 .15.4 (one: 300 mm SL) .

Distribution. Known from the coast of West Africa from Ghana to Angola (Blache, 1968).

This specimen, which is in poor condition having been in a shark stomach, appears to be only the second adult example of this species reported. The dentition very closely matches that of Panturichthys isognathus illustrated by Blache (1968: figure 20) and the number of vertebrae (148) is close to that of the holotype (141). Panturichthys longus , which also occurs in the Gulf of Guinea has 209–227 vertebrae, whilst P. mauritanicus , which is known from Morocco to Guinea, has 164–176 vertebrae.
