The associated tooth on the type slab (), which is 1-6 cm. high, 07 cm. across the base and split down the middle, was figured by A. S. Woodward (1891, pi. 16, fig. 4) and described as " straight and regularly tapering, moderately com- pressed ". The counterpart, an external impression (Text-fig. 58) shows the tooth to be very little compressed, and perfectly smooth in the upper half. There are about fourteen deep basal vertical grooves which almost disappear about 0-6 cm. height but which are in fact continued faintly, at first with subsidiary grooves, for. Fig. 59. Pseudosauripterus anglicus (A. S. Woodward). Cast of right entopterygoid referred to this species. Church Quarry, Farlow. (See PI. 47, fig. 1.) X 1-5. some distance before finally disappearing. The wide conical cavity is seen up to 0-9 cm. This tooth has a rather Rhizodont aspect and its reference to this species is questionable. From the same collection and locality as the type scales and the tooth comes a most interesting specimen not mentioned by Woodward. This is a right entoptery- goid, now an external impression, in counterpart (PI. 47, fig. 1 ; Text-fig. 59). It seems likely to belong to this fish but there is no comparable material of this family for comparison. The palatine region is wide and the quadrate part a long narrow curved bar, the smooth outer margin of which bordered the wide adductor fenestra,.
