First molar crown. Right ramus of mandible of Gomphoc/nathns {DiaMe))wdo)i) dimorphodon, seen from above, showing extent of symphysis and roots of teeth iu the diastema. In the middle of the maxillary diastema on tlie left side, behind the canine tooth is one crown quite perfect, small, strong, sharply pointed, recurved, which may be an early premolar. It is the typ^ of cutting ])rehensile crown which may have existed in the specimen o£ G. poh/phagus from the same locality, numbered in the Brit. Mus. 2576-7, and may liave been present in the allied species indicated by this fragment of the right mandible. The bases of those teeth arc.
