They are implanted in shallow sockets in the maxillary and premaxillary bones, and are anchylosed to the sockets. For the lower third, the outer surface presents shallow vertical grooves, conformably with the plicated char- acter of the internal structure. The upper portion is smooth, and its internal structure presents merely radiating tubes of ivory, and coucen- Fig. 141.—Baphetes planiceps, (a) Fragment of maxiUarybone showing sculpture, four outer teeth, and one inner tooth; nat. size.

The whole of these characters are regarded as allying the animal with the great crocodilian frogs of the Trias of Europe, first known as Cheirotherians^ owing to the remarkable hand-like im- pressions of their feet, and afterwards as LahyrlntJiodonts, from the beautifully complicated convolutions of the ivory of their teeth. The only additional remains attributable to this creature, found since the publication of Professor Owen's description, are a bone and a scute or scale. The former may be a scapular or sternal bone, and if so, would warrant the belief that the creature possessed anterior limbs of considerable size; the proportion relatively to the skull being much the same as in the American bullfrog. The latter is marked in the same way as the bones of the head, and would indicate that Baphetes was protected by bony dermal scales, resembling those of the crocodile. Of the general form and dimensions of Baphetes, the
