Small acutely pointed teeth are present in the lower jaw and on the vomer, palatines, and tongue ; the maxillary is broad, rounded posteriorly, without supra- maxillary. There are two nostrils on each side which are superior rather than lateral in position and lie near the end of the snout in front of the anterior end of what appears to be an elongate supraorbital bone ; the head is flattish above and the frontals are slightly raised above each eye.
