It is a small, short, and light bone, with fairly small distal and proximal expansions which apparently stand at only 15° to each other. The delto- pectoral crest is very short, and the proximal corner on the anterior dorso-ventral line is prominent ; the proximal surface is a long narrow ribbon, very imperfectly divisible into separate surfaces ; the trochlear fossa is fairly shallow, but long and different in shape to the other Pareiasaurs; the distal swelling is weak and directed more obliquely forwards than in all other humeri, and it is also more terminal than ventral; the ectepicondyle does not extend distally to this surface, with which it is distally confluent. The entepicondylar foramen is situated much ventrally. Ulna, radius, and foot are unknown. Anthodon serrarius Owen. Anthodon minusculus Haughton. This generic description is based chiefly on specimens which have been referred to A. serrarius ; but is also applicable to the two distal.
