BOONSTRA, (With Plate XVIII and 5 text-figures) In the collection of the South African Museum there is a specimen ( 4323) collected by Haughton on the Merweville Commonage in 1917. This had been entered in the register as a Gorgonopsian, presumably because of its small size. The specimen as preserved consists of the anterior third of a small skull, the major part of a manus, a tarsus, a nearly complete femur, a radius, a fibula, part of the head of the humerus, a coracoid, a series of caudal vertebrae and some other fragments. This is the first specimen of a South African Deinocephalian in which most of the bones of the fore- and hindfoot have been found in articulation. The Skull (fig. 1) In the accompanying figure the lateral aspect of the snout is given, with the missing part of the skull indicated by broken lines. The snout is very similar in general build to that known in the large Anteosaurus, although in size it is less than ^ of Anteosaurus obeli. The nostril is not terminal; the alveolar border, anterior to the canine, sweeps sharply upwards; this reduction of the premaxilla creates the space necessary for the large anteriorly directed anterior incisors, whose function has become that of snatching, piercing and tearing teeth (cf. mechanical grab); the five upper incisors, increasing rapidly.
