TAPINOCEPHALIDJE. 89 



region of the ischium is broken away. The ilium is de- 

 scribed by Owen in his 'Catalogue/ p. 13, no. 27, and 

 referred to Pariasaurus, while the ischium and pubis are 

 noticed in the same work, p. 11, no. 22, as the right 

 scapula and coracoid of that genus. The entire specimen 

 is figured by Seeley in the ' Phil. Trans.' for 1889, pi. xxi., 

 as the type of Phocosaurus. In woodcut fig. 17, a reversed 

 restoration of the specimen is given, partly based on the 

 corresponding bones of the opposite side, and partly on 

 the Dicynodont pelvis, No. R. 1698 (p. 57). In Seeley's 

 figure the suture between the pubis and ischium is made 

 to pass posteriorly to the foramen ; but from a comparison 

 of the right pubis with that of No. R. 1698, the correspon- 

 dence is so close that it is practically certain that the 

 vacuity is the obturator foramen, and consequently that 

 the ischio-pubic suture should pass through it. The right 

 pubis seems to indicate that this is really the case, since 

 below the sutural surface of the acetabulum there is a 

 flat surface extending obliquely forwards to the foramen, 

 which appears to indicate the line of suture.

43525 S. The right ilium and the imperfect pubis of the same side ; 

 from Vers Eontein. The ilium is noticed by Owen in his 

 ' Catalogue,' p. 13, no. 26, and referred to Pariasaurus. 

 The symphysial portion of the pubis is broken away, but 

 the foramen remains.

43525 t. The proximal half of the right femur ; said to be from Yers 

 {Fig.) Eontein. Noticed by Owen in his ' Catalogue,' p. 13, 

 no. 28, and figured by him in the ' Quart. Journ. Geol. Soc.' 

 vol. xxxvi. pi. xvii. fig. 8. The distal surface has been 

 cut and polished. The long and straight great (outer) 

 trochanter found in the Dicynodont femur is wanting. 

 The mineralogical condition is like that of the type of 

 Tajnnocephalus, suggesting that the specimen is from 

 Jan Willem's Eontein.
