(as Dicynodon tigriceps). The presence of a distinct rib 

 to each vertebra is clearly shown, whereby the specimen 

 differs from the entire sacrum figured in the latter plate 

 under the same name (see pp. 117, 118). 



Presented by A. G. Bain, Esq., 1 853. 



38241. Two later sacral vertebras, apparently belonging to the same 

 (Pig.) individual as the preceding ; from the same locality. 

 Figured by Owen in the ' Trans. Geol. Soc' ser. 2, vol. vii. 

 pi. xxxiii. figs. 6, 7, and noticed in his ' Catalogue,' p. 42, 

 no. 69, as Dicynodon tigriceps. The expansion of the ribs 

 for attachment to the ilium is well shown, and the speci- 

 men agrees in all essential characters with the sacra 

 described as Platypodosaurus (p. 63). 



Presented by A. G. Bain, Esq., 1853. 



47105. Portion of the imperfect sacral region of a large form; from 

 the Karoo system of the Cape Colony. 



Presented by A. G. Bain, Esq., 1853. 



R. 725 z. The centrum of a caudal vertebra of a comparatively small 



form : from Natal. Probably associated with jNo. E. 725 y. 



Presented by Prof. T. Rupert Jones, 1886. 



The following vertebra? have more compressed centra than the pre- 

 ceding, and some of them may be referable to the Theriodont 

 Galesauridas. 



R. 869. Two imperfect dorsal vertebrae of medium size ; from the 

 Cape Colony. These specimens were found with skulls of 

 Ptychosiagum, and not improbably belong to that genus. 

 The centra are long and much compressed, with moderately 

 deep terminal cups. On the left side a portion of a rib 

 remains, with its head resting on the capitular articular 

 surface of the centrum. 



Purchased from T. Bain, Esq., 1880. 



R. 1704 f. An imperfect lumbar (?) vertebra, approximating in size 

 to the preceding; from the Cape Colony. The centrum 

 is comparatively short. Xo history. 



R. 1704 g. Four conjoint imperfect dorsal vertebrae of a smaller 

 form; from the Cape Colony. The centra approximate in 

 contour to No. It. 869. Xo history.
