White, at Donnybi'ook, in the Tarkastad disti-ict. The type 

 t^peciiiieus in the liiitish Museum, described by Owen, were sent 

 to London b}^ Dr. Atherstone, and in the British Museum catalogue 

 they are stated to have come from " Tafelberg," but there is no 

 doubt the London specimens were also collected by Mr. White, at 

 Donnybrook. These specimens are in a ferruginous fine-grained 

 sandstone, and as the bones are usually softer than the matrix, the 

 specimens are difficult to develop and the sutures and delicate 

 details of the bones are usually but imperfectly shown. The 

 second series of specimens were collected by Messrs. A. E. and H. 

 Trollip at Fernrocks, near Tafelberg Station. They comprise a 

 large series of weathered and broken nodules of indurated fine- 

 grained sandstone, in which are impressions of skulls and other 

 bones of Prorolojj/ioN. Li most cases all traces of the bones is 

 completely weathered away, l)Ut as the matrix is almost as hard as 

 fliut most perfect impressions remain. In many specimens the im- 

 pressions indicate that the bones have been imbedded in almost 

 undisturl)ed positions. In others, the bones, when imbedded, 

 have Ijeen consideral)ly displaced. By taking casts of the various 

 impressions it is i)()ssil)le to get the details of almost every bone of 

 the skeleton. As 1 intend elsewhere to publish a full account of 

 the osteology and aliinities of ProcoJophon, I shall in the present 

 paper merely briefly describe the various specimens in the 

 Museum on which the detailed account will l)e l)ased. 



The si)ecimens represent the remains of animals of various 

 sizes, l)nt as in the one locality large, small, and medium sized 

 specimens occur, and the characters, other than size, which 

 distinguish them, are unimportant, I think all the specimens nuiy 

 safely be refei-ivd to the one species, Procoloplion Iriijonicc'iia.

1. An almost pei-1'eet skull with the lower jaws in position. Tiie 

 bo;ies aie slightly crushed and the sutures not .very distinctly seen. 

 The right jngal arch and most of the right lower jaw are hidden 

 by matrix. The sifeeimen is valuable as showing the sncnit in 

 almost perfect condition. The nasal bones are continued forwards 

 in advance of the })lane of the incisor teeth, and the anterior nai-es 

 are direcleil outwards and downwards. The jjremaxillaries, which 

 each bear li teeth, are anchylosed together, and send forwards and
