318 Prof. H. G. Seeley on Euskelesaurus Brownii. 



Sir R. I. Murchison, and acknowledged by him ; but no 

 account of it was publislied, and I have been unable to trace 

 the specimens. Mr. Brown, finding that his fossil aroused 

 less interest in this country than might have been expected 

 from the interest taken in his discoveries in Cape Colony, 

 consigned a third box of the remains to the Museum of the 

 Jardin des Plantes, where the specimens are exhibited. Some 

 were figured by M. Paul Fischer (Nouv. Archiv. du Museum, 

 Mem. tome vi. pis. x., xi.), and give evidence of caudal 

 vertebrae with chevron bones and the neural arch, distal row 

 of the tarsus, phalanges, and the nearly entire pubis, which I 

 found to be similar to the pubis of Massospondylus in 

 January 1889. 



The further specimens entrusted to me by Mr. Brown 

 comprise the maxillary and premaxillary bone, a chevron- 

 bone, the expanded proximal part of a rib, three claw- 

 plialanges (and a fourth imperfect), and six digital phalanges 

 of the foot. 



There are two vertebras in the Albany Museum from 

 Penhoek which are probably referable to the same species. 

 One of these gives the characters of the dorsal region, the 

 other is apparently a late caudal vertebra. 



The osteology of the animal is therefore very imperfectly 

 known, since no part of the fore limb or shoulder-girdle 

 appears to have been preserved in the three known collections. 

 Ihe vertebral column is almost untouched, and is apparently 

 still in the rock. The few specimens now available for study 

 seem to substantially support Prof. Huxley's interpretation of 

 1866 * in indicating resemblances to Megalosaurus ; the 

 resemblances are especially interesting with Massospondylus, 

 so that the type may be placed in the Saurischia in near asso- 

 ciation with the latter genus and Zanclodon^ though with a 

 nearer approximation to Megalosaurus. 



The evidences for these conclusions are given in the follow- 

 ing account of the several bones. 



Premaxillary and Maxillary Bones o/' Euskelesaurus 

 Brownii [Huxley). (Fig. 1.) 



The left maxillary and premaxillary bones are exposed on 

 the internal aspect of the jaw, so as to define its form fairly 

 well except at the extremities of the premaxillary in front, 



* Mr. K. Lydekker (Cat. Foss. Eept. Brit. Mus. pt. 4, 1890, p. 252) 

 refers this fjenus to the Stegosauridfe ; but no evidence has been <>-iven in 

 support of this determination, and I have observed no character common 

 to it and the Ornithischia.
