332 THE SKELETON OE ETJRYCARPFS OWENI. [May 1900, 



margined by a slightly tumid round border, such as often margins- 

 cartilaginous surfaces. With this area the distal articular end of 

 the femur is in loose contact. The other surface, which is longer 

 than wide, looks as though it might have supported a patella. No- 

 trace of such a bone is preserved. 



The slender fibula is slightly curved ; it appears to extend from 

 the posterior outer extremity of the tibia, and ends distally in a 

 moderately expanded truncation. 



Below these bones is a large tarsal bone apparently, as in 

 Pareiasaurus. The fibula, which is prolonged a little farther distally 

 than the tibia, appears to be attached to the inner margin of the 

 same bone. The specimen, however, is not clear at this point, where 

 a fracture has passed through the tarsal bone, removing the im- 

 pression of the hind foot. The foot was probably lost when the 

 slab was collected by the original finder, for Mr. Thomas Bain, who 

 had seen it, only spoke of one hand as pointed out to him. I have 

 some reason for believing that the other half of the specimen, show- 

 ing the right side of the animal, may still exist in some private 

 collection in Cape Colony, though I have been unable to hear of it. 



The recovery of the missing half of the Murray slab, with 

 evidence of the skull and pelvis which it would give, is greatly to be 

 desired in order to complete our knowledge of this fossil animal. 



Armour. (PI. XXI, v.a.) 



Besides the armour which appears to have been present upon 

 the limbs, the fore part of the body carries upon the ribs and 

 vertebras large granules, and thin oblong bony plates, which may 

 measure | inch in length and | inch transversely, but the markings 

 are too obscure for description. They are evidence for armour on 

 the flanks of Eiirycarpus, with the plates shown in one close-set 

 longitudinal row on the under part of the front of the body, such 

 as occur in Labyrinthodonts. 



The locality, Sneeuwberg, from which this animal was obtained^ 

 had already yielded to Mr. A. G. Bain Lycosaurus pardialis, Tigri- 

 suclius simus, Cynosuchus suppostus, Sccdoposaurus constrictus, and 

 Dicynodon leoniceps. It would therefore appear to be one of the 

 chief localities for the Lycosaurian types of Theriodontia, and to be 

 on the horizon of the Dicynodon-beds. 



EXPLANATION OF PLATE XXI. 



Photographic reproduction of the cast of a portion of the left side of the 

 skeleton of Eury carpus Oweni, about one-third of the natural size. It 

 shows the ventral aspect of the vertebral column (v) and ribs (r), with 

 traces of armour (v.a.), the shoulder-girdle (8), and portions of the fore- 

 limb (k, H) and hind-limb (F,f, t). 



Discussion. 

 Dr. H. Woodward spoke, and Mr. A. Smith Woodward replied;
