broad powerful transverse processes and a short spine. The bodies 

 measure in length from 60 mm. in the 14th to 65 mm. in the 19th 

 vertebra. The greatest w^idth in each case is about 60 mm., but 

 though the bodies are as broad as long they are so much narrowed in 

 the middle that they appear elongated. On the lower side both 

 ends of the body are truncated obliquely to accommodate well- 

 developed intercentra. Those preserved measure about 40 mm. 

 by 20 mm. The bodies are biconcave but not deeply excavated. 

 From the upper part of the front end of each body passes out the 

 large transverse process. It springs from the greater part of the 

 body, but while the posterior part passes almost directly outwards, 

 the anterior passes upwards and slightly forwards. When viewed 

 from the outside each transverse process is somewhat triangular in 

 shape, the posterior side of the triangle forming the large articula- 

 tion for the rib, and the anterior angle being formed by the anterior 

 zygapophysis. The posterior zygapophysis is of large size, and is 

 situated considerably behind the upper end of the articulation for 

 the rib. The articulation for the rib in the 14th vertebra measures 

 78 mm. in length, but in the succeeding vertebrae the upper part of 

 the articulation becomes steadily reduced. The spines are short and 

 stout. That of the 16th vertebra measures about 28 mm. above the 

 general level of the arch, and the whole vertebra measures 145 mm. 

 in height. The 19th vertebra measures 160 mm. in height. 



The best preserved caudal vertebrae are a series of 5, probably the 

 first 5. Together they measure in length 200 ram. The tips of the 

 spines and of the transverse processes are gone, but so far as pre- 

 served they closely agree with those of Parciasaurus except in size 

 There seem to be no chevrons to these vertebrae. In one or two 

 later caudals the chevrons are well developed. 



Shouldee Girdle. 



A considerable portion of the right shoulder girdle is preserved. 

 It represents the lower half of the scapula and a portion of the 

 coracoid, but it is too imperfect for description. 



Humerus. 



The right humerus is fairly well preserved, and resembles in 

 general that of Pareiasaurns. In greatest length it measures 

 318 mm. It is constricted in the middle and greatly expanded at 

 the ends. The distal end measures 208 mm. in width. As in 

 Pareiasaurns, there is a large rounded prominence for the articula-
