Coracoids. The coracoids are short and very thick. 

 They are united in a long, median symphysis, which 

 forms a marked ridge when the girdle is viewed as a 

 whole. This symphysis is at least 6 cm. deep between 

 the glenoid cavities. The posterior portion of the cora- 

 coid is small, but the bone is never much less than 2 cm. 

 thick. The glenoid part of the coracoid is very thick, 

 and presents the usual two facets, one 6 cm. long facing 

 the scapula, and the other 1 1 cm. long forming part of the 

 glenoid cavity. 



Fig, V. Right Scapula of Sfhejtarosauriis Dawkinsi, type 

 specimen, x \. Viewed horizontally from within. This view 

 shews the downward projection of the anterior ramus and 

 the dorsal ramus. 



Scapula. The scapula is a trihedral bar with one of 

 the faces directed ventrally ; the dorsal ridge is produced 

 into the dorsal ramus, which is directed dorsally and to 

 the back. 



The ventral surface is very strongly curved, so that in 

 side view the anterior ends of the scapulas project down- 

 wards below the level of the coracoids.
