Caudal. There are two imperfect caudal vertebrae, both from the 

 mid-caudal region. One is 67 mm. long, has the anterior end of the 

 centrum 52 mm. high and 48 mm. wide, the posterior end 50 mm. 

 high and 44 mm. wide, and is considerably constricted in the middle 

 width a minimum width of 2i mm. The ends are somewhat concave 

 and the ventral borders of the ends are bevelled off, the anterior 

 more than the posterior. The anterior zygapophysis are small and 

 upwardly directed. The transverse processes arise at the top of the 

 centrum and stand out horizontally. 



In the other, the centrum is 75 mm. long with its end 48 mm. 

 high and broad. It is but little compressed and the ventral surface 

 is flattened. The prezygapophyses are directed strongly upwards, while 

 the transverse processes are small and arise from behind the middle 

 of the centrum. In neither vertebra are the neural spines or the 

 postzygapohyses preserved. 



Scapula. (Cat. No. 3348.) The proximal part of a left scapula is 

 present, lacking the glenoid cavity and the coracoidal articular surface. 

 The greatest breadth at the proximal end was probably 150 mm. 

 The inner face of the scapula is flat, curving strongly inwards 

 proximally; the outer face is lightly convex. Above the glenoid 

 cavity the bone thins rapidly; the anterior border is uniformly thin 

 save for a slight thickening near the coracoid. The supracoraco- 

 scapular concavity is well-marked and large and the deltoid crest 

 strongly developed. There is also preserved a fragment of the upper end 

 which shows that distally the bone was expanded as in Plateosaurus. 

 The narrowest part of the bone has a breadth of 71 mm. and a 

 thickness of 24 mm. 



Humerus. Two left humeri are preserved, one (Cat. No. 3342) of 

 a larger, and one (Cat. No. 3350) of a smaller individual. The two 

 agree closely with one another in general characteristics, although 

 the smaller bone lias been flattened so that the processus lateralis 

 is not so strongly bent as in the larger bone. 



From within the bone is seen to be very slightly S-shaped. The 

 proximal part is very broad, the shaft thin, and the distal end 

 broad. The proximal and distal articular surfaces are strongly 

 inclined to one another. The head of the humerus lies somewhat 

 within the middle line. The anterior edge of the proximal articular 

 surface is a regular curve; the posterior edge has two saddle-shaped 

 prominences due to thickenings at the inner angle and at the caput 

 humeri. This latter is at the extreme end of the bone. At the 

 outer side of the broad, concave bicipital fossa is the processus 

 lateralis, a strong crest lying parallel to the inner border of the
