Varanosaurus acutirostris, BrolU. 305 



articular region is clearly marked off from the rest of the 

 bone, and the whole glenoid cavity forms a screw-shaped 

 piece of the snrface of a cylinder whose axis stands in a 

 vertical plane pointing downwards towards the front at an 

 angle of about G0°.

Varcmosntirus ncutirostris, Eroili. Type specimen, X 1. 

 Left cartilaginous shoulder-'jirdlo. 



Tlie anterior coracoidal element is clearly separated from 

 the scapular by a suture, which has parted, allowing tiio 

 bones to separate by a little less than a millimetre. The 

 anterior coracoidal element has a process which joins with 

 tliat of the scapula which supports the anterior end of the 

 glenoid cavity. 



Behind this process is a deep pocket, from Avhich the 

 coracoid and glenoid foramina must start. If the suture 

 between tliis bone and the scapula be correctly determined, 

 of which 1 think there is no doubt, the bone only supports 

 an extremely small piece of the glenoid cavity, if any at all. 



The posterior coracoidal element is a small bone separated 

 from the scapula by an obvious suture and from the anterior 

 element by a faint and incom|)lcte one. 



Tliat the bone is really distinct is certain, as it is indicated 

 by the texture, the shape of the internal surface, and its 

 perfect resemblance to Ophiucodon. The bone carries a large 

 part of the glenoid cavity, and has a low process on its 

 posterior edge.
