greatest breadth, probably for the ligamentous articulation of the sternum. The 
surface for articulation with the scapula has a length of 150 mm. and a greatest 
breadth, at its junction with the glenoid border, of 90 mm. The coracoid forms 
about one half the glenoid cavity and the glenoidal surface meets the surface for 
articulation with the scapula at an obtuse angle. Between the inferior margin of 
the glenoid cavity and the inferior border there is a rather deep notch in the pos-

terior border of the coracoid. The foramen is large and is situated about 35 mm. 
beneath the coraco-scapular suture. It is elliptical in outline with the vertical 
diameter the longer. ‘The dimensions are 57 mim. for the vertical and 30 mm. for 
the transverse diameter at the external opening. The distance from the glenoid 
border to the sutural surface at the antero-inferior angle is 295 mm. The distance 
from the postero-inferior angle to the anterior border just beneath the coraco-scapular 
suture is 350 mm. 
The Scapula (Figs. 17 and 18).— The scapula displays the extreme development 
of that form shown in Morosawrus with broadly expanded extremities. I cannot 
describe the characters better than to give the measurements. The breadth of the
