Pectoral girdle. 



Of this girdle only the left coracoid is visible : it is 

 exposed from the visceral surface. The fragments of 

 which it is made are set in plaster and are probably 

 wrongly arranged. 



The glenoid end is well preserved and the part joining 

 it to the median edge is genuine. The articular facet for 

 the scapula is 55 cms. long, that for the glenoid cavity 

 being 9 cms.

The anterior edge is certainly artificial ; it now forms 

 a uniform convexity of which the inner part (that from 

 the end of which the dotted line in the figure {Fig. 4) 

 starts) is probably original ; the other fragments compo- 

 sing it may belong to the posterior end of the bone. The 

 median edge is well preserved, it is practically straight, 

 and in the region between the glenoid cavities shews the 

 usual hump, the bone here being more than 4 cms. thick. 



The posterior border is completely broken away.
