38 THE SALAMANDER 



ossifies earlier than the bony region of the ventral portions. ^ Its 

 anterior border fuses to a considerable extent with the bony portion 

 of the pro-coracoid, but its posterior edge only just meets the coracoid 

 at the edge of the glenoid cavity. The angle between the anterior 

 edge of the scapula and the lateral edge of the pro-coracoid is nearly 

 a right angle.

This region of the pectoral girdle forms the anterior part of the 

 ventral plate. It projects almost directly anteriorly from the glenoid 

 cavity, and extends nearly as far forwards as the level of the os tri- 

 angulare on the floor of the pharynx. It is spatulate in shape and 

 slightly dished, with the convexity ventralwards. It is ossified in the 

 region of the glenoid cavity but remains cartilaginous anteriorly, and 

 is only imperfectly demarcated from the coracoid portion by a deep 

 notch — the incisura coracoidea (in. cor.) — which separates the cartila- 

 ginous portions of the two regions. The osseous part of the pro- 

 coracoid is entirely continuous with that of the coracoid except for 

 the foramen supracoracoideum (fo.s.cor.), through which passes the 

 N. supracoracoideus and the corresponding artery and vein. A line 

 drawn from the glenoid cavity through this foramen to the centre 

 of the incisura coracoidea may be taken to represent the boundary 

 between the pro-coracoid and coracoid portions, which may thus be 

 regarded as in an incipient state of separation. The free edges of the 

 cartilage are exceedingly thin. The pro-coracoid forms a prominent 

 lip over the anterior face of the glenoid cavity which presents a 

 definite facet to the head of the humerus. The free edge of this lip is 

 cartilaginous.
