250 _ TRANSACTIONS OF THE [May 13, 
A slightly marked tendinous gleno-ulnar slip passes from the 
capsule of the shoulder over the intertubercular groove, with 
intermediate attachment to deep surface of pectoral tendon, to 
the angle of union between the long and short bicipital heads. 
From the anterior surface of the lower part of the Coraco- 
brachialis, near its insertion, is derived a slender muscle-slip, 
which, becoming tendinous, passes obliquely down and in over 
brachial vessels and median nerve to be attached to the internal 
epicondyle. 
The left upper extremity of the same subject presents a small 
tendinous band passing from the capsule to the deep surface of 
the Pectoralis major tendon. 
II. Coraco-ULNAR HEAD. 
This muscle is found usually very closely fused in its proxi- 
mal part with the short or corao-radial head of the Biceps, and 
with the Coraco brachialis. But its distal portion appears fre- 
qnently as the ‘ third internal humeral head.” 
The following variations are to be noted : 
1. CAPSULA-INTERMEDIATE TENDON. 
Origin: Tendon fibres derived from the capsule of the 
shoulder joint between the coracoid process and bicipital groove. 
The slip passes down to the angle of fusion between the long 
and short heads of the Biceps.
