1. ¢, Germany, aet. 66. January 11, 1894. 
Plate XXXII. Left upper extremity. 
Glenoid tendon, overlying long Biceps tendon and fusing with 
the under surface of the Pectoralis major tendon in its broad 
upper part. About the middle of the pectoral tendon this 
connection ceases, and the tendon bundle becomes narrower and 
more sharply defined. It remains tendinous throughout and 
passes obliquely downward and inward over the Biceps, median 
nerve and brachial artery to be attached to the anterior aspect 
of the internal epicondyle. 
In confirmation of the view expressed as to the nature of this 
variation the right upper extremity of the same subject pre- 
sented the Capsulo-pectoral slip, as a well-marked tendon, con- 
nected with the deep surface of the Pectoralis major; also a 
separate slender tendon from the coraco-acromial ligament to 
the outer margin of the short bicipital head. 
2. g, Ireland, aet. 42. November 13, 1894. 
Plate XX XIII. Left upper extremity. 
A tendon from the glenoid margin, interwoven with the cap- 
sule of the shoulder joint, passes over the long Biceps tendon, 
covered by the Pectoralis major tendon, to the deep surface of 
which it is partially attached, and continues beyond the pectoral 
tendon as a slender but very distinct band, passing obliquely 
downward and inward over the brachial artery and the large 
nerves to the internal epicondyle, blending with the lower quarter 
of Struther’s ligament. 
3. ¢, Germany, aet. 66. January 11, 1894. 
Left upper extremity presents exactly the same arrangement. 
4. $, U.S., white, aet. 23. January 30, 1894. 
Right upper extremity. 
Gleno-ulnar fibres, rather weak in upper portion, on posterior 
surface of Pectoralis major tendon. 
From the lower part of the posterior surface of pectoral 
tendon, and from inferior border of deep reflected part, fibres 
are derived which form a slender tendon, passing down and in, 
superficial to and obliquely across Biceps and brachial vessels 
and nerves, to be inserted on the anterior surface of the internal 
epicondyle. \ 
4. M. BRACHIO-ULANRIS LATERALIS. 
I have placed under this designation certain of the variations 
of the Biceps, constituting accessory third humeral heads, aris- 
ing from the anterior or external surface of the shaft, because a 
careful examination affords grounds for regarding them as dis- 
tal portions of a Gleno-ulnar muscle, which has lost its proximal
