Macalister * describes several varieties of additional coracoid 
heads of the Biceps (catalogue numbers 11-14 incl.). The ac- 
cessory portion may join the main body of the muscle, or else it 
may unite with the normal coracoid head, before that portion of 
the Biceps joins the long head. Additional coracoid origins 
from the Coraco-acromial ligament and from the insertion tendon 
of the Pectoralis minor are also mentioned by the same author. 
2. CoRACO-EPITROCHLARIS. 
As in the case of the Gleno-ulnar head certain instances occur 
in which an additional coracoid head passes to the internal epi- 
condyle. I have met this arrangement in two forms : 
a. Coraco-epitrochlear tendon. 
Cases : 
1. $, U.S. white, aet. 47. March, 1894. 
Plate XXXVII. Right upper extremity. 
A slender, firm tendon arises from the coracoid process at the 
inner border of the short bicipital head and superficial to the 
Coraco-brachialis origin. It passes downward and slightly in- 
ward obliquely over the brachial artery and the large nerves, 
receives near the elbow an accession of fibres from the internal 
intermuscular septum, and is inserted into the internal epicon- 
dyle. 
2. 2, Ireland, aet. 63. November 14, 1894. 
Right upper extremity : 
A thin tendinous slip arises from the intermuscular septum 
betwteen the short head of the Biceps and the Coraco-brachialis, 
passes downward and inward, over the musculo-cutaneous nerve 
to the internal epicondyle. 
The musculo-cutaneous nerve passes entirely below the Cor- 
aco-brachialis, between this muscle and the short bicipital head, 
the former receiving its nerve higher up by a separate branch 
from the outer cord of the brachial plexus. 
3. $, U.S. white, aet. 34. February 1, 1894. 
Left upper extremity : 
A tendon slip arises from the coracoid process and tendon of 
origin of the Coraco-brachialis and short bicipital head ; becom- 
ing free about 2 cm. below the coracoid it passes downward and 
inward as a distinct tendon to be inserted into the internal 
epicondyle.

Left upper extremity : 
A tendon slip from origin of Coraco-brachialis and short head
