culse and serratus magnus. The other part arises from the whole 
inner surface of the coracoid. Both parts have a common insertion 
into the ulnar tuberosity, which is close to the head of the humerus.

radialis being cut and reflected.

Sterno-coracoid (fig. 8, St.S). A muscle, asin the Iguana, takes 
origin from the inside of the sternum, and is inserted, very strongly, 
into the antero-internal angle of the inner surface of the precoracoid, 
just external to its articulation with the sternum. 
A dense membrane is attached, on the one hand, to the anterior 
margin of the first rib, on the other hand into the angle of the an- 
terior margin of the shoulder-girdle, between the two parts (fig. 8, 
C. 8) of the subscapularis. This sheet of membrane appears to re- 
present the costo-coracoid muscle of the Iguana. 
The levator clavicule (figs. 1, 5, 6, 7, 8, 13, L) is a very volu- 
minous and more or less double mass. It arises from the basiocci- 
pital, and is inserted into the anterior margin of the scapula, 
overlapped by the omo-hyoid, and conterminous behind with the 
suprascapular. 
Subclavius (fig. 13, 8. C). This muscle, which I before named * 
epicoraco-humeral, but which Professor Rolleston considers to be the 
subclavius, springs from the whole anterior border of the coraco-epi- 
coracoid. Passing downward and backward beneath the deltoid, it 
is inserted into the great tuberosity of the humerus, immediately in 
front of (above, the humerus being vertical) the insertion of the pec- 
toralis, which muscle is superficial to it. The subclavius itself is 
superficial to the antero-external part of the short coraco-brachialis, 
with which (especially toward its hinder part) it is closely connected.
