muscles and to the anterior part of the transversus 
abdominis muscle; (c) the pectoralis (19), a large 
nerve leading to the muscle of that name; (d) 
cutaneus pectoralis (18), fine branches from the 
XIth spinal nerve to the integument of the axilla 
and the neighboring parts of the breast; (e) coraco- 
brachialis (22) to the like named muscle; (f) cutan- 
eus brachii et antebrachii medialis (25 + 42) to 
the medial side of the integument of the upper 
and fore arm; (g) brachialis longus inferior (21), a 
large nerve that supplies the biceps and humero- 
antebrachialis inferior muscles, and then divides 
into the medianus and ulnaris inferior nerves; (h) 
subscapularis (29) to the like named muscle; (i) 
scapulo-humeralis profundus (36a) to the like 
named muscle; (j) axillaris, a large stem that 
divides into two main twigs that lead to the skin 
of the lateral side of the upper arm, to the proximal 
part of the forearm, to the humero-radialis muscle, 
and to the deltoides coraco-sternalis muscle; (k) 
dorsalis scapule (posterior) (31) to the deltoideus 
scapularis muscle; (1) teres major (29b), one 
(alligator) or two (crocodile) middle-sized nerves
