PROFESSOR WOOD ON THE NECK- AND SHOULDER-MUSCLES. 
homologue the muscular slip described and figured from the Crocodile by Professor 
Rolleston, in his valuable memoir on “ The Homologies of certain Muscles connected 
with the Shoulder-joint” (p. 626 and fig. 3, 0 , i), as “a muscular fascicle which arises 
from the second sterno-costal cartilage in the same series as the external oblique and 
intercostals, but which may also be looked upon as homologous with an anterior segment 
of the rectus abdominis , which is often not distinguishable from the former of these 
muscles. It ends in a delicate tendon, which loses itself along the coracoid groove in 
the sternum and the origin of the pectoralis major .”
