On the Presence of a Museulus coraco-olecranalis in the Domestic 
Cat (Felis domestica)'). — 
By C. F. W. McCuvrz. 
With one Figure. 
So far as known to the writer the Musculus coraco - olecranalis 
has never been described as occurring in the cat. This muscle has 
been found in man by GRUBER, MACALISTER ?), LE DOUBLE?) and 
Popow?), and has been described by them as arising from the coracoid 
process of the scapula, to be inserted, with the triceps, into the ole- 
cranon process of the ulna. In addition to its coracoid origin, Mac- 
ALISTER and LE Douse state that, in man, this muscle is also re- 
inforced by fibres from the capsule of the shoulder joint. The Mus- 
culus coraco-olecranalis appears to be a constant subdivision of the 
so-called triceps in many of the Amphibia and Reptilia. Among cer- 
tain of the latter (Lacertilia), it appears to have been replaced by a 
ligament (Testur)?). It is also present in some birds, though in a 
reduced condition, and is called by FÜRBRINGER*) the Musculus an- 
conaeus coracoideus. 
The writer’s attention was called to this muscular anomaly by 
his Assistant, C. F. SILVESTER, and it is the only instance, in over 
one hundred cats hitherto examined, in which a similar muscle has 
been met with. The muscle was present only on the left arm of an 
1) Humeury, In Observations in Myology, gives the name coraco- 
olecranalis to a muscle in Cryptobranchus japonicus which arises from 
the coracoid process and is inserted, with the three heads of the triceps, 
into the olecranon process of the ulna,
