adult female cat and, unfortunately, its nerve supply could not be 
ascertained, as the nerves had been cut away by a student before the 
muscle was noticed. 
The so-called triceps or the Musculi anconaei of the cat, have been 
fully described by Strauss - DÜRCKHEIM !), MIVART ?) and WILDER ?°). 
Much difference exists, however, concerning the nomenclature given by 
these authors to the various subdivisions of the triceps, hence, the 
following comparative table is given in order to avoid confusion.

The nomenclature given to these muscles in the dog by ELLEN- 
BERGER and Baum, so far as it applies to the corresponding muscles 
in the cat, will be used in the following description. 
The form of the M. coraco-olecranalis, as found in the cat, is not 
unlike that of the human digastric, as it consists of two fleshy mus- 
cular bellies separated by an intervening tendon (Cor. ol. in Figure). 
This intervening tendon, which lies nearly opposite the middle of 
the posterior border of the M. biceps, is flattened and measures about 
15 millimeters in length. 
The M. coraco-olecranalis arises, by means of a short tendon, 
from the tip of the coracoid process of the scapula and its fibres, at 
this point, are closely interwoven with those of the M. coraco-bra-
