492 PROF. ST.-GEORGE MIVART ON THE ZLUROIDEA. [June 6, 
Myo.uoey. 
The muscles of the Felide have, as every one knows, been most 
perfectly illustrated and described, with his peculiar nomenclature, 
by Straus-Diirckheim in his splendid work ‘ Le Chat.’ The mus- 
cles of the Cat have also been shortly described under their com- 
monly known names, and partly illustrated from fresh dissections, 
by me’. The muscles of various Felide, of the Genet, and of the 
Hyzena have been figured in Cuvier’s magnificent ‘Recueil des 
Planches.’ The muscles of the Civet have been described by Prof. 
Macalister? and by Messrs. Young * and Davis *, and those of Cro- 
cuta by Dr, Watson *. 
With these references, I shall content myself with shortly noticing 
the myological conditions which I have observed in the specimen of 
Genetta tigrina dissected by me, pointing out their resemblances and 
differences from those found by me in the Cat, by Prof. Macalister 
in the Civet, and by Dr. Watson in Crocuta. 
Muscles of the Pectoral Limb. 
Pectoralis.—I found this in the Genet to be as in the Cat, save that 
one muscular mass corresponds with what I have described * as the 
Ist, 2nd, and 5th parts of the Cat’s pectoralis, while the part which 
seems to represent the Cat’s 2nd portion extends three fourths down 
the humerus. What corresponds to the 4th part of the Cat’s pec- 
toral is here inserted into the head of the humerus around the ten- 
don of the biceps, and (mainly) on the greater tuberosity. 
In Crocuta the pectoral is inserted into the whole length of the 
humerus from the bicipital groove to the elbow, and is divisible into 
a superficial and a deep stratum. 
The rectus abdominis extends the whole length of the sternum ; 
and there are (as in the Civet) seven tendinous inscriptions. 
The scaleni are as in the Cat, except that the longer one reaches 
from the 5th to the 8th rib: from the 3rd to the 6th in the Civet. 
There are but two scaleni in Crocuta, but there are three in Hyena 
brunnea and the Civet. 
The subclavius is represented by a small muscle which goes from 
the first rib to the rudimentary clavicle, as also in the Civet. 
The ¢rapezius has the same general conditions as it has in the 
Cat’. Its anterior part is very small in the Hyzenas’*. 
The cephalo-humeral is as in the Cat, as it is also probably in the 
Civets and Hyznas. In the latter it is of enormous strength °.

7 Prof. Macalister reckons as part of the trapezius what I and Dr. Watson 
consider to be the cephalo-humeral (or levator humeri).
