1898.] MYOLOGY OP THE TBRRESTKIAL CAElflVOEA. 183 



many respects it more closely approaches the Cauidaj than the 

 Felidge. The following are the chief Feline characteristics : — 



(1) The iho-tibiahs (sartorius) is single. 



(2) The caudo-femoralis (agitator caudse) reaches the patella. 



(3) The gluteus ventralis (quartus) is present. 



The following are the chief Canine characteristics : — 



(1) The pronator quadratus reaches as far as the oblique ligament, 



i. e. to close to the top of the radius and nlna. 



(2) The supinator longus is absent. 



(3) Only the tendon of the tibialis posticus is present. 



(4) The accessorius is absent. 



(5) The flexor brevis digitorum pedis has no muscular fibres in the 



sole. 



The following two points are common to both Felidse and Canidse, 

 but go to show that the animal has no Viverrine tendencies : — 



(1) The subclavius is absent. 



(2) The semitendiuosus has no caudal head. 



(3) The rhomboideus capitis is present. 



"We should like to emphasize the fact that we have never had an 

 opportunity of dissecting a specimen of Cyncelurus, and that our 

 facts are gained from Eoss's description. This is in some ways an 

 advantage because his account is an absolute statement of facts 

 set down without any view of proving a theory ; it is a disadvantage 

 because there are many points on which we would like detailed 

 information which necessarily seemed of little or no importance 

 to him. 



The Fossa (Grijjitoproeta ferox) of Madagascar is another animal 

 about whose position systematists are not quite agreed. We have 

 dissected two specimens of this animal (13, 14), and Beddard (VII.) 

 has published some notes on the myology of a third. So far as its 

 muscles go we regard it as a most typical viverrine animal, and the 

 three specimens of which we have records agree so well that we 

 feel that we can speak with some confidence on its myology. 



The Aard Wolf of South Africa (Proteles cristatus) has been 

 placed, in our list of animals, at the end of the Vivsrridae in 

 deference to what we believe is the view of most systematists at the 

 present time ; its muscles, however, point to its much closer relation- 

 ship with the Hyaenidse, and we subjoin the facts on which our 

 opinion is based : — 



a. Viverrine tendencies. 



(1) The cephalo-humeral is inserted into the forearm. 



(2) There is a tendon to the pollex from the flexor profundus 



digitorum. 



/3. Hysenine tendencies. 

 (1) The pronator quadratus occupies the whole length of the 

 forearm.
