Muscles of the Hind Limb. 



Ectogluteus (Gluteus maximus). — This muscle is fairly constant in 

 the Carnivora, it rises from the posterior two or three sacral 

 spines and from the transverse processes of a like number of 

 caudal vertebrae. Occasionally it derives a slight origin from 

 the ilium. It is inserted into the femur, usually just below the 

 great trochanter, as well as into the fascia lata. Anteriorly 

 its edge is continuous with that of the tensor fasciae femoris, 

 posteriorly with that of the biceps ; indeed, the sartorius, tensor 

 fasciae femoris, ectogluteus, and biceps form a muscular sheath 

 round the outer two-thirds of the thigh, and it is often quite 

 difficult to determine where one muscle ends and the other begins. 

 Among the Felidae the foregoing description applies to Felis lea 

 (1, 2, 3), F. tigris (4), F. pardus (5, 6, 7), F. pardalis (8), F. catus 

 (9), and Cyncelurus (12). Among the Viverridae it applies to 

 Gryptoprocta (13, 14), Fiverra (17), Viverricula (19), Geneita 

 tignna (20), G. vulgaris (23, 24), Paradoxurus (25, 26), 

 Herpestes nepalensis (29), H. griseus (30), and Gynictis (31). 



Young (VIII.) describes the muscle in Viverra (16) as being 

 inserted into the whole length of the shaft of the femur, though 

 this description probably includes the agitator caudse. Cuvier and 

 Laurillard (XII.) found the muscle divided into three parts 

 in Genetta tigrina (22) ; of these one is evidently the agitator 

 caudae, while the rest consists of a superficial and a deep layer. 

 This arrangement is clearly exceptional, as it was not noticed in 

 any other specimen of Grenet. Proteles (32) seems to differ from 

 the typical arrangement in not having the ectogluteus continuous 

 with the biceps.
