THE ANATOMY OF THE INDIAN ELEPHANT. 23 



294, fig. 2 (part of ^, and in 294, fig. 2 g). The biceps of Cuvier 

 and Laurillard includes also what we have described as the pos- 

 terior part of glutcBus maximus. 



A strong band of fascia is continued from the back of the 

 leg to the calcaneum ; hiceps passes into the oblique upper edge 

 of this fascia, and the tendon of gastrocnemius externus blends 

 with its deep surface. 



Semitendinosus arises by fleshy fibres from the ramus of the 

 ischium, and ends about the middle of the thigh in a thin tendon, 

 which is lost in the fascia of the inner and back part of the 

 thigh. 



C. and L.— 274-5 ; 285-6 ; 287-8 ; 289, figs. 1, 3, 4 ; 294 (r). 

 Drawn as passing to the inner side of the tibia, and ending in a 

 distinct tendon. 



Semi-meiiibranosus arises by a double tendon. The external 

 head, long, round, and slender, is attached to the great sacro- 

 sciatic ligament and the side of the sacrum. The other, square 

 in section, and tendinous upon its deep surface, springs from the 

 tuberosity of the ischium. The muscle ends in a flattened 

 tendon about three inches below the knee-joint. This tendon 

 divides into two parts, of which the anterior, broad and flat, is 

 inserted into the anterior and internal surface of the tibia, about 

 the middle of the bone ; the posterior portion is continued to the 

 internal malleolus, and is connected along its posterior border 

 with the deep fascia of the leg. 



C. and L.— 274-5; 285-6; 287-8; 289, fig. 4; 294 (s). 



OUurator externus arises from the outer surface of the obturator 

 membrane, and from the bone beneath. It is inserted into the 

 digital fossa of the femur, anterior to oUurator internus, and 

 somewhat below it. 



Not given in Cuvier and Laurillard. 



OUurator internus arises from the inner margin of the obtura- 

 tor foramen, and is inserted into the digital fossa, posterior to 

 oUurator externus, and by a narrower tendon. 



Not given in Cuvier and Laurillard. 



Adductor magnus takes origin from the os pubis and ramus of 

 the ischium. It is inserted into the back and inner side of the 

 femur for about the middle two-thirds of its length, and by a 

 separate slip into the internal condyle of the same bone.
