The following are parts of the same skeleton of a kind of Mule, called ' Kumrah ' : 



Presented by the Right Hon. Earl Granville. 



3238. The skull. 



It has all the essential osteological and dental characters of the genus Equus, but the facial 

 part of the skull is unusually short. The alveolar portions of the upper jaw have been 

 diseased, and the teeth are distorted and unequally worn. 



3239. Five of the dorsal vertebrae. 



In these may be traced the progressive change of position of the metapophysis from the 

 diapophysis in the first vertebra to the zygapophysis in the last. 



3240. The last dorsal and first four lumbar vertebrae. 



The diapophysis of the dorsal vertebra is short, and supports an articular surface for the 

 last rib. Its homotype in the next vertebra is suddenly elongated, and probably increased 

 by a coalesced or connate rudiment of a lumbar rib. In the last lumbar a posterior articular 

 process is developed from the back part of each diapophysis. In all these vertebrae the cen- 

 trum shows a hypapophysial ridge. 



3241. The last two lumbar vertebrae, the sacrum, and the five anterior caudal vertebrae. 



The diapophysial articulations are developed in the lumbar vertebrae as in other equine 

 animals. The sacrum includes five vertebrae. The diapophyses and metapophyses continue 

 to be developed from the caudal vertebrae after the zygapophyses have disappeared. 



3242. The right scapula. 3243. The left humerus. 



3244. The right radius and ulna, coalesced. 



3245. The principal metacarpal and the two rudimental metacarpals of the right 

 fore foot. 



3246. The ossa innominata. 



The post-pubic depression is more marked than in the ordinary Mule, or the Ass. 



3247. The right femur. 



It shows the third trochanter and the deep fossa above the external condyle, characteristic 

 of the genus Equus.
