Note on the Skeletons of the Buansu. 21 1 



development of the lateral processes of the numbers and of 

 the spinous processes in the dorsals along with a firmer 

 pelvis, would indicate greater strength of trunk in the dog 

 and jackall than in the buansu. On the other hand, the 

 greater size (and development of ridges) of the bones of 

 the extremities (fore and hind denote more power of limb 

 in buansu than in the other two). The number of vertebrae 

 and ribs in all three the same. Cervicals seven, dorsals 

 thirteen, lumbers seven, ribs thirteen. 



In general conformation the vertebra? are also alike. In 

 buansu, the spinous processes of the sixth and seventh 

 cervicals are longer than in the other. The following are the 

 only appreciable differences on comparing the extremities of 

 these three animals : — 



The scapula is roundest and broadest in the buansu; 

 rounder and broader in jackall than in dog. The crest 

 of the scapula is most largely developed in buansu, and 

 least so in the dog. The fore arm (radius and ulna) is 

 longer in proportion to the humerus in the dog and jackall 

 than in buansu. The carpus and digits united, are longer 

 in proportion to the fore-arm in buansu than in dog or 

 jackall. Thus the humerus and hand are longer in propor- 

 tion to the fore-arm in buansu than in the dog and jackall. 



The relative size of the bones of the pelvis offer no 

 marked differences in these animals. The femur and tibia 

 in all three bear a like proportion to one another. In the 

 buansu the tarsus and toes united bear a greater propor- 

 tion to the length of tibia than in the dog or jackall. If 

 these slightly marked differences are accurate, and if they 

 affect the physical powers of these animals, in the general 

 mode, the buansu is less fleet of foot than the dog or jackall, 

 also less powerful in the spine; but a more active digger, 

 and more fit to scramble and climb in difficult places.
