externally, their medullary cavities are distinct. The canal of the medullary artery enters 

 the back part of each, above the middle, and ascends obliquely to its respective cavity. 



3470. The ossa innominata. 



They are confluent at the symphysis pubis. The tuberosities of the ischia are divided into 

 a posterior and an external prominence. 



3471. The left femur. 



The medullary arterial canal enters at the back part below the middle of the shaft and 

 inclines obliquely upwards. Below this orifice there is a strong rough protuberance. 



3472. The right femur, longitudinally bisected. 3473. The left tibia. 



3474. The right tibia, longitudinally bisected. 



3475. The left metatarsus. 



It is remarkable for the strong pointed process which rises from the back part of the 

 proximal end. 



3476. The right metatarsus, longitudinally bisected. 



It shows the complete double septum which divides the medullary cavities of the two co- 

 alesced bones. The arterial canals have the same position and course as in the metacarpus. 



3477. The right astragalus and calcaneum. 



The fore part of the astragalus is less equally divided into two facets than in the ordinary 

 Ruminants. 



3478. The left astragalus and calcaneum. 



3479. The skull of the female Camel (Camelus bactrianus}. 



The last true molar in the upper jaw has not risen into place, and the deciduous canines 

 have not been shed: the pair of laniariform upper incisors and premolars (p 1) are just 

 emerging : the molariform premolars ( p 3 and p 4) are not quite in place. In the lower jaw 

 the last deciduous molar is not shed, although the last true molar has nearly risen into place. 

 The deciduous canines are still retained, and only the first pair of permanent incisors are fully 

 developed.
