2949. An anterior dorsal vertebra. 



A strong metapophysial ridge rises between the diapophysis and zygapophysis : the groove 

 for the nerve is almost converted into a foramen on the right side. 



2950. One of the ribs of the right side. One of the ribs of the left side. 



These are slender in proportion to their length. 



2951. The left humerus. 



It is remarkable for the strength of the tuherosities and deltoid ridge, and for the smooth 

 basal surfaces between the tuberosities and on the outside of the external one. The medullary 

 artery enters the back part of the bone and proceeds obliquely forwards and downwards. 



2952. The radius. 



The surface for the ulna extends along the back part of the ridge bounding that for the 

 humerus. 



2953. The ulna. 



The two bones interlock at their distal end by reciprocally adapted cavities and tuberosities. 



2954. The right femur. 



The head is impressed by a deep semicircular pit at its margin. Ossification has extended 

 along the ligament from the great trochanter to the third trochanter. The rotular surface is 

 distinct from those on the condyles. 



2955. The right tibia. 2956. The right fibula. 



2957. The bones of the fore-foot, with the dried integument and hoofs. 



2958. The dried integument and hoofs, with the ungual phalanges, of the hind 

 foot. 



2959. The germ of a penultimate molar, right side, upper jaw, of the Rhinoceros 

 simus. Presented by Wm. J. Burchell, Esq., F.L.S.
