2063. The left scapula. 



The lower division of the acromion is more produced and curved than in the Acouchy. 



2064. The left hurnerus. 



It shows the large intercondyloid perforation, and the sharply defined borders of the tro- 

 chlear joint. 



2065. The left radius and ulna. 



They are in close contact, but are not anchylosed. 



2066. The bones of the right fore-foot. 



The first row of carpals is formed by the scapholunar, the cuneiform, and a large pisiform. 

 There is a supernumerary ossicle in the second row, between the os magnum and trapezoides, 

 which answers to the smaller division of the scaphoid in the Orang and Turtle. The pollex 

 is shorter than in the 'Acouchy : only its metacarpal is here preserved. The fifth finger is 

 much reduced in size, but has the normal number of phalanges. The ungual phalanges are 

 notched at their apex. 



2067. The bones of the left fore-foot. 2068. The two ossa innominata. 



2069. The left femur. 



A fabella is attached to each condyle. The third trochanter is better marked than in the 

 Acouchy. The orifice of the medullary canal is beneath the small trochanter. 



2070. The right femur. 2071. The right tibia and Ebula. 



2072. The bones of the right hind-foot. 



The entocuneiform has coalesced with the proximal end of the second metatarsal, here the 

 innermost. There is an accessory ossicle beneath the joint of the astragalus with the sca- 

 phoid. The scaphoid sends a long and strong process to strengthen the plantar side of the 

 tarsus, but this is not a distinct ossicle. There is a distinct sesamoid beneath the joint of the 

 cuboid with the fourth metatarsal, here the outermost. It might be viewed as a rudiment 

 of the fifth metatarsus, here otherwise absent. There are strong trochlear sesamoids beneath 

 the joints of the metatarsals with the proximal phalanges : the ungual phalanges are notched. 



2073. The bones of the left hind-foot.
