The measurements may require some correctiou in respect to the 

 supraorbital width, where the cranial walls have suffered from coini)res- 

 siou. The frontal of one side has been pushed so as to overlap that of 

 the other by about au inch. 



The scapula is of a sub-triangular form, the front being vertical, the 

 apex directed backwards and an angle upwards. The posterior expan- 

 sion is considerable, as in the elephants, while the superior angle is 

 acuminate and much produced and massive. The spine is ujuch elevated, 

 bounding a deep supraspinous fossa. It is truncate in front, descending 

 to near the border of the glenoid cavity. Its extremity is dilated in 

 alate fashion, equally fore and aft, and not posteriorly only as in the 

 el#i)hants. The glenoid cavity is flattened so as to be longitudinal, and 

 the coracoid is a rudimeutal tuberosity.

The interior side of the scapula is strongly convex by the develop- 

 ment of two longitudinal ribs, one corresponding to each fossa, but con- 

 cave in longitudinal section. 



The proximal end of the radius exhibits two facets oblique to each 

 other, the larger concave and transverse, the other oblique downwards. 

 Transverse width M. 0.130 ; vertical .070. The extremity of a humerus 

 not found with this individual, to which the radius applies pretty well, 

 has a very oblique trochlear face, and measures seven inches across the 

 condyles. It, however, belongs to a smaller species. 



The femur is entire. Like that of other species of the group it is 

 much expanded proximally and deep distally, with the shaft contracted 

 and somewhat flattened in the plane of the great trochanter. The lat- 

 ter is in one plane, with its external margin turned a little backwards. 

 The head is part of a globe, and is a little more elevated than the tro- 

 chanter, and separated from its apex by a shallow concavity. There is 

 no little trochanter. The trochlear face is not elevated nor wide, and 

 with lateral borders subequally developed. The antero posterior axis 

 of the condyles is somewhat oblique to a line at right angles to the 

 proximal end. On this account the interior condyle is the longer; its 

 articular face is continuous with the trochlear, with a marginal notch ; 

 the outer condyle is continuous, with continuous outer margin. Strong 

 ridges revolve from above the condyles to theposterior faceof the shaft, 

 the inner near the condyle. The outer runs parallel to the main axis as 

 a h)w external ala, and backwards three inches above the condyle. The 

 luce between the ridges is concave.
