The scapula is in a damaged condition, the coracoid process being lost. 

 The spine is high, most so at the acromion. The glenoid cavity is lost 

 above the line of the spine; the remaining part has the transverse greater 

 than the vertical diameter, and is very little concave. The tuberosities of 

 the head of the humerus are prominent, especially the great one. The 

 latter does not extend as far posteriorly as in Temnocyon corpphceus, and is 

 obliquely truncated by the teres facet. The proximal border of the great 

 tuberosity is a ridge, but neither tuberosity develops a ridge of the shaft. 

 The anterior face of the latter is rounded. I find this part of the humerus 

 a good deal more like that of Canis than those of Mangusta, Putorius, or 

 Mustela, where the tuberosities continue immediately downwards into an- 

 gular ridges. The shaft of the humerus is lost. The distal portion is pre- 

 served. It resembles that of Mangusta rather than that of Canis or the 

 Mustelidce. It has greater transverse extent both as to the condyle and the 

 epicondyles than in Canis sp., but rather less than in Temnocyon coryphceus. 

 The internal flange of the condyle is well developed, but the radial con- 

 vexity is weak. The olecranar trochlea is narrow, and the fossa is deep, 

 rather narrow and transverse and not double as in some Mustelidce. The 

 proximal parts of the ulna and radius are preserved. The inferior edge of 

 the ulna is turned inwards. The bicipital tuberosity of the radius is well 

 marked, and bounds a fossa which is between it and the head. The latter 

 presents a wide oval to the humerus. The anterior foot of the right side 

 remains attached to the block which contains the pelvis, and from which the 

 right humerus was cut. It includes the proximal halves of the metacarpals 

 except the first, and the magnum, unciforme, and cuneiforme of the carpus.
