more obtuse and directed inwards. The shaft is thus subtriangular in 

 section. The distal extremity is nearly at right angles to the axis of the 

 proximal, and is much expanded transversely. A large part of this expan- 

 sion is caused by the truncate internal tuberosity, and by the less prominent 

 external one. The latter is continued in a thin ala, which only sinks into 

 the shaft at its middle. The condyles are small, the external the most 

 prominent. There is a shallow olecranar fossa, and no coronoid, and hence 

 no supercondylar foramen. There is a large arterial foramen above the 

 internal tuberosity. 



The ubia is compressed, and contracts rapidly towards the distal ex- 

 tremity. The olecranon is broad and obtuse and the humeral cotylus 

 oblique to the long axis. The coronoid process is low. The shaft is 

 curved from right to left (inwards), perhaps by distortion. The radius has 

 a discoidal head with central depression, and it was evidently capable of 

 complete rotation. It exhibits a tuberosity and slight flexure below the 

 head. The distal extremity has a horizontal triangular section with the 

 apex internal and truncate; the shaft near it is quite flat. The carpal articu- 

 lation is a simple, shallow concavity. 



The left ilium is obspatulate and flat, widest at the convex crest, and 

 slightly concave on the outer side. It is rather thin, and the impression for 

 the sacral diapophyses is elongate. The inferior border thickens gradually 

 to the acetabulum; the superior is excised so as to form an open concavity. 



The right yewwr is remarkable for its length. Its shaft is flattened from 

 before backwards, and without flexure. The great trochanter is large, and 

 embraces a deep in-looking fossa. There is a flat tuberosity (third tro- 

 chanter) looking outwards just below, and the little trochanter is a little 

 below opposite to the latter. The condyles are subsimilar in size, the 

 trochlear surface wide, but not flat, and the inner border thickened and 

 considerably elevated. The femur is 1.75 times as long as the humerus; 

 it was scarcely longer, though a small piece is wanting from the shaft of 



our specimen.
