168 Transactions. — Zoology. 



Humerus: Length (including cartilage), 95mm.; bone 

 only, 65 mm. Transverse diameter of bone — Upper end, 

 45 mm. ; lower end, 50 mm. Thickness, 24 mm. 



Eadius : Length along pre-axial side, 75 mm. ; post-axial, 

 60mm. Length of bone only (along its middle), 60mm. 

 Least breadth (along its middle), 30 mm. Thickness, 12 mm. 



Ulna: Total length along post-axial, 63mm.; pre-axial, 

 60 mm. Total length bone (in middle), 55 mm. Least 

 breadth, 26mm. Thickness, 10mm. Olecranon, 25 mm. 



Total breadth at distal end of RU. (including cartilage), 

 80 mm. 



In the 2nd edition of Wall's paper a photograph of the 

 right limb is given, which appears to agree well with the 

 limb of the present specimen, although the bones of the 

 former had to be pieced together, and were not found in 

 situ, so that the cartilaginous parts do not exhibit that 

 characteristic feature above referred to. Wall describes 

 " seven " carpal bones, but it is pretty evident that the 

 "two linear transverse bones" are the distal epiphyses of 

 the radius and ulna, at the ends of which he locates them. 

 The remaining five are accurately shown in the photograph 

 and described in the text. It is a more accurate representa- 

 tion of affairs than the woodcut illustrating Krefft's paper. 

 The figure also seems to show the peculiar prolongation of the 

 cartilage from the radial epiphysis towards the metacarpal of 

 the first digit. The pisiform, however, is not shown.
