The left fore-limb is quite completely preserved, and, as observed 

 above, is longer in proportion to the length of the skull than in Linino- 

 cyon. The scapula is long and rather narrow, more nearly recalling such

a recent form as Viverra zibetha, the coracoid process and the meta- 

 cromion being, however, proportionally more developed than in the 

 latter. The spine, which is very high, rises close to the glenoid cavity 

 and separates the pre- and post-scapular fossae in nearly equal pro- 

 portions. 



The humerus has received considerable crushing, especially in the 

 upper portion of the bone, but its length is not impaired. The bone

 the shaft, but does not terminate as abruptly below as in the Miacidas. 

 The entepicondyle and entepicondylar foramen are quite large, 

 having approximately the same proportions as in Limnocyon veriis. 

 The trochlea is also similar to the latter, except the inter-trochlear
