DESCRIPTIONS OF THE NEWFOUNDLAND OTTER 

 AND RED FOX. 



BY OUTRAM BANGS. 



The following descriptions of the otter and the red fox of New 

 foundland are based on material collected by Ernest Doane, 

 now in the Bangs collection. Of the otter, he has sent a fine pair 

 of adult skins with skulls, and two extra skulls; of the fox, six 

 skins with skulls, and nine extra skulls. In addition to these I 

 have examined a large series of unsexed otter skulls from New 

 foundland in the Museum of Comparative Zoology at Cambridge.
