Kamschatkan Biorhorn 221 



The first of these, a superb snow-white animal, was described by the writer 

 some years ago as Ovis dalli in honour ot Prot. W. H. Dall, the pioneer 

 scientific explorer on the ^'ukon. The specimens upon which my de- 

 scription was based were obtained trom the Fort Reliance country by 

 Mr. L. N. M'Ouesten. DalTs mountain sheep is found over a wide area, 

 from the low hills beyond the tree limit near the Arctic coast south across 

 the Yukon and Kuskoquim to the Alaskan range." 



From this it would appear at first sight that the animal is pure white 

 at all seasons, but the original description shows that this is not the 

 case ; and a mounted specimen in bad condition in the British Museum 

 has traces of pale tawny on the neck and fore-limbs. Hence it would 

 seem probable that the pure white is assumed only in winter, and not 

 always then, since the British Museum example is apparently in the 

 winter coat. Mr. Walter Rothschild has a pure white head from Alaska 

 in the Museum at Tring Park.
