40 NORTH AMERICAN FAUNA. [no. 19. 



and oenoral l)uliy appearance are more like eolumhlensh. Its skull 

 is quite distinctive, the large audital bulke and broad nasals being- 

 unequaled in the group. It seems probable that it is a northern 

 form of hah'di not related to columhum^if^^ which is nearer to vxixhrixj- 

 toni. There are no specimens availal)le to show whether or not it has 

 any connection with dalli^ which is the form found on the Lower 

 Yukon. But two specimens were secured — the type, which I shot in a 

 Lejxirgyrcea thicket at Caril)Ou Crossing, and one very young female 

 which Dr. Bishop took in a willow bog near Bennett City. It seems 

 to have been a decidedly 'off year' for rabbits, for these two were the 

 only ones we saw on our entire tY\\), though numerous signs of their 

 former abundance were seen daily.

 This rabbit is doubtless abundant at certain times all along the 

 Lower Yukon, but we heard very little of it. It is subject to epidem- 

 ics and frequently becomes locally extinct, which probably accounts 

 for its scarcity last year.

Signs of Arctic hares were occasionally noticed about St. Michael, 

 but we did not sec any of the animals. The Eskimos were hunting 

 continually, and brought numbers of ducks and geese to the village to 

 sell, but they brought no rabbits during our stay.

The Canada lynx is not as common in the interior of Alaska as might 

 be expected. I saw no signs of it and could obtain only very scanty 

 information as to its occurrence. The police sergeant in charge of the 

 station at the foot of Lake Lebarge told me that the tracks of but 

 one had been seen in that vicinity during the previous winter. Lynxn 

 skin robes are in common use in the country, but the majorit}^ of them 

 are imported. This I learned from a trader at Circle, who had scA'cral 

 for sale that came from eastern and southern Canada. 



Lynx skulls from the following localities arc in the National 

 Museum: Tanana River, Russian Mission, Nulato, Andraefski, and 

 mountains near Unalakleet. 



Canis occidentalis Richardson. Wolf. 



The country along the Yukon is not well suited for wolves, and they 

 are seldom seen there. A prospector showed me the skin of a large 

 gray one from the upper waters of the MacMillan river — the only 

 one I saw on the trip.
