 they were less numerous, due perhaps to their having been incidentally 

 killed by the systematic trapping that had been carried on during the 

 previous winter over much of the ground we covered at that point. 

 At Flood Glacier and Great Glacier, red squirrels were extremely 

 scarce. We realized, of course, the fact that this species occurred as 

 two different geographic races, at the mouth of the Stikine and at the 

 head of the river, respectively, and that there was probably continuous 

 distribution of the species for the entire length of the stream. We 



Pig. X. Thicket of wild cherry (Primus demissa) at Telegraph Creek. This 

 shrub grows in abundance in that region; by the middle of June the bushes are 

 covered with white flowers. The gray-headed chipmunk was characteristically 

 found in such surroundings as are here shown, on rather broken ground that 

 was grown up with bushes of this sort. Photograph taken June 15, 1919. 



realized also that in all probability somewhere near Flood Glacier or 

 Great Glacier was the critical point where the two subspecies meet, 

 and for that reason we bent every effort toward getting specimens 

 from those stations. However, not more than two or three were seen 

 at each place. At Sergief Island, too, red squirrels were scarce. 



Altogether we collected twenty specimens- (nos. 30974-30993), 

 fifteen adults and five young, from the' following localities : Telegraph 

 Greek and vicinity, ten ; Glenora, two adults and one young ; Doch-da-on 

 Creek, three full-grown young ; Flood Glacier, one ; Great Glacier, one ; 

 Sergief Island, one adult and one young. The Telegraph Creek speci-
