166 NORTH AMERICAN FAUNA. [NO. 27. 



son, who undoubtedly collected the type specimen, states that the 

 species was found only at that locality, where it made its appearance 

 about three weeks later in the spring than Richardson's ground 

 squirrel. 



In notes sent to Dr. C. Hart Merriam by John Macoun some years 

 ago he states that this species was observed at Athabaska Landing. 



Citellus (Ictidomys) tridecemlineatus (Mitchill). Thirteen-lined Sper- 



mophile. 



This species is abundant locally along the road from a few miles 

 north of Edmonton, Alberta, to Athabaska Landing. The animals 

 usually frequent open uncultivated fields, but frequently were seen 

 running across the road in the poplar-covered tracts. 



Besides a specimen or two taken by us near Sturgeon River on our 

 spring trips through the region the Biological Survey collection con- 

 tains specimens collected by J. Alden Loring at Edmonton in Sep- 

 tember, 18 ( .)4, and others taken by G. F. Dippie at Edmonton and 

 Red Deer, Alberta, in September, 181)0. Three adults from Edmon- 

 ton average: Total length '287, tail vertebrae 101, hind foot 39. 



Richardson redescribed this species under the name Arctomys 

 (Spermophilus) hoodii, from Carlton House. He gives the north- 

 ern limit of its habitat as latitude 55°, but assigns no definite lo- 

 cality. 6 



Citellus (Callospermophilus) cinerascens (Merriam). Northern Mantled 



Spermophile. 



This species is a rather common inhabitant of the mountains of 

 western Alberta. It was first recorded from there under the name 

 Arctomys (Spermophilus) lateralis, by Richardson, who states that 

 Drummond obtained several specimens " on the Rocky Mountains, in 

 latitude 57°," probably in the Jasper House region.' 



In 1895 J. Alden Loring took two specimens at Jasper House on 

 August 27, and thinks that the species hibernated t soon afterwards. 

 In 1896 he found the species in the mountains 15 miles south of 

 Henry House in July, taking a number of specimens, and in the 

 early autumn noted it as rather common north of Jasper House, where 

 it inhabited rock slides and grassy slopes. He collected specimens on 

 Grand Cache River at points 60 and 70 miles north of Jasper House

 connection with specimens collected by Drummond in the Rocky Mountains. 

 is incorrect, and much confusion has resulted from this statement of latitude 

 being taken literally. The most northern point reached by Drummond was 

 probably short of latitude 55°. (See itinerary of Thomas Drummond, p. 60.)
