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 Aveeks 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 Avas observed at Athabaska Landing. 



Citellus (Ictidomys) tridecemlineatus (Mit chill). 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 frequenth^ were seen 

 running across the road in the poplar-covered tracts. 



Besides a specimen or tAvo taken by us near Sturgeon RiA^er on our 

 spring trips through the region the Biological SurA^ey collection con- 

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

 tember, 189^1:, and others taken b}^ G. F. Dippie at Edmonton and 

 Red Deer, Alberta, in September, 1899. Three adults from Edmon- 

 ton aA^erage : Total length 287, tail A^ertebrse 101, hind foot 39. 



Richardson redescribed this species under the name Arctomys 

 (Sjyei'mojyhUus) liood'tU from Carlton House. He gives the north- 

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

 cality.^ 



Citellus (Callospermophilus) cinerascens (Merriam). Northern Mantled 

 Spermophile. 



This species is a rather common inhabitant of the mountains of 

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

 Arctomys i^&'permo'philus) lateralis^ by Richardson, Avho states that 

 Drummond obtained several specimens " on the Rocky Mountains, in 

 latitude 5T°," probably in the Jasper House region. 



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

 August 27, and thinks that the species hibernated soon afterAvards. 

 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 RiA^er at points 60 and 70 miles north of Jasper House

c Ibid., p. 175, 1829. Latitude 57° of Richardson, frequently used by him in 

 connection AA'itli specimens collected by Drummond in tlie 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.)
