1925] Storer: A Synopsis of the Amphibia of California 169 
found at and near Hazelton on the Skeena River and at Telegraph 
Creek on the Stikine River, and is present at Masset, Queen Charlotte 
Islands (specimens in Mus. Yert. Zool.). In southeastern Alaska it 
has been taken at numerous localities north to Prince William Sound 
(Van Denburgh, 1898, p. 139 ; specimens in Mus. Yert. Zool.). Within 
the area indicated, west to the Pacific Coast it is the only species of 
Bufo present. In Colorado it is stated to occur only in the mountains. 
In California it ranges from sea level, as at Eureka, to 8700 feet as 
in Modoc County. In British Columbia and southeastern Alaska it 
apparently occurs only at low altitudes. 
Life-history. — Few data are at hand concerning this subspecies. 
Cope (1883, p. 18) states that at Pyramid Lake, Nevada, in July, 1882, 
toads of this form were “in voice” in a pond near the shore of the 
lake, suggesting breeding at a later date than with halophilus in Cali- 
fornia. The breeding season of boreas in the Rocky Mountains must 
of necessity be later than in the low altitudes in northern California 
and Oregon. 
Reporting the results of a trip to Klamath and Silver lakes, 
Oregon, and the lakes in northeastern California, Cope (1883, pp. 
19-20) said of this toad: 
It is especially numerous at Klamath Lake, where it covers the basaltic blocks 
which lie partially in the water, concealed by the Typhae, which grow from the 
bottom. They accumulate there in large piles, sometimes as large as a bushel- 
measure, and afford abundant food for the Eutcenice which are scarcely less abun- 
dant. One specimen of this toad was as large as the average Bufo marinus of 
Brazil, and a specimen seen at Warner’s Lake was but little smaller. 
Coues and Yarrow (1878, p. 289) say that in Montana “specimens 
were taken from the stomach of Salmo namaycush and other fish of 
the same genus in this locality, further indicating its aquatic nature.”
