Melospiza melodia kenaiensis Ridgway. Kenai Song Sparrow. 
A series of forty-two song sparrows were obtained (nos. 1406- 
1447). These were taken as follows: Hight from Hawkins 
Island, six from Hinchinbrook Island, eleven from Montague 
Island, eleven from Green Island, four from Latouche Island, 
one from Knight Island, and one from the mouth of Port Nell 
Juan. Other localities where the species was seen, but no speci- 
mens taken, were Chenega, Hoodoo, Dise, Eleanor, Naked, and 
Storey islands, and Valdez Narrows. The series consists of 
twenty-eight adults in more or less worn summer plumage, twelve 
half-grown to full-grown juvenals, and two specimens in fresh 
fall plumage which I take to be birds-of-the-year. After careful 
scrutiny I am unable to detect any differences in the specimens 
from island to island. The water-ways between adjacent islands 
are probably too narrow (always less than seven miles) to pre- 
vent frequent crossing, and therefore mingling of strains, even 
in this sedentary and susceptible bird. 
I have not had the opportunity to examine a satisfactory 
series of typical kenaiensis from Cook Inlet, having but two 
examples of the latter at hand (Coll. U. 8. Nat. Museum, nos. 
81380, 81385). The first is a summer adult female; the second 
a juvenal male. The former is less heavily streaked and not 
so slaty as corresponding birds of Prince William Sound; the 
latter is decidedly paler, not nearly so broadly and_ blackly 
streaked. Through the courtesies of the authorities of the Na- 
tional Museum I have at hand eleven specimens of MW. m. cawrina 
from the Yakutat Bay region. From these the Prince William 
Sound birds differ by much greater size (at least equaling 
kenaiensis) and a decidedly leaden, less brownish tone of color- 
ation. The streaking is even more intense and sharply defined, 
not indistinet and blended, as in kenaensis proper. The birds 
of Prince William Sound, therefore, are large song sparrows 
(¢, no. 1443: wing, 78.5; tail, 78.1; tarsus, 23.8; culmen, 13.7), 
with sharply dark-streaked lower parts, and upper parts dis- 
tinetly streaked upon a ground color very dark-toned in the 
direction of leaden gray rather than any shade of brown. I 
should not hesitate to name this as a new subspecies, if more
