18 Howe, Ranges of Wilson's and Willow Thrushes. Boake 
Jan. 
The loral and auricular regions are quite rich green. Jugulum and lower 
throat abruptly joining white above and black below, rich ochraceous buff. 
The frontal processes are much more developed than the one shown 
inthe splendid figure in Ridgway’s ‘ Manual,’ its anterior outline at a 
right angle with the line of the tomium, the farthest. point from tomium 
being 38 mm., its greatest width 27 mm., its least width 18 mm., while 
the greatest depth of bill is 17 mm. The other Drake shows respectively 
34, 24, 17 and 18 mm. 
Though the birds were reported at the close of December, they 
spent the winter at the place secure from the various strategies 
used to approach them, or lure them within shot of the shore, and 
so it was the beginning of April before they came into the hands 
of this expert collector. ‘This was due to the fact that the depth 
of water required to yield their favorite food, —which upon dis- 
section proved to be young holothurians (fentfacta froudosa) , — 
kept them farther from the shore than Somateria dresseri is accus- 
tomed to feed, and this animal being abundant at their chosen 
spot, they would not condescend to approach decoys as S. dessert 
did. 
According to Hagerup, S. spectabilis habitually feeds in deeper 
water than that required by Somaterza mollissima borealis in Green- 
land where both species are abundant (Birds of Greenland, 
p. 19).

LOCICHLA FUSCESCENS, SALICICOLA IN 
NORTH AMERICA. 
BY REGINALD HEBER HOWE, JR. 
WuIiL_E looking over the Ornithological Collection of the Mu- 
seum of Comparative Zodlogy, I came across a peculiar specimen 
of Wilson’s Thrush (Aylocichla fuscescens) taken at Newport, 
Rhode Island, by R. L. Agassiz on the very late date for this 
locality of September 25, 1885. A few days later I happened to
