A NEW SUBSPECIES OF RED-WINGED BLACKBIRD 
FROM WESTERN CENTRAL AMERICA. 
BY A. BRAZIER HOWELL. 
Among a collection of birds which was made by A. van Rossem 
in Salvador, during 1912, are five red-wings —four males and a 
female — which prove to be of a form heretofore unnamed. I am 
indebted to H. W. Henshaw of the Bureau of Biological Survey, 
and to D. R. Dickey, for the loan of specimens that were necessary 
for working up this material. The series of Agelaius p. richmondi 
used in making the comparisons, comprise skins from the states of 
Vera Cruz, Tabasco, and Yucatan, Mexico. Those of A. p. sono- 
riensis are from the Imperial Valley, and the Lower Colorado 
River in California. 
Agelaius phoeeniceus grinnelli, new subspecies. 
GRINNELL’S RED-WING. 
Type.— Male adult; no. 1585 coll. A. B. H.; San Sebastian, Salvador, 
July 18, 1912; collected by A. van Rossem. 
Driaaenosis.— From richmondi, the males differ in being larger, espe- 
cially the wings; the culmen is slightly shorter, but the bill is much heavier, 
thicker, and deeper. The length, taken in the flesh, is about the same as 
that of sonoriensis, but wing and tail are shorter, especially the former, 
while tarsus, middle toe with claw, and culmen are longer, the bill being 
also heavier, thicker, and deeper. The wing formula agrees with the usual 
one of richmondi (ninth primary shorter than fifth), as opposed to that of
