BANGS: BIRDS FROM THE CAYMAN ISLANDS. 315 
is absolutely identical with the Bahama bird. All the Cayman 
examples are in the yellow phase of plumage. They correspond 
exactly with yellow specimens from the Bahamas from Inagua to 
New Providence, the type locality of V. crassirostris. The three 
characters that Ridgway in his Birds of North and Middle America 
thought might distinguish V. allenz, all prove illusive. The browner 
back in the specimens he examined was due entirely to discoloration 
from the now famous chemical preservative used by Maynard; the 
outermost primary is not smaller; and the pale wing-bands are not 
broader. 
Todd (Annals Carnegie mus., 1911, 7, p. 428-430) has discussed at 
length the color-phases of V. crassirostris, and I wholly agree with him 
that the gray and the yellow (the so-called Vireo crassirostris flavescens 
Ridg.) specimens, represent nothing but extremes of color-variation 
in one and the same subspecies. 
Examples from the different islands of the Caymans are all quite 
alike. 
MNIOTILTIDAE. 
DENDROICA PETECHIA PETECHIA (Linné). 
Dendroica auricapilla Ridg., Proc. U.S. N. M., Aug. 1888, 10, p. 572, 
Grand Cayman. 
Thirteen specimens, both sexes, adults and two young, Grand Cay- 
man, Little Cayman, and Cayman Brac, April, May, and July. 
This series together with four skins from the Caymans already in 
the M. C. Z. I have compared most carefully with a fine set of 
Jamaican specimens, with the result that I find no way in which to 
separate them. Ridgway in his Birds of North and Middle America 
recognizes auricapilla as differing from petechia on the grounds of 
“decidedly shorter wing and larger bill and feet.”” His own measure- 
ments, however, which followed, show very trifling differences. My 
measurements of eight adult males from the Caymans, the wing is: — 
62-65, (63.81); exposed culmen, 10-11.5 (10.62). Im eight adult 
males from Jamaica, the wing is:— 62-67 (64.5); exposed culmen, 
10-11 (10.68). I can see no differences at all in the feet. 
There are no differences in specimens from the three islands of the 
Caymans. 
Dendroica petechia petechia can be separated from D. p. gundlachi 
Baird of Cuba by slightly paler colors and more extensively ochraceous 
crown.
