ones from Little Cayman and Cayman Brac taken in June and July. 
Brown took fully fledged young from July 10 to July 28. The wing 
in\the adults in this series ranges, in Grand Cayman skins, from 103- 
107; in skins from Cayman Brac, 97-103; in the only adult from 
Little Cayman (a o’) it is 108. The Cayman Brac specimens have 
the tips of the primaries a little more worn down than the Grand 
Cayman ones. 
MYIARCHUS SAGRAE SAGRAE (Gundlach). 
Myiarchus denigratus Cory, Auk, Oct. 1886, 3, p. 500, 502, Grand 
Cayman. 
Ten specimens, both sexes, all adult, Grand Cayman, April and May. 
Apparently this bird is found in Grand Cayman only of the Caymans. 
The specimens in the present series are indistinguishable in any way 
from Cuban skins. 
* ELAENIA MARTINICA CAYMANENSIS Berlepsch. 
Elaenia martinica complexa Berlepsch, Proc. 4th International 
ornith. congress, 1905, p. 395, Cayman Brac. 
Twenty-six specimens, both sexes, all adult, Grand Cayman, 
Little Cayman, and Cayman Brac, April, May, June, and July. 
Specimens in exactly similar plumage from the three islands of the 
Cayman group are absolutely alike, and no subdivision can be made. 
I am sure Berlepsch was deceived by the artificial discoloration of 
Maynard’s Cayman Brac skins, upon examples of which he based 
his E. m. complexa. Two such skins are now before me and I do not 
wonder at such a mistake being made. 
The Cayman Elaenia fades and bleaches out late in summer, 
losing all its colors. Two skins collected in Grand Cayman in 
August, 1886, by W. B. Richardson, have lost all traces of the colors 
and markings of the form when in fresh plumage. The April speci- 
mens in the present series from Grand Cayman are in beautiful fresh 
unfaded plumage. Some of the late July skins from Cayman Brac 
have nearly completed the postnuptial moult and are indistinguish- 
able from these. Others taken at the same time had not commenced 
to moult, and are nearly as faded out as the August examples just 
referred to. 
The Cayman bird appears an excellent form, but I cannot agree with
