CLARK: LESSER ANTILLEAN BIRDS.

Dominica, one from St. Lucia, two from St. Vincent, and three 
from Grenada. 
I have reviewed the matter very carefully with a series of 68 
skins from the West Indies: 4 from Dominica, 7 from St. Lucia, 17 
from St. Vincent, 34 from the Grenadines (Bequia, Mustique, May- 
reau, Union Island, the Tobago Keys, Prune Island, and Carriacou), 
and 6 from Grenada. These were compared with 21 specimens of 
true M. t. tyrannulus from Colombia, and three from Margarita 
Island, Venezuela, making in all 92 examples. 
I have been unable to find any characters by which birds from 
Grenada, the Grenadines, or St. Vincent may be distinguished from 
continental specimens. There is no difference in size. The extent 
of the white markings on the wings is variable, for some birds from 
the Grenadines (agreeing with others from Colombia) have almost 
no white at all, while in others the bands are very wide. In the 57 
birds from St. Vincent, the Grenadines, and Grenada, the rufous on 
the upper tail coAmrts is very conspicuous, more so than in the four 
from Dominica. In fact, in the living bird, as I am acquainted with 
it in these islands and on the mainland, it is a prominent character¬ 
istic. The colors of the head, back, and underparts are identical 
in birds in the same state of plumage from these islands and from 
Colombia. 
The only character I have been able to discover by which speci¬ 
mens from the continent might be distinguished from others from 
Grenada, the Grenadines, or St. Vincent, is the extent of the brown 
markings on the tail. In examples from these islands the brown 
encroaches on the rufous of the inner web for an area just equal in 
extent to the outer web; that is, the brown area is the same on each 
side of the quill; on the outer it occupies the entire outer web, and 
on the inner a space just equal to it. As a general rule, the brown 
on the rectrices of continental specimens encroaches somewhat more 
on the rufous of the inner web; but this is not at all constant, one 
of the birds from Margarita Island having; less brown than most of 
the Grenadine examples. 
As in all other ways continental and insular (St. Vincent, the 
Grenadines, and Grenada) birds are identical, I am forced to consider 
them all as typical M. t. tyrannulus , and to treat the form as one 
which has worked its way up the islands from the continent as far 
as St. Vincent, in the same way that Mimus gilvus , Molothrns
