various places on Carriacou. I have seen it on Mayreau and Petit 
Martinique, and stray examples at Ashton and Battery Hill, Union 
Island. 
It is common on the lowlands of Grenada. 
Hirundo erythrogastra (Bodd.). Barn Swallow.— Hughes 
( 1750 , p. 73), says: “As the make of this bird every way answers 
the description of those of the same species [H. rustica ] in England 
it would be needless to describe it.” He says further that in the 
winter (?) months “ they retire to their holes in the rocks, and do not 
appear during those months.” 
The Barn Swallow is common in all these islands from August 
until March, appearing in large flocks at Barbados and Carriacou. 
I have seen it on St. Vincent, and on Mustique, Bequia, and Union 
Island among the Grenadines. 
Vireosylva calidris barbadense Ridgw. Monkey-bird ; 
Lady-bird ; Ladies’ Related.— A comparison of the measure¬ 
ments of 23 males and 19 females of this form from St. Eustatius to 
Grenada, including 6 breeding birds from Barbados and 7 from the 
Grenadines (Bequia, Union Island, Prune, and Carriacou), shows 
that, while the individual variation is rather large (largest male, 
wing, 82, tail, 66, culmen, 15, tarsus, 20, Barbados; smallest male, 
wing, 75, tail, 57, culmen, 16, tarsus, 20, Grenada; largest female 
wing, 79, tail, 65, culmen, 15, tarsus, 20, Dominica; smallest female, 
wing, 75, tail, 56, culmen, 16, tarsus, 19, Grenada) it would be 
impossible to divide this form further on the basis of measurements 
alone. I have a male from Carriacou larger than that given by Mr. 
Ridgway (Birds No. and Middle Amer., pt. 3, p. 140, 1904) from 
St. Lucia. My four St. Vincent birds are much larger than the 
three recorded by him, while all the measurements he gives may be 
duplicated in my series of Grenadine examples alone. 
The color of this bird is exceedingly variable; but my series shows 
that it is wholly dependent on the season at which the birds are 
taken. When perfectly fresh, the bird is bright olive green above, 
with sides of the head light gray, the pileum brownish gra}q this 
color distinct from the olive of the back and not grading into it, as 
in V c. calidris , and the under parts white, with the sides, flanks, 
and under tail coverts tinged with sulphur yellow. The feet are 
slaty-blue, and the iris is reddish brown. Mr. Nicoll’s (: 04 , p. 563) 
description and plate of “ Vireo laurae ” refer to a bird of this sub-
