This species is a well-known inhabitant of most of the West-Indian Islands, having 
been figured as long ago as 1751 by Edwards* from specimens obtained in the island 
of Jamaica. Upon this figure Linneus founded his description! Vieillot also described 
it from San-Domingo specimens, giving it the name of altilogua’. The Cuban repre- 
sentative of this form has sometimes been admitted to specific rank under the name 
of V. barbatula; so also have those of the Lesser Antilles in several instances been 
provided with names®; but, after examining a considerable series, it seems to us that 
the points of difference are too slight and unstable to admit of any separation being 
satisfactorily made. 
The presence of this Vireo in Continental America has only recently been ascertained. 
M‘Leannan in 1864 sent us a single specimen from Panama which we referred to this 
species ®. ‘This is the only one we have seen from Central America ; and the correctness 
of its determination was questioned by Prof. Baird?. But we have now obtained 
authentic specimens both from Merida® and San Esteban in Venezuela, and from 
Bartica Grove in British Guiana (the latter sent us by Mr. Whitely) ; and neither do 
these nor does our Panama specimen differ from the Jamaican bird. Moreover it has 
now become much more probable that the description by Vicomte DuBus of a bird from 
Ocaiia in Colombia as Vireosylvia frenata was based upon an individual of V. calidris 
captured in its winter quarters. Messrs. Newton ® and Mr. Ober® both suspected that 
the birds observed in St. Croix and Dominica were migrants, arriving in the spring, 
remaining to breed, and departing again before winter; and on this point we have 
recently the positive testimony of Mr. Edward Newton, now residing in Jamaica, who 
assures us that V. calidris is certainly a migratory species in that island. The presence 
of the species on the continent of South America is thus satisfactorily explained; and 
we include V. calidris in this work without further hesitation. The fact, too, of this 
bird being migratory lessens very much indeed the probability of there being any 
distinct island forms.
