CLARK: LESSER ANTILLEAN BIRDS.

also ( Amazona imperialism A. bouqueti , A. versicolor, and A. guil- 
dingii) are related to A. vinacea of South America, while those of 
the Greater Antilles (except A. agilis and A. vittata ) belong with 
A. albifrons of Central America. 
Two of the Lesser Antillean species (and genera), Sericotes holo- 
sericeus and _ Bellona exilis , as mentioned above, have habitats over¬ 
lapping Greater Antillean territory, while with other species the 
reverse is the case. These latter are Poecilonetta bahamensis 
(south to Guadeloupe), Pendrocygna arborea (south to Antigua), 
and Phoenicopterus ruber (Anegada, and formerly Antigua and 
Guadeloupe). 
The islands whose avifauna forms the basis of the present paper 
(Barbados, St. Vincent, the Grenadines, and Grenada) are perhaps 
the most interesting of all the Lesser Antilles. Barbados, like the 
Bahamas, is oceanic, while the others show the diminishing intensity 
of the West Indian fauna as we go southward, correlatively with 
the increasing number of South American forms. 
In the discussion of the avifauna of St. Vincent, the Grenadines, 
and Grenada, the first thing that claims our attention is the South 
American element. Trinidad has, according to Chapman, 199 resi¬ 
dent land birds, all of which are continental, or closely related to 
continental forms. On Tobago we find 65 resident land birds, all 
but 6 of which occur (or have closely related forms which occur) on 
Trinidad; but these 6 (including Mimus gilvus and Ortalis ruji- 
cauda 1 ) are all of South American stock, some of which may yet be 
found in Trinidad. Grenada has 13 birds common to it and Tobago, 
and all but one of these ( Mimus gilvus) common to it and Trinidad, 
while three others ( Calospiza cucullata, Troglodytes grenadensis, 
and Merida nigrirostris) are localized forms from purely South 
American stock. 2 On the Grenadines there are only 8 of these con¬ 
tinental birds, viz .: Merida gymnophthalma, Sporophila gutteralis, 
Mimus gilvus , Elaenea martinica flavogastra, Molothrus atro- 
nitens , Tyrannus melancliolius satrapa , Myiarchus tyrannulus 
tyrannulus, Muscivora tyrannus, while Chaeturapoliura, Calospiza, 
Merula nigrirostris, and Troglodytes are lacking, although all four 
reappear on St. Vincent. 
1 Claimed by some to have been introduced from Venezuela, although origi¬ 
nally described from Tobago. 
•Troglodytes occurs northward to Guadeloupe; Calospiza and Merula nigri¬ 
rostris are found also on St. Vincent.
