CLARK: LESSER ANTILLEAN BIRDS. 
225 
The first three, while not primarily West Indian, are more or less 
characteristic of that region, and their absence from Grenada is 
noteworthy. Chaetura acuta is Lesser Antillean (Guadeloupe to 
St. Vincent). The crested hummingbird of St. Vincent is Bellona 
exilis (Porto Rico to St. Vincent) ornata (St. Vincent) instead of 
B. cristatus of Grenada, the Grenadines, and Barbados. Amazona 
guildingii of St. Vincent also connects that island with those to the 
north, being closer to A. imperialis of Dominica than to any other 
species. There is no good evidence that any parrot ever existed on 
Grenada. 
The avifauna of St. Vincent shows a correlation with that of 
Grenada ; in each island Calospiza occurs, the two species ( C. versi¬ 
color and C. cucullata ), although perfectly distinct, being closely 
related; both islands have dimorphic species of Coereba that occur 
in the normal coloration of the genus, and also entirely black ( C. 
atrata and C. wellsi) ; and both have closely related subspecies of 
Pyrrhulagra noctis. 
Now those forms common to St. Vincent and the islands toward 
the north, but not occurring on Grenada, viz., Eulampis, Cinchler- 
minia, Cinclocerthia, Myadestes, Cypseloides, Amazona, Chaetura 
acuta, Elaenea martinica martinica , and Bellona exilis are, with 
the exception of the two last, inhabitants of the high woods, these 
two only occurring both there and in the lowlands. Moreover, 
Elaenea martinica martinica is only found in the northern and 
middle parts of the island, and is absent from the region about 
Kingstown. 
The forms common to St. Vincent and Grenada (viz., Elaenea 
martinica flavogastra , Mimus gilvus , Merula gymnophthalrna, 
Pyrrhulagra noctis , Sericotes holosericeus, and Myiarchus tyran- 
nulus tyrannulus ) are primarily lowland species, and Elaenea mar¬ 
tinica flavogastra, Merida gymnophthalma, and Mimus gilvus are, 
the two first entirely, and the last largely, restricted to the Kings¬ 
town valley. Merula nigrirostris , the black form of Coereba 
atrata, Calospiza, and Allenia albiventris occur very generally on 
the island, but all are rare in the high woods. Troglodytes musi- 
cus (which is nearer T. mesoleucus of St. Lucia than to T. grenaden- 
sis) occurs everywhere. 
Thus we find that faunally St. Vincent is divisible into two 
regions, the higher altitudes, and particularly the vicinity of the
