140 BIRDS OF THE WEST INDIES. 
Adult male specimens of Falco dominicens’s from San Domingo have less 
bands on the outer tail feathers than Florida birds (4. sfarverzus). The San 
Domingo bird is also larger and the black marking on the inner web of the first 
primary does not, as a rule, reach the edge of the feather. In Cuba, Fako sparve- 
rivides is represented by a light and a dark phase of plumage, which is not the case 
with /. dominicensizs from Haiti and San Domingo. 
The dark phase is very different from other species, but the light phase 
somewhat resembles some specimens of /* domdnicens?s; it is distinguishable, how- 
ever, from that species, the Cuban bird being smaller and having less buff or pale 
rufous on the breast, besides other slight differences. In Cuba, the light and dark 
birds breed together, and we are informed that birds of both colors have been taken 
from the same nest. 
The specimens examined are from the following localities : — 
Falco sparverius, 29, Florida; Falco dominicensis, 46, Haiti and San Domingo; 
DE sparvertovdes (light phase), 11, Cuba (dark phase), 24; ako caribbearum, 68. 
Mr. Ridgway considers sfarverioides to be a synonym of domznzcensis, Auk, 
Patio toon: 
41. Strix furcate Temm. The white secondaries which is one of the 
characters by which this form is distinguished is not a constant character. Birds 
from Cuba show much variation in the markings of the secondaries and tail. The 
most extreme example of this form which I have seen is labelled “Cayman Brac, 
W. I.” It is very pale and small and has the tail and secondaries pure white. 
Cuban and Jamaica birds sometimes have the barred tail and mottled secondaries. 
42. Asto grammuicus (Gosse), Pseudoscops grammicus. Birds of the West 
Indies, p. 188, 1889. 
43. The variation in color shown by series of Burrowing Owls from the 
Bahama Islands is considerable; but it is perhaps as well to consider them all the 
same as the Florida form, Speotyto cuntcularia floridana. 1 at one time separated 
the Inagua bird (Speotyto cunicularia bahamensis, Cory, Auk, p. 348, 1891); but 
the supposed differences have since proved to be inconstant. Speotyto cunicularia 
domunicenses, recorded by Northrop from Andros Island, should be referred to 
floridana. 
44. Speolyto cunicularia dominicensis Cory, resembles .S. c. floridana, but is 
apparently a fairly good subspecies. Slight variation in general color, feathered 
tarsus, and difference in marking of under wing-coverts are the principal characters.
