BANGS: BIRDS FROM THE CAYMAN ISLANDS. 319 
Some years ago Ridgway separated the Cayman Brac form based on 
specimens collected there by Maynard. Some of Maynard’s skins 
of this bird are in the M. C. Z. so discolored by his chemical preserva- 
tive as to be practically unidentifiable, and I am afraid even Ridgway 
was deceived by them. Specimens in the present collection from 
Cayman Brac are absolutely identical in color as well as in size with 
those from Grand Cayman. In adult males from Grand Cayman 
the wing runs 49-51.5; in adult males from Cayman Brac the wing 
runs 48-51, the tips of the primaries are slightly more worn down in the 
Cayman Brac skins. Birds from the Caymans are as a whole like 
Jamaican specimens, and are slightly different from the average of 
Cuban examples. 
We have now in the M. C. Z. upwards of 150 skins of T. olivacea 
from the Greater Antilles, and after a very critical study of these 
specimens, I think the species might by very close splitting be sub- 
divided. Individual variation, however, is so great and the characters 
that separate birds from the various islands so subtle that the wisdom 
of so doing is very questionable. If subdivided, the forms of the 
Greater Antilles would stand, probably, as follows: — 
Tiaris olivacea olivacea (Linné). . 
Haiti and Santo Domingo. 
Slightly browner olive-green above and on flanks; yellow of throat 
often very pale (the color of the throat-patch is, however, subject to 
much individual variation in all the forms). 
Tiaris olivacea lepida (Linné). 
Cuba and Isle of Pines. 
Inclined to be darker and duller, than are the other forms, the upper 
parts often dull dusky olive-green; the flanks darker and encroaching 
more on belly; belly seldom yellowish. 
Tiaris olivacea adoxa (Gosse). 
Jamaica and the Caymans. 
Usually paler and more grayish olive-green above and on flanks; 
belly paler and often washed with pale yellowish. 
I have no doubt that the subject of Gosse’s plate was a young indi-
