202 REVIEW OF AMERICAN BIRDS. [PART I. 
I have before me a St. Croix skin kindly lent by Mr. Newton, 
and one from St. Thomas, from Mr. Lawrence’s collection, and 
have examined other St. Thomas specimens in the museum of the 
Philadelphia Academy. None of these, unfortunately, are in that 
perfection of feather and coloration necessary to exhibit their true 
character, and I am unable to indicate these features properly, 
though believing them to be different from petechia. 
The St. Croix bird, which resembles petechia in the yellow edges 
to the wing coverts, is smaller, with considerably shorter wings 
proportionally (2.40, instead of 2.65); the wing formula is quite 
different, being 3. 2. 1. 4.5.6, instead of 3.4.2.5. 1.6—the’ Ist 
quill being thus longer than the 4th and 5th, the 2d next to the 
longest, instead of the 1st being shorter than the 4th and 5th, and 
the 4th second in length. The St. Thomas specimens have much 
the same wing formula—=3. 2. 4. 1. 5. 6 in most; in two, 3. 4. 2. 1.5. 6; 
they are rather larger, however, with more yellow on the tail. 
A specimen, in poor condition, obtained in Barbadoes by Mr. 
Gill, and preserved in alcohol (No. 33,766), although apparently an 
adult male, is of very small size: length, 4.30; wing, 2.25; tail, 
2.00; and has as the wing formula, 3. 4.5.2.1. The tail has almost 
the same amount of yellow as in D. exstiva, and much more than in 
any of its red-capped allies, viz., the entire inner webs of five ex- 
terior feathers, with exception of a terminal streak. On the outer 
web of the exterior feather the basal yellow does not extend quite 
as far up as in estiva. The entire top o: head is of a deep chestnut- 
brown. This bird, therefore, may be a different species again from 
those just referred to. The specimen exhibits the unusual anomaly 
of having seven tail feathers on one side, and six on the other. 
The solution of all the questions connected with this subject will 
depend upon full series of specimens in perfect spring plumage, from 
all the different West India Islands. It is, however, quite evident 
that, while D. petechia, of Jamaica, and D. gundlachi are distinct 
species, there is at least one, and perhaps several additional species 
in the West India Islands more to the eastward, perhaps one for 
each group of islands. 
Norr.—As the present pages are passing through the press the 
Institution has received a series of Golden Warblers from St. 
Thomas, collected by Mr. Swift, which, unfortunately, being in 
winter plumage, do not furnish the means of making a final com- 
parison, though substantiating what has already been said in regard 
to the character of the wings.
