DENDROICA. Dike 
pendicular to the shaft, the patch covering the posterior two-fifths of 
the feather; on the 3d feather it is confined to the tip. The yellow 
stripe to the eye is continued a short distance beyond it, but becomes 
white. 
It is quite possible that mature spring male specimens have the 
middle of the back streaked with dusky, as in D. graciz and 
townsendit. 
This interesting new species of Warbler has several peculiarities 
of form which almost entitles it to rank as a type of a separate 
genus. The anterior toes are very short, quite like Parula, which 
also it resembles somewhat in coloration, but the wings are too 
short, and the bill not conical enough. In fact, bill and feet are 
much as in Dendroica maculosa. The wings, however, differ in 
being much shorter, less pointed, and more rounded. The tail, also, 
is much rounded. The nape shows quite a number of long bristles, 
with fibrille at the end, which I have not noticed elsewhere among 
the Warblers. ; 
The relationships of the species, as far as coloration is concerned, 
are to D. gracizx, Coues, and D. dominica, as shown in the preceding 
article. 
I have much pleasure in dedicating this new species to the 
daughter of Mr. Robert Swift, of St. Thomas, a gentleman to whom 
the Smithsonian Institution is indebted for a very important collec- 
tion of the birds of St. Thomas and Porto Rico, made solely at his 
expense, to be used in preparing the present work.
