242 Todd. Bahaman Species of Geothlypis. |_April 



differences exhibited are much more striking than in the males, 

 although of a parallel kind. The female of G. rostrata is dull 

 yellow — nearly straw yellow — below, fading to dull white on 

 the abdomen, the sides and flanks shaded with pale grayish or 

 buffy olive — all with an obsoletely streaked appearance, the 

 general effect being much as in some immature specimens of 

 Dendroica striata, except for the dull yellow under tail-coverts. 

 The female of G. maynardi, on the other hand, is much brighter 

 yellow below, the belly paler, more buffy, the sides and flanks 

 darker, the general resemblance to the same sex of G. beldingi 

 being quite close. It was a bird of this type that was described 

 by Mr. Cory as the female of G. rostrata, his original specimen 

 being now before me. 



Bearing in mind the nature of the variations exhibited by the 

 series from New Providence, let us now take up the birds from the 

 northernmost islands, Abaco, Little Abaco, and Great Bahama, 

 which, together with their outlying cays, are represented by a series 

 of thirty-eight specimens, of which seven are adult females, one a 

 female in juvenal dress, and one a young male in postjuvenal moult. 

 The Abaco bird was first described by Mr. Ridgway, as aforesaid, 

 under the name Geothlypis tanneri, and with the type specimens 

 all the skins but twelve agree — three from Great Bahama, two 

 from Little Abaco, and seven from Abaco. These twelve skins 

 are obviously referable to Mr. Ridgway 's G. incompta, the type of 

 which was one of the four specimens listed under the original 

 description of G. tanneri. Taking up the specimens representing 

 this latter species first, we find that they differ from G. maynardi in 

 the following particulars: (1) the general olive color of the upper 

 parts has a brownish cast, quite evident when the two series lie 

 side by side; (2) the gray of the crown is less obvious, and some- 

 times replaced by greenish olive or brownish (the same shade as in 

 G. beldingi), while the paler anterior margin is scarcely or not indi- 

 cated; (3) the superciliaries are decidedly yellow, passing into white 

 posteriorly; (4) the yellow below averages deeper, while the 

 flanks are washed with brownish yellow. The size, however, is 

 the same as in G. maynardi. I am unable to point out any constant 

 differences between the females of G. maynardi and G. tanneri; 

 the latter, however, seem to average a little more richly colored 

 below.
