Geothlypis incompta, however, may be readily distinguished from 

 G. tanncri, differing (1) in its slightly smaller size; (2) in its duller 

 coloration above, the erown and back being less strongly contrasted; 

 (3) in its much paler superciliaries, which are whitish or yellowish 

 white; (4) in the yellow below being decidedly duller, especially 

 on the abdomen; (5) in the color of the flanks, which are light 

 buffy grayish brown, exactly as in G. rostrata. 



We are now prepared to consider our series from Andros Island, 

 consisting of nine specimens, all but one males. Although so few 

 in number, two distinct types arc represented, corresponding to 

 those inhabiting both New Providence and the northern islands. 

 Although the type specimen of G. exigua is unfortunately not avail- 

 able, the description indicates a dull-colored bird of the rostrata- 

 incompta group, but with a shorter wing and smaller and more 

 slender bill. In view of the range of variation exhibited in the 

 measurements of the other forms, I am not inclined to attach 

 any great significance to these differences, even though a larger 

 series prove their constancy, as they are at most very slight 

 and in my judgment unworthy of nomenclatural recognition. 

 In fact, after a very careful comparison I find myself quite 

 unable to distinguish three of the Andros birds (Nos. 39531- 

 39533, Field Museum Collection) from G. rostrata, and should 

 refer them to that form without hesitation. The other five male 

 examples, which are all of the bright-colored type, are not so easily 

 allocated, but on the whole seem best referred to G. maynardi, 

 although the superciliaries have rather more yellow than the aver- 

 age of that form. The single female bird is also best placed here. 



One other form, Geothlypis coryi, from Eleuthera Island, remains 

 to be considered. Besides the type, nine specimens are available, 

 including two females. This form seems sufficiently distinct at 

 first glance to stand as a full species. It is characterized by its 

 bright coloration, the olive green of the upper parts being much 

 brighter than in any of the other forms, and the crown shows 

 scarcely a trace of gray, being almost as green as the back — even 

 more so in worn plumage — while the superciliaries are almost 

 wholly bright yellow, with only a trace of white along the upper 

 margin of the black auricular patch. The post-frontal band also 

 is yellowish, but is not very distinctly indicated. Below, the yellow 

 is as rich as in G. maynardi, and the flanks similarly colored. In
