II, ii)OJ, 5i()). U is only necessary to assume that the prenuptial 

 ni.uilt is more or less incomplete, not involving the tail or wings (cxcei)t 

 the tertiaries and perhaps a few of the secondaries), and sometimes 

 not all of the wing-coverts and body-plumage, to account for the 

 peculiarities in question. As is often the case, the moult is less ex- 

 tensive in the female birds, but I have examined at least one immature 

 male (No, 21759, Cory Collection, Abaco, March 17, 1891, erroneously 

 sexed as a female) whose appearance would suggest that such a sup- 

 pression is not confined to that sex. 



The wing-formula in this species is more or less obscured in the case 

 of worn specimens, which are difificult to distinguish from Dendroica 

 ccstiva. Unfortunately I have not been able to make any extended 

 comparisons of the present form with the Cuban bird, and the char- 

 acters assigned for its separation do not appear to me very trenchant. 



62. Dendroica caenilescens caerulescens (Gmelin). 

 One specimen: New Providence (Blue Hills). 



A male in the plumage of the first winter, with no sign of moult. 

 The amount of black on the back would indicate that it was a bird 

 from the southern Alleghanies, assuming that cairn si is a valid form, 

 which in my opinion is exceedingly doubtful. 



63. Dendroica coronata (Linnaeus). 



One specimen: Watlings Island, March 13, a female in worn first 

 winter dress. 



64. Dendroica dominica dominica (Linnaeus). 

 Two specimens: New Providence (Blue Hills). 



These two examples (both females) measure as follows: wing, 

 59 and 62 mm.; tail, 44 and 47.5; exposed culmen, 12 and 13. Eight 

 females from the United States average: wing, 64; tail, 48; exposed 

 culmen, 14. Besides being slightly smaller, they are paler, and have 

 less black on the forehead than any individuals in a large series before 

 me from Florida, South Carolina, and Georgia. Thinking that they 

 might represent an undescribed'Iocal form, I secured the loan of the 

 Bahaman and West Indian series of this species in the Field Museum 

 for comparison. But after a very careful study of this material I 

 am unable to verify this supposition. It is true that there are a few 

 individuals whose measurements are slightly below the average and 

 whose colors are more or less pale, but in most cases such are obviously 

 immature birds, and I am not disposed to give these characters any
