other significance. On the other hand, there are a number of speci- 

 mens, all taken from November to January inclusive, which are 

 slightly larger than the average, as well as more richly colored, the 

 yellow of the throat sometimes taking on an orange hue, approaching 

 that of the Blackburnian Warbler. These are unquestionably adult 

 birds in fresh feather. Wear and fading affect the plumage in this 

 species very markedly. 



Mr. Riley writes me that he based his listing of this species as a 

 resident in the Bahamas on the smaller size of the "resident" birds. 

 But, so far as I know, there is no record of its occurrence there in the 

 summer before July, and it is known to move southward from the 

 United States as early as this {cf. Cooke, Bulletin Biological Survey, 

 No. i8, 1904, 84). Until specimens actually taken while breeding 

 are forthcoming it would seem very unsafe to set it down otherwise 

 than as a winter visitor to the islands. 



65. Dendroica flavescens Todd. 



Four specimens: Abaco (Sand Bank, Spencer's Point). 



One individual has been renewing some of the rectrices, perhaps 

 lost by accident. 



There is little to add to the original account of this species {Pro- 

 ceedings Biological Society of Washington, XXII, 1909, 171). The 

 type is now No. 31 144 of the Carnegie Museum collection. It is 

 certainly odd that such a distinct and peculiar form should have de- 

 veloped on Abaco alone of all the group, and it would be interesting 

 to know how the conditions obtaining in its local habitat differ from 

 those in some of the other islands, Andros for example. Indeed, I 

 anticipate its discovery on Great Bahama, if not also on Andros. 

 Its characters would suggest that it had been derived from individuals 

 of Dendroica dominica dominica which may have remained behind to 

 breed. 



66. Dendroica pityophila Gundlach. 

 Thirteen specimens: Abaco (Sand Bank). 



This species is apparently so rare in collections that Mr. Ridgway 

 did not have a single Bahaman specimen before him for description 

 when writing his Birds of North and Middle America. Cuban ex- 

 amples are also few in number, but those which I have examined and 

 compared with the present tine series fail to show any differences which 

 cannot be accounted for by the effects of wear. Moreover, after a 

 critical comparison of the type series (seven skins) of Mr. Cory's
