pallcsccns, as staled li\- Mr. Rik-y (in Shaltuck, Tlic liahatua Islands, 

 1905, 352) — while the l)ill is wliollydark (in the dry skin; unfortunately 

 the colors when fresh are not stated). 



27. Chaemepelia passerina exigua (Riley). 



Ten specimens: ("irt'at Inagua (Alfrefl Sound, Malhewtown). 



This series difi'ers from the New Providence birds in smaller size 

 and decidedly paler coloration, a\eraging paler even than C. p. 

 pallcsccns. Upon comparison they prove to be referable to the form 

 from Moiia Island, Porto Rico, described by Mr. Rile\- as Cnlum- 

 bi^allina passerina exigua {Proceedings United States National Museum, 

 XXIX, 1905, 171). The discovery that two readily separable but 

 intergrading forms of the ("iround I)o\-e inhabit the Bahama Islands 

 is in line with other facts of distribution already- known, and will be 

 discussed more fully in another connection. 



There is a young bird in juxeiial dress from Mathewtown, February 

 26, indicating that the species breeds \ery early. 



2S. Falco columbarius columbarius Linnanis. 

 One specimen: New Pro\idence (Blue Hills). 



29. Amazona leucocephala bahamensis (Bryant). 



Six specimens: Acklin Island (Pompey Bay). 



"Iris grayish yellow; bill white; feet yellow." 



The present series, secured by Mr. Worthington after strenuous 

 efforts, taken in connection with the specimens in the American and 

 the Field Museums, has afforded a fair basis for determining the 

 status of this form, whose standing as a subspecies has been considered 

 doubtful. First, as regards relative size, the following table of meas- 

 urements gives the necessary data:
