DENDROICA VIGORSII ACHRUSTERA (Bangs). 

 NASSAU PINE WARBLER. 



Similar to D. v. vkjors!!^ but wiiij^- much shorter, tail relatively longer, 

 and bill and feet larger; 3^ellow of under parts averaging paler, not 

 extending to flanks or lower abdomen; yellow supraloral line averag- 

 ing broader, more distinct; white on inner webs of lateral rectrices 

 more restricted. Young (in first plumage) with upper parts much 

 browner (cinnamon-brown or nearly prouts brown). 



Adult male.— Length (skins), 117-130 (123.2); wing. 61-69 (65.9); 

 tail, 54-56 (54.2); exposed culmen, 11.5-12.5 (12); depth of bill at 

 nostrils, 4-4.5 (4.1); tarsus, 18.5-19 (18.9); middle toe, 13-13.5 (13.4).^ 



Adult female.— \.cngih (skins), 120-123 (121.5); wing, 62-63 (62.5); 

 tail, 51.5-52 (51.7); exposed culmen, 12-12.5 (12.2); depth of bill at 

 nostrils, 4; tarsus, 19-19.5 (19.2); middle toe, 13-13.5 (13.2).' 



Island of New Providence, Bahamas. 



This is clearly an insular form of D. vigorsu., differing only in its 

 shorter wing, larger bill and feet, and relatively longer tail. Ever}^ 

 character of coloration in adult birds I find in occasional specimens of 

 true D. vigordi., which is exceedingly variable in respect to extent of 

 the yellow on the under parts, and other color characters.

' Four specimens. 



^ Two specimens. 



^ No particular island is mentioned, but a specimen from the Bryant collection in 

 the U. S. National Museum collection agrees closely with the examples from New 

 Providence, and is probably from that island.
