PRELIMIi^ARY DESCRIPTION OF SOME NEW BIRDS FROM 

 THE GALAPAGOS ARCHIPELAGO. 



By Robert Ridgway, 



Curator of the Department of Ilirds. 



During the fiual elaboration of iny mouograpli of the birds of the 

 Galapagos Archipelago,' the necessity of again examining some of Dr. 

 Baur's specimens became evident. These were kindly lent me by Dr. 

 Baur, and have been most carefully compared. As a result I find 

 myself comi^elled to describe the following as new, it being impossible 

 to identify them with any of the forms already named. 



GEOSPIZA PACHYRHYNCHA, new species. 



Specific characters. — Similar to G. strenua, Gould, but bill much thicker 

 and broader at the base than m that form, in this respect nearly or quite 

 equaling G. magnirostris, Gould. Exposed culmen, plus 0.90 inch;^ 

 depth of bill at base, 0,88; width of mandible at base (across chin), 0.70; 

 gonys, 0.40. 



Range. — Galapagos Archipelago (Tower Island, collected by Baur and 

 Adams. Type in Dr. Baur's collection). 



GEOSPIZA FATIGATA, new species. 



Specific characters. — Similar to G. intermedia, Ridgway, of Charles 

 Island, but slightly larger, with the bill, legs, and toes decidedly longer. 

 Wing, 2.05-2.82 inches; tail, 1.05-1.73; culmen, 0.82-0.89; depth of bill 

 at base, 0.40; width of mandible at base (across chin), 0.35-0.39; tarsus, 

 0.85-0.90. 



Range. — Galapagos Archipelago (Indefatigable Island, collected by 

 Habel, Townsend, Baur and Adams ; 1 ! Chatham Island, collected by 

 Townsend). 



Type.—^o. 110048, U. S. N. M., male adult, Indefatigable Island, 

 April 12, 1888; collected by C. H. Townsend.

2The measuremeuts here given are taken from a drawing, the specimens having 

 been returned to Dr. Baur.
