 Dr. Baur's collection. 



This form approaches G. strenua in the size and form of the beak, 

 but the gap between them is very considerable. The bill is also pro- 

 portionally much more compressed than in G. strenua. 



12. GEOSPIZA ALBEMARLEI, uew species. 



Specific characters. — Intermediate between G. media, of Hood Island, 

 and G. duhia, Gould, of Chatham.

Measurements of type. — (No. 115977, U.S.N.M., immature S , Tagus

 wing, 2.80; tail, 1.85; culmen, 0.70; gonys, 0.35; width of lower man- 

 dible at base, 0.41 ; depth of bill at base, 0.52 ; tarsus, 0.85; middle toe,

The plumage of the type specimen is about half-way between that of 

 the young male and the jjerfectly adult bird, the head and neck being 

 nearly uniform dull blackish, the feathers of the dorsal region black, 

 broadly margined with olive, the under parts (except throat) dull buffy 

 whitish (marked with buffy olive laterally); the entire breast and fore 

 part of sides heavily spotted (longitudinally) with blackish. 



An adult female (No. 115978, U.S.N.M., same locality, etc.), is 

 exactly like the immature male in coloration; its measurement being 

 as follows: Length (skin), 5; wing, 2.82; tail, 1.70; culmen, 0.75; 

 gonys, 0.40; width of under mandible at base, 0.42; depth of bill at 

 base, 0.55; tarsus, 0.90; middle toe, 0.65. 



Another female (No. 115975, U.S.N.M,, same locality, etc.), evi- 

 dently not a very young bird, since its bill, like that of the two above-men- 

 tioned specimens, is very hard and chiefly black in color, has the toj) of 

 the head grayish olive, broadly streaked with dusky, the cheeks, chin, 

 throat, etc., very pale grayish buffy, obsoletely streaked Avith darker.
