Specific characters. — (Adult male unknown.) Adult female similar to 

 that of C. psittaculus, Gould, but smaller, with the bill much narrower, 

 mure compressed, and with straighterculmeu; basal width of mandible

 less than length of maxilla frcmi nostril. Wing less than li.OO; cuhnen 

 (from extreme base), O.OO; basal depth of bill, 0.40. 



Ramje. — Galapagos Archipelago: Jervis Island (Baur and Adams). 



Adult female. — Type, No. 471, collection of Dr. G. Baur; Jervis Island, 

 Galapagos, August 8, 1891. Above light olive (less grayish than in 

 Cpsittaculufi, more so than in G. incerfus) thepileum obsoletely streaked 

 and the back spotted with darker; wings and tail dusky grayish brown, 

 the feathers with light buflfy olive margins, the middle and greater 

 wing-coverts broadly tipped (the former sharply) with pale brownish 

 buff; face and under parts very pale yellowish buff, tinged with pale 

 olive-brown on sides and flanks, where obsoletely streaked (broadly) 

 with grayish olive-brown; under wing-coverts white tinged with pale 

 buff", most strongly toward edge of wing. Maxilla pale cinnamon-brown, 

 with terminal portion of culmen dusky; mandible paler, inclining to 

 brownish buff"; "iris very dark brown;" legs and feet blackish brown. 

 Length (skhi), 4.25; wing, -!.57; tail'; culmen, 0.00; gonys, 0.32; width 

 of mandible at base, 0.29; depth of bill at base, 0.40; tarsus, 0.90; mid- 

 dle toe, 0.00. 



While very closely resembling the female of C. psittaculus in general 

 ap])earance, the decidedly shorter wing and very diff'erent proportions 

 of the bill will serve to readily distinguish it from that form. 



' Rectrices only partly grown out.
