Specific characters. — (No specimens seen by me, and the various pub- 

 lished descriptions, purporting to have been taken from the same speci- 

 men, are conspicuously at variance in regard to the principal characters 

 of plumage, besides showing important discrepancies as to measure- 

 ments.) 

 Range. — Gahipagos Archipelago: Charles Island? (Darwin.) 

 Three descriptions of this species, all purporting to have been taken 

 from the same specimen (the type, now in the British Museum), are as 

 follows : 



I. 



" C. (Mas. jun. et Foem.) corpore superiore intense brunneo, singulis 

 plumis cinerascenti-olivaceo marginatis; gutture pectoreque cineras- 

 centi-olivaceis, singulis in medio plumis obscurioribus; abdomine late- 

 ribus crissoque cinereis stramineo tinctis. 



"Long, tot., oi unc. ; ahe, 3.34; caudic, 13; tarsi, 1^; rostri. A; alt. 

 rostri, i. 



"Upper part of the body (]eep brown, with each feather margined 

 with cinereous olive; the throat and breast cinereous olive, with tlie 

 middle of each feather darker; the abdomen, sides, and under tail- 

 coverts cinereous tinged with straw-color. 



'•^Habitat. — Galapagos Archipelago (Charles Island?)." (Gould.) 



II. 



"Supra cinereus; capite fuliginoso-nigro: subtus albidus, gula et 

 pectore superiore plumis singulis medialiter nigris: tectricibus alarum 

 et rectricum apicibus fusco albido marginatis: long, tota 5.2, ahie 3, 

 Cauda- 1.9, tarsi 0.85, rostri a rictu 0.5. 



"Jlrtfei/rtt— Charles Island {"I) [Darwin). 



"The type specimen in the British Museum, from which the above 

 description is taken, is probably an adult male." (Salvin.) 



III. 



"The type specimen is probably a young male. It differs from G. 

 variegatus in its uniform under surface not beiug mottled with brown 

 streaks. It has a slight indentation in the cutting edge of the upper 

 mandible answering to G. dentiros^ris in the genus Geosinza. Total 

 length, 5.3 inches; culmen, 0.6; wing, 3.05; tail, 1.9; tarsus, 0.9."
