deep black. All the rest have the under mandible pale brownish, the 

 upper, deep brown or dusky. Among the latter are apparently adult 

 birds of both sexes, obtained April 5, and June 10-18; but they may 

 be young birds which have just assumed the adult plumage. 



GEU.SPIZA ASSIMILIS (Gould?). 



Indefatigable Island (7 specimens); Albemarle (1 ?);* Cowly Bay, East 

 Albemarle (1!);* Jervis (5). 



Without a specimen of true G. a.ssimilis, from Bindloe Island, for 

 comparison, I am not sure as to the correctness of this identificatiou. 

 Whether G. assimilis or not, however, it certainly can not be referred 

 either to G. scandens or G. ahingdoni, being much larger-billed than tbe 

 former and smaller-billed than the latter; in fiict, it is about iuteruie- 

 diate between the two, without, however, grading into either, so far as 

 is indicated by a series of thirty-two specimens.! 



It may be remarked that the color of the bill is the same in the three 

 forms, when specimens of corresponding sex, age, and season are com- 

 pared. Thus, although the adult male of C. saoidcns is described as 

 having the bill varied with yellow, all of the six adult males in Dr. 

 Baur's collection from James Island (the type locality) have the bill 

 wholly black, as do also two males in striped plumage and an adult 

 female. The plumage aj^pears to be quite the same in the three forms. 



Should this form ])rovfj to be different from G. assimilis, I propose for 

 it the name G. intermedia (type ^o. 115916, CJ. S. N. M., Charles Island, 

 April 8; C. H. Townsend). 



9. GEOiSPIZA BARRINGTOXI, new species. 



Specific characters. — Similar to G. ahingdoni, Salvin, but bill much 

 stouter, with tip less compressed and less acute. Wing, 2.70-2.80; tail, 

 1.58-1.62; culmen, 0.79-0.80; tarsus, 0.90; middle toe, 0.70. 



Habitat. — Barrington Island. (Type, No. 596, in Dr. Baur's collec- 

 tion, obtained July 9, 1891.) 



Dr. Baur's collection contains three specimeusof this form, two adult 

 males and a specimen in the streaked plumage. 



10. GEOSPIZA PROPINQUA, new species. 



Specific characters. — Very similar to G. conirostris, Ridgway,^ of Hood 

 Island, but bill still narrower, with the under mandible no broader 

 than the upper; wing slightly shorter. 



Measurements of type (aSO. 597, coll. Dr. G. Baur, Sept. 2, 1891). — Wiug, 



* The specimens from Albemarle and Cowly Bay, East Albemarle, being young 

 birds, are very doubtfully placed here. 



IThe National Museum collection contains the following specimens of this form: 

 Charles Island (10 specimens); Indefatigable (6); Chatham (If) — the last doubt- 

 fully referred here.
