fosssB much larger, and maxillary tominm more distinctly lobed or con- 

 vox in middle portion. Female much darker thau in any allied forms. 



Range. — Galapagos Archipelago : "r?Charles Island (Markham); Ab-

Aihdt male.—No. 116117, U.S.N.M.; Abingdon Island, (.ralapagos, 

 April 1(3, 18S8; C. H. Townsend. Entirely unitbrin deep black, the

 tail, 1.50; cnlmen, 0.58; gonys, 0.31; basal width of mandible, 0.28; 

 basal depth of bill, 0.37; tarsus, 0.80, middle toe, 0.53. 



Adult (?) female.— No. 11G118, U.S.K.M.; same locality, etc. Above 

 dull grayish dusky (inclining to grayish or olivaceous black on head 

 and neck), the feathers margined with olivaceous; beneath dusky slate, 

 nearly uniform anteriorly, but feathers everywhere margined with light 

 buffy olive, most broadly on under parts of the body, especially pos- 

 teriorly, where nearly uniform on belly and Hanks ; under tail-coverts 

 light brownish buffy, tinged with olive, each with a central longitu- 

 dinal spot of dusky. Bill, legs, and feet brownish black. Length 

 (skin), 4.75; wing, 2.35; tail, 1,45; culmen (tip of maxilla broken); 

 gonys, 0.29; basal width of mandible, 0.24; tarsus, 0.80; middle toe,

I doubt the correctness of the identification, or the locality, of the 

 Charles Island specimen collected by Captain Markham.

kSpecific characters. — Similar to G. fortis, Gould, in size, but feet larger 

 and stouter, and bill conspicuously smaller,

Adult »ta7e.— Type, No. 110003, U.S.X.M.; James Island, Galapagos, 

 April 11, 1888; C. H. Townsend. Entirely uniform deep black (less 

 intense posteriorly), the feathers abruptly clear slate-gray beneath the 

 surface; lower part of abdomen intermixed with bufly whitish, and 

 longer under tail-coverts broadly margined terminally with the same, 

 tinged with light rusty; bill wholly deep black; legs and feet brownish 

 black. Length (skin), 4.90; wing, 2.93; tail, 1.70; culmen, 0,00; 

 gonys, 0.30; basal width of mandible, 0.30; basal depth of bill, 0.37; 

 tarsus, 0.95 ; middle toe, 0.G7. 



Of this apparently very distinct species I have seen but one speci- 

 men. Although the general dimensions are nearer those of G. fortis 

 thau any other form of the genus, the bill is scarcely larger than in 

 G.fidiyitL06ay and has exactly the same form as in that species.
