and the breast rather indistinctly marked with dusky. Length (skin), 

 4.70; wing, 2.78; tail, 1.70; culmen, 0.70; gonys, 0.38; width of under 

 mandible at base, 0.40 : depth of bill at base, 0.52 ; tarsus, 0.90 ; middle 



toe, 0.02. 



13. GEOSPIZA P'RATERCULA, new species. 



Specific characters. — Similar to G.fortis, Gould, of Charles Island, but 

 smaller, the bill narrower and with culmen more convex. Adult males : 

 Wing, 2.50-2.65; tail, l.GO-1.65; culmen, 0.G5-0.67; depth of bill at 

 base, 0.43-0.49; tarsus, 0.78-0.80. 



Habitat— Abingdon Island, Galapagos. (Type, No. IKUIO, U.S.X.M., 

 Abingdon Island, Ai)ril 10; C. H. Townsend. 



Five adult males in the National Museum coUecticm from Abingdon 

 Island agree in the above character, by which they may readily be dis- 

 tinguished from G. fortis, of Charles Island. There are four young 

 birds in the collection, but no adult females. Mr. Salvin says that 

 "the females from Abingdon Island are darker than those from the 

 other two islands"' (Indefatigable and Biudloe). 



14. GEOSPIZA DEBILIROSTRIS, new species. 



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

 and stouter, and bill conspicuously smaller. Wing, 2,93; tail, 1.75; 

 culmen, O.GO; depth ot bill at base, 0.35; tarsus, 0,95; middle toe, 0.67. 



Habitat.— James Island, Galapagos. (Type, No. 116003, U.S.N.M., 

 <? ad., James Island, April 11 ; C. 11. Townsend,) 



Of this very distinct species I have seen but one specimen. The 

 plumage is "solid'' black, varied by a slight admixture of bufiy whitish 

 on the middle of the abdomen, and broad terminal margins of the same 

 to the longer under tail-coverts, becoming tinged with bright rusty ante- 

 riorly. The bill is wholly deep black, the legs and feet broAvnish black. 



The bill is shaped exactly as in G. fuUginosa. but is slightly larger. 



15. GEOSPIZA ACUTIROSTRIS, iiew species. 



Specific characters. — Similar to G.p<(rvula, Gould, but bill longer, with 

 straighter outlines, and extremely acute at tip. 



Measurements of type. — Wing, 2.45; tail, 1.58; culmen, 0.55; depth of 

 bill at base, 0.30; tarsus, 0.75; middle toe, 0,53, 



Habitat. — Tower Island, Galapagos. (Type in Dr. Baur's collection.) 



The form of the bill in this species is conspicuously unlike that of 

 any other, being almost exactly that of Carduelis. 



There are 7 specimens in Dr, Baur's collection, 4 of which are in the 

 black plumage. 



16. CAMARHYNCHUS ROSTRATUS, new species. 



Specific characters. — Similar to C. habeli, Sclater and Salvin, of 

 Abingdon Island, but larger, with the bill much deeper and broader 

 with much more strongly arched culmen.
