Oeospiza fuliginosa minor Rothschild and Hartert, Novit. Zool., vi, Aug., 1899, 

 162 (Bindloe and Abingdon islands, Galapagos; Tring Mus.). 



GEOSPIZA ACUTIROSTRIS Ridgway. 

 SHAKF-BILLED GROUND FINCH. 



Similar to G. fuliginosa but bill longer, with straighter outlines 

 and extremely acute at tip. 



Adult viale.—Wing, 62.23; tail, 40.13; culmen, 13.97; depth of bill 

 at base, 7.62; tarsus, 19.05; middle toe, 13.46. 



Galapagos Archipelago (Tower Island). 



1 Dr. Sharpe designates as the types of G. parvula a pair from Chatham Island, but 

 as Mr. Darwin mentions only James Island in connection with his supposed species 

 this is no doubt an error. 



^Four specimens (three adults, one immature) from Abingdon Island. Messrs. 

 Rothschild and Hartert do not, unfortunately, separate the sexes in their measure- 

 ments. They give the extremes in a series of 116 specimens (43 from Bindloe 

 Island, 73 from Abingdon Island), which are as follows: 



Specimens from Bindloe Island. — Wing, 58.00-62.00; culmen, 11.00-13.50. 



Specimens from Abingdon Island. — Wing, 58.00-63.00; culmen, 12.00-13.50.
