Range. — Abingdon and Bindloe. 



Similar to G.f. parvula, but averaging smaller, wing usually less 

 than sixty millimeters, culmen about twelve and one half. 



This variety is common on both Abingdon and Bindloe. It occurs 

 everywhere on Bindloe which is comparatively low, but on Abingdon 

 it was found only below eight hundred feet altitude, Abingdon 

 reaching an elevation of nineteen hundred feet.

62J. GEOSPIZA FULIGINOSA ACUTIROSTRIS 

 (Ridgway). 1 



Geospiza acutirostris Ridgway, Proc. U. S. Nat. Mus., xvii, p. 363, 1894, 

 and xix, p. 531, 1896 ; Bull. U. S. Nat. Mus., 50, Pt. i, p. 506, 1901. — 

 Rothschild and Hartert, Novit. Zool., vi, p. 162, 1899. 



Range. — Tower Island. 



Very similar to G. f. fuliginosa., but bill more acute, with straighter 

 outlines ; the culmen averaging fourteen and one half millimeters and 

 the basal depth eight and one half millimeters. Our birds, which 

 were taken in June, all have pinkish-horn-colored bills, but are appa- 

 rently adult. 



This is the most common Geospiza on Tower, where it occurs 

 abundantly near the coast, frequenting the cactus {Opuntia) 

 thickets.
