Geospiza sca?idens, Roth, and Hart. Novit. Zool., VI, 1899, p. 165 (part). 
Type. — Irninatnre female, No. 5122, Leland Stanford Junior University Mmseuin; Biudloe Island, 
Galapagos Archipelago, June 21, 1899. 
Ra?ige. — Bindloe Island, Galapagos Archipelago. 
S?ibspecijic characters.— Mwch. IWe: G. abingdoni but the bill considerably thicker, the basal 
depth equal to or greater than length of gonys. 
Only immature specimens are in the collection but these differ so much from 
specimens of G. abingdoni of the same age that it is very probable that adults will be 
found to differ correspondingly. Some of the thickest billed specimens are nearly 
indistinguishable from small billed specimens of G. conirostris propinqua of Tower 
Island. Some are close to G. brevirostris.
