BIRDS—FRINGILLIDAE—CURVIROSTRA LEUCOPTERA. A27 
have at hand, (wing 3.65 inches.) No. 8962 has a still larger bill. In fact, there appears to be 
a great difference in the size of the bill in different specimens, and this indiscriminately in 
both eastern and western skins. 
The difference between the European and American Crossbills appears to consist chiefly in the 
larger size, with larger and stouter bill of the former. 
A Loxia mexicana, described by Strickland, is said by Bonaparte to have the same relation- 
ship to the americana that pytiopsittacus has to curvirostra, namely, a larger bill. I cannot 
; now lay my hand on Mr. Strickland’s article, but I doubt whether the characters furnished by 
a a comparison of a small number of specimens will lead to very satisfactory results, in view of 
the great differences observable in size of bill in specimens from the same locality.
