Range. — Southern Mexico to southern Brazil, etc.; Lesser Antilles 

 (islands of Guadeloupe, Martinique, and Santa Lucia). 



The above diagnosis is drawn up from the Central American spe- 

 cies (exclusive of H. alhicollis Vieillot) and certain South American 

 species which are unquestionably congeneric with them. I am very 

 doubtful whether S. albicollis should be placed in this genus, the dif- 

 ference in the form of the bill and style of coloration being very con- 

 spicuous, though for the present I leave it there. Several South 

 American species which have hitherto been referred to Saltator, 

 mainly on account of, their strong resemblance in coloration, should 

 undoubtedly be removed. One of them {S. maxillosus Cabanis) has 

 already been made the type of a distinct genus,^ characterized, in 

 part, by the transvei'se, file-like corrugation of the under surface of 

 the maxilla.

 b. Upper parts (except pileum ) bright yellowish olive-green, 

 c. Larger (tail more than 107.95) ; pileum deep black, abruptly defined poste- 

 riorly. [Saltator atriceps.)

 wanting. (Isthmus of Panama to Costa Rica. ) 



Saltator atriceps lacertosns (p. 663) 



cc. Smaller (tail less than 107.95, usually less than 101.60) ; pileum olive, grayish, 



or dusky, or if approaching black the color not abruptly defined posteriorly. 



( Saltator magnoides. ) 



d. Black jugular collar broader, never interrupted nor wanting; huffy throal> 



patch narrower, deeper buff; gray of breast, etc., deeper, less brownish. 



e. Pileum dusky, sometimes nearly black; gray on sides of head darker. 



(Southern Mexico. ) Saltator magnoides magnoides (p. 663)

lighter. (Guatemala to Costa Rica. ) . Saltator magnoides mediamis ( p. 664) 



dd. Black jugular collar narrower, often interrupted, sometimes wanting; 



buffy throat-patch broader, paler; gray of breast, etc., paler, more 



brownish. (Isthmus of Panama to Veragua. )
