Range. — Soutluu'ii Mexico to southern lii'azil, ete. ; Lesser Antilles 

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



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

 cies (exclusive of S. aJJ)icollis Vieillot) and certain South American 

 species which arc unquestionabl}^ congeneric with them. I am very 

 doubtful whether .S'. alhicollis 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 SaUat(>r\ 

 mainly on account of their strong resemblance in coloration, should 

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

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

 part, by the transverse, file-like corrugation of the under surface of 

 the maxilla.
