 Walk^), northeastern Honduras (Yaruca),'^ Costa Rica (Angostura; 

 Cervantes; Valza; Turrialba; Guapiles; Carrillo; Cariblanco de Sara- 

 pique; Jimenez; Pozo Azul de Pirris; Volcan de Miravalles'*), and

« Eleven specimens. 

 b Ten specimens. 



c Three adult females from Manatee Lagoon, British Honduras, and one from Yaruca, 

 Honduras, are decidedly referable to this southern form, if a subdivision of the species 

 is to be made. I have had the advantage of a much larger series of the southern form 

 than that examined by Mr. Bangs, and find that by restricting true S. verse-pads to 

 birds from southern Mexico, Guatemala, and western and central Honduras specimens 

 from all other localities stand out clearly by the characters given in the above diag- 

 nosis, and none of them more strongly than the liirds from Manatee Lagoon! I am 

 unable to account for this distribution unless on the hypothesis that S. v. durnicola 

 follows the coast or coast-slope of Honduras only and thus reaches the coast of British 

 Honduras. Birds from Chamelicon and San Pedro, which are near the coast in north- 

 western Honduras, are partly undistinguishable from Guatemalan examples, and 

 therefore are true S. versc-pacis and partly intermediate, though rather nearer to the 

 northern form. Unless a subdivision of the species is made as indicated, I do not see 

 how S. r. durnicola can l)e maintained as a vaild form, since otherwise there are neither 

 color-characters nor differences of proportions on which fo base it. 



<^ I have not seen specimens from these localities and therefore can not be sure that I 

 have allocated the records correctly.
