third), and deeply lacerated or fringed externally at the end; the edge along 
the median portion folded over on the upper surface, but not adherent. 
On page 161 I have given the reasons for considering ‘Dendroica 
tigrina” as the type of a special genus of Sylvicolidx, and for re- 
taining it in this family rather than placing it in Caerebide, to which 
there is so much apparent resemblance in the tongue. In the struc- 
ture and character of this organ the species differs very widely from 
other members of the family, as is shown in the cuts on page 163 
accompanying those remarks. 
The curvature of the bill in Perissoglossa tigrina is quite peculiar 
among the Sylvicolidz with notched bills. Some Helminthophagas 
(without notch) approximate this character; though in none, except- 
ing H. bachmani, is it in equal amount—all the others having the 
gonys very slightly convex, instead of straight or even slightly con- 
cave. It will be of much interest to examine the tongue of H. 
bachmani, should the opportunity ever offer, as it is quite likely to 
exhibit some noteworthy feature. 
The peculiarities of the tongue of P. tigrina, and its guppoce” 
relationships to Certhiola, were first brought to notice by Mr. Gosse.

It is an interesting fact in the history of this bird, that it breeds 
in Jamaica—specimens of the eggs, as well as of the bird itself, 
killed in June, July, and August, having been transmitted by Mr. 
March. These appear to have longer wings, a larger white spot on 
the tail feathers, and more orange-brown on the throat than I re- 
member to have seen in North American birds ; but better specimens 
will be required to substantiate any real difference.
