third), and deeply lacerated or fringed externally at the end; the edge along 

 the median portion folded over on the upj^er surface, but not adherent. 



Ou page 161 I have given the reasons for considering "Dendroica 

 tigrina" as the type of a special genus of Sylvicolidae, and for re- 

 taining it in this family rather than placing it in Cserebidse, 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 ou page 1G3 

 accompanying those remarks. 



The curvature of the bill in Perissoglossa tigrina is quite peculiar 

 among the SijlvicoUdse 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. tiginna, and its supposed 

 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.
