In the Tres Marias Islands, Grayson found this Pyranga to be abundant, and a 

 resident species, but as he did not meet with it on the opposite mainland he thought it 

 a bird peculiar to these islands ''. We have lately received specimens from the Tres 

 Marias obtained in August 1881 by Mr. A. Forrer. These are hardly so bright- 

 coloured as our Mexican and Central-American specimens, but this may be due to the 

 time of year at which they were shot. There is a great diiference, however, in the 

 size of the bill, that of the island birds being much more robust in every way and 

 the characteristic tooth unusually developed. Failing other differences, and having 

 only a pair of the island birds, we are hardly disposed to separate them on this account. 

 In Mexico P. bidentata is found in the higher and temperate districts ; but it does 

 not seem to occur much beyond Temiscaltepec, where Bullock first discovered it. 

 Its name is absent from Dr. Duges's list of Guanajuato birds. 



In Guatemala we found it abundant in the forests of the Volcan de Fuego from 

 about 4000 feet above the sea at Barranco Hondo to the ridge above Calderas, which 

 is over 8000 feet high. It also occurred near San Geronimo in Vera Paz, but we 

 never met with specimens in the collections made by the bird-hunters of Coban. As 

 might be expected, it is absent from the lower districts of Honduras and Nicaragua, 

 but appears again in the mountains of Costa Eica and in the Volcan de Chiriqui, 

 the extreme limit of its range. Between Costa-Eican and Guatemalan specimens 

 we can trace no difference. 



The habits of this species offer no peculiarities. Its nest and eggs remain as yet 

 unknown.
