HARPORHYNCHUS.

the feathers of crissum rufous, edged with pale brownish-yellow 

 (instead of their being dirty white). The bill is very different, 

 being longer, slenderer, more pointed towards the end, and more 

 gently decurved than that of H. curvirostris. Its dimensions are 

 as follows: From forehead, 1.40; from gape, 1.52; from nostril, 

 1.00, measured with dividers. In 4,016, from Brownsville, the 

 measurements are: From forehead, 1.25; from gape, 1.32; from 

 nostril, .83. 



Without more specimens to establish a permanent difference in 

 these respects, I do not feel at liberty to suggest a difference of 

 species, especially as the skin referred to belongs to the region in- 

 habited by typical H. longirosti'is.

Hab. Mexico, from the United States line, southward (Oaxaca, Cordova, 

 Orizaba, Mirador) ; Mazatlan ; Colima. 



Specimens from Mazatlan and Colima differ from those in the col- 

 lection from ea.stern Mexico, in having heavier and thicker bills, and 

 perhaps stouter legs. In 31,819, the height of the bill at the nostrils 

 is .28 of an inch, while in 4,023 it is .26 — both being females. The 

 wing in 31,819 is longer and more pointed than usual, measuring 

 4.50. I, however, cannot think that there is any specific difference : 

 a large number of specimens from either side of Mexico probably 

 exhibiting the same variations.
