HARPORHYNCHUS. 45 
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 HZ. longirostris.

Specimens from Mazatlan and Colima differ from those in the col- 
lection from eastern Mexico, in haying 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.
