5 a. Colinus insignis Nelson_, Auk, xiv. p. 46 (1897) 
[Valley of Comitan, Chiapas, and Nenton, Guatemala). 
The British Museum possesses a series of this species col- 
lected by W. B. Richardson at Comitan and in the Chiapas 
Plains in May 1897. The females agree perfectly with the 
description of the type female given by Mr. Nelson : the 
males, which have never been described, very closely re- 
semble the males of C. ridgwayi Brewst. ; but the plumage is 
throughout darker, the mantle and under parts are dark 
chestnut instead of pale chestnut, and the black on the chin 
and throat ^extends somewhat further down the fore-neck. 
7 a. Colinus salvini Nelson, Auk, xiv. p. 45 (1897) 
[Tapachula and San Benito, Chiapas, Mexico] . 
We have a series of this species from San Benito. It 
is most nearly allied to 0. atriceps Grant, from W. Mexico, 
but the male has the upper parts much darker and almost 
devoid of rufous markings, the chestnut which forms an 
ill-defined collar in O. atriceps on the nape and upper 
mantle being replaced by black, while in most specimens 
the dull chestnut feathers of the breast and belly are mar- 
gined with black ; it should be noted, however, that in some 
males the black margins are indistinct or even absent. These 
are perhaps immature birds. The female is much darker 
than the female of O. atriceps, and has the ground-colour of 
the under parts white instead of buff. 
1. Cyrtonyx MONTEZUMA (op. cit. p. 425). 
Cyrtonyx montezuince mearnsi Nelson, Auk, xvii. p. 255 
(1900) [South-western Texas and the southern half of New 
Mexico and Arizona, ranging into N. Mexico] . 
We have examined a number of examples of this supposed 
subspecies, but neither Mr. Godman nor I have been able 
to see the slightest ground for separating it ; the differences 
mentioned in the description, so far as we can see, have no 
real existence.
