under the name of C. merriami, and comparing it with 

 C. montezumce !! [vide infra]. 



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 dai'ker, the mantle and under parts are dark 

 chestnut instead of pale chestnut, and the black on the chin 

 and throat extends somewhat fui'ther 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 O. atriceps Grant, from W. Mexico, 

 but the male has the upper parts much darker and almost 

 devoid of rufous markings, the chestnut wliich 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, hoivever, 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 montezumce 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 ditt'erences 

 mentioned in the description, so far as we can sec, have no 

 real existence.
