This Long-tailed Partridge is an inhabitant of the highlands of Mexico. It has 
been found in several districts by Messrs. Nelson and Goldman, and the former has 
recognized four separate races of D. macrurus. The typical form Mr. Nelson considers 
to be the bird found in the high pine- and fir-clad mountains about the Valley of 
Mexico, those inhabiting the other regions of Southern Mexico he believes to belong 
to different races. D. oaxace, from Totontepec, frequents the “ mountains of Eastern 
Oaxaca, from the Cerro San Felipe to Mount Zempoaltepec.” The white eyebrow and 
white cheek-stripe are less distinct than in D. macrurus. There are no white edges to 
the feathers on the back of the neck, and the neck and sides of the breast are almost 
uniform, the ashy edges to the feathers being very narrow. WD. oaxace is also said by 
Mr. Nelson to be a much darker bird than D. macrurus, “‘and is characterized by a 
suppression of the lighter markings seen in that species” ®. 
D. macrourus griseipectus, from Huitzilac, Morelos, inhabits the ‘ heavy oak-forest 
on the Pacific slope of the Cordillera, in the States of Morelos and Mexico.” The 
rufous stripes on the breast are nearly obsolete, so that the general colour of this 
portion of the body is “nearly uniform dingy grey; the back, rump, wings, and flanks 
are darker and more olive than in J. macrurus,” and the flanks are said to have very 
indistinct narrow lines of rufous 1°. 
D. macrourus striatus, from Chilpancingo, Guerrero, is found in “ the mixed forest 
of oaks, pines, and firs on the high Cordillera of Guerrero above 8000 feet. It is rather 
smaller than the other forms, with a longer and more slender beak. The most 
conspicuous character is the heavy rufous shaft-lines of the feathers along the entire 
flanks, which do not become obsolete posteriorly as in the rest. The back is very dark, 
and the rump and upper tail-coverts lack the whitish mottling. The tail also is 
darker” 14, | | 
Mr. Ogilvie Grant, who has made the Game-Birds his special study, does not admit 
that the characters of these races are worthy of recognition, and we have also been 
unable, after an examination of our series of specimens, to find a confirmation of the 
facts adduced by Mr. Nelson. ‘There is undoubtedly a considerable individual variation 
in examples from the same district, due probably to the age of the birds. These 
Partridges are so rare and difficult to procure, that a much larger series is required 
before it is possible to arrive at a definite conclusion. 
Mr. Nelson (‘ Auk,’ xix. p. 388) still maintains the validity of the various races of 
D. macrurus described by him. 
We have no notes on the habits or nesting of D. macrurus.
