THE GEOGRAPHIC RACES OF THE SCALED QUAIL. 
BY OUTRAM BANGS. 
THE monotypic genus of American partridges, Callipepla, for 
many years has been universally regarded by ornithologists as 
containing two geographic races only. A study lately made of the 
series in the Museum of Comparative Zodlogy, however, has con- 
vinced me that three instead of two subspecies must be recognized. 
These briefly are as follows:— 
Callipepla squamata squamata (Vig.). 
Ortyx squamatus Vigors, Zool. Journ., Vol. V, 1830, p. 275, “Mexico.” 
Range.— Valley of Mexico, from San Louis Potosi south to near City 
of Mexico, and north probably to southern parts of Coahuila and Chihua- 
hua. 
Characters.— Breast and upper back distinctly plumbeous gray, very 
much darker than in the next form; lower back and rump dark smoke- 
gray; belly, especially in the male, strongly suffused with yellowish brown. 
Remarks.— Of this form I have examined but four skins, two 
males and two females from San Louis Potosi, collected by Dr. 
Edward Palmer. These, however, are so strikingly different from 
the pallid birds of farther north that they cannot be regarded as 
belonging to the same subspecies.
