Mr. Nelson recognizes four races of JJactylortyx thoracicus, as follows: true 



I), thoracicus (Gambel), from the mountains of Eastern Mexico ; B. thoracicus lineolatus 

 (Gould), from the mountains of South-western Oaxaca and the adjacent part of 

 Chiapas ; B. chiapensis, from San Cristobal, Chiapas, and the Volcan de Santa Maria 

 Guatemala; and, lastly, B. devius, from the forests of Jalisco, and probably other parts 

 of Western Mexico.
