The Chestnut-breasted Colin belongs to the section of the genus Ortyx in which all 

 the species have a uniform rufous breast and abdomen, but a white throat. Mr. Nelson 

 has described a Colinus graysoni nigripectus from the tableland of Southern Puebla 

 (3000 to 6000 feet)i®, and another species, C. minor, from Chiapas ^^. Mr. Ogilvie 

 Grant ^ has expressed an opinion that both these forms are inseparable from 

 0. peetoralis. It seems extremely probable, from a comparison of specimens, that 

 0. nigripectus is referable to 0. peetoralis ; but of 0. minor from Chiapas we have no 

 series before us, and the identity of this form with the above-mentioned bird may 

 prove to be incorrect. In any case it can only be regarded as a small race of 

 0. peetoralis ; and Mr. Nelson's description in the 'Auk' for 1902 ^^ does not agree 

 with his original diagnosis ^^. 



Near the city of Orizaba 0. peetoralis has been found living in brush-grown and 

 weedy old fields — sometimes straying about the coflFee-plantations ^^-
