This is the animal carefully described by Professor Baird in 1S58 as C. 

 mexicamis, 6m.; but he applied this name provisionally, remarking that 

 there was some doubt whether it was the true C. mexicamis of authors or not. 

 According to the descriptions, the C. mexicanus, to which is ascribed a range 

 from Mexico to Brazil, appears to be distinct from C. virginianus ; but the 

 present animal is beyond doubt only a small southern form of that wide 

 ranging species, to which it must unquestionably be referred. Br. Rothrock's 

 specimens fix its characters with the desired precision ; but further compari- 

 sons with more material from Mexico and Central America will be required 

 to establish its relationships to the small deer of those countries. Should it 

 prove distinct from these, it may bear the name applied to it in 1 >r. Rothrock's 

 MSS. ; but at present we are indisposed to formally recognize this designa- 

 tion. 



The foregoing account ma}' be properly supplemented by the notice 

 published recently by Dr. Rothrock in the "American Sportsman," which 

 gives measurements taken in the flesh, and various interesting particular- res- 

 pecting the general appearance and habits of this deer.
