M Gadow {op. cit., p. 358) states that Peters's cotypes are immature and therefore not readily placed. The 

 original description is of little assistance. We do not follow Gadow's allocation of the name, with a distinct 

 southern race, for two reasons: (1) The name can simply be disposed of, if the types are unidentifiable, by 

 placing it in synonsrmy; and (2) we believe it quite probable that the types actually came from southwestern 

 Puebla in the Balsas Basin, where a number of Peters's species are known to be restricted. This latter area 

 is occupied by C. s. sackii, of which Peters's name can reasonably be held a synonym.
