This Spermophila has a wide range in South America. I can- 

 not distinguish skins from Panama, Western Ecuador, Bogota, 

 Para, aud Rio now before me. Natterer, as will be seen from 

 my list of localities, met with it still further south.

 Honduras {Whitely) ; Nicaragua (Kennicott) ; Costa Rica 

 {Carmiol et Arce); Panama {M'Cleannan). 



This seems to be a common species throughout Centi^al 

 America from Southern Mexico to Panama. I have always 

 expected to find an earlier name for it than my own, but have 

 not yet succeeded in doing so. 



Prof. Baird has most kindly sent me the type of 5. badiiventris 

 for examination ; but 1 am unable to see in this specimen any-
