Type locality. Hursman Lake, Scriven County, Georgia. 



The type of Wagner's species is in the Universitat Institute uiid 

 Sammlungen in Zurich, Switzerland, where it was examined by Mr. 

 Osgood who says of it (/. c.) "its identity as a member of the group of 

 small mice containing the forms well-known under the names sub- 

 griseus and niveiventris is obvious. It is said to have come from 

 Georgia, and its color, which is not greatly changed by exposure, agrees 

 well with recently collected specimens from that region." 



Wagner's name will therefore take precedence of those later be- 

 stowed upon the species, its synonymy being that here given.
