General remarks. — Mephitis elongata is ver\' different from ^[. ntephiticu, 

 and its characters are constant throughout its range. Since I can find no 

 indication of intergradation and the ranges of the two forms are sepa- 

 rated, at least in the east, by a strip of neutral ground, where no skunk 

 occurs, M. elongata seems entitled to rank as a full species.
