 46.4. 



Size. Old adult $ (topotype, No. 3052, Bangs coll.) : total length, 719 ;

General remarks. Mephitis elongata is very different from M. mephitica, 

 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.
