Varieties and Distribution —Of the present species, four geographical 
varieties are recognized, namely: hudsonius, richardsont, douglass, and 
fremontt. These are sufficiently distinct in their extreme phases, but are 
very much blended wherever their respective habitats weet; the sub- 
species are readily separated by their coloration, especially the tail — 
markings.
