Remarks^ — Color is much less important than size for the char- 

 acterization of this race, and particularly for the identification of 

 specimens, because such color differences as exist are not very

 to these measurements as to those of Hedymeles melanocephalus melanocephalus, for which 

 see footnote on page 409.
