 generally darker and richer.

Measurements. Total length, 207; tail, 90; hind foot, 32. Skull: 

 Occipito-nasal length, 32.4; Hensel, 25.3; zygomatic width, 18;- inter-

The examples of this form were obtained in August and September, 

 mostly during the latter month, and all are in fresh pelage. Speei 

 mens of E. amoenus in the same pelage are practically indistinguishable, 

 but as a rule the Ironside examples arc darker, a deeper orange. It 

 would be interesting to know if they assume the gray pelage of amcenus 

 ai any season of the year.
