EVOTOMYS 277 



Cheek-teeth normal. Enamel of incisors orange, not pale 

 yellowish as in E. (j. isaturatus. 



For exterxul aitd cranial measurements, see table at end of 

 volume. 



Remarks. — ^Bailey says : " This species is peculiar to the low, 

 moist coast and sound region — the ' Webfoot country ' — where its 

 dark colour blends with the shadows of dense vegetation." 

 Possibly it intergrades with E. calif ornicus to the south, and with 

 E. g. saturatus of the mountains further east. E. pygmwus Rhoads 

 was based upon the young of this species.
