 parison is required. Contrasted with the skull of E. alpinm from the 

 High Sierra of California, the skull is slightly larger, the frontals decidedly 

 narrower between orbits; parietals longer; rostrum blunter and much 

 more swollen ; teeth disproportionally larger, especially the molars.

 breadth, 18; palatal length, 15.5 ; upper molar series on crowns, 5.
