Description. — Similar to Neotoma mexicana, 

 but much larger, and of a darker, more ful- 

 vous color on the upper surface. Length, 

 360 mm.; tail vertebrae, 160; hind foot, .37; 

 ear from crown, 25. Skull, 47 by 24 (adult 

 male from Baker's Butte, Yavapai County,

 black-tipped hairs; under surface and feet, 

 white; tail black above, white below; sides of 

 face, grayish. 



Cranial and dental characters. — The skull and 

 teeth (figs. 121 and 122), though much heavier 

 than in Neotoma mexicana, have much the 

 same character. The interpterygoid space is remarkably long and 

 narrow. 



RemarTcs. — This species does not reach the Mexican Line, but was 

 included in my earlier collections, made in Arizona from 1884 to 1888. 



TIabits and local distribution. — This rat builds large nests in thickets 

 and stumps of trees. It enters houses freely. At Bakers Butte 

 (altitude, 8,000 feet) I trapped a specimen in a cabin; and the species
