Plateau -Ret/ion of Arizona. Ill 



P. Streator (No. 53517, United States National Museum, Depart- 

 ment of Agriculture collection) has the under parts stained a 

 deep salmon pink from the soil. This color washes out, leaving 

 the belly pure white as in the Reams Canon specimens. 



Gco</r<ii>/ii<' Distribution and Faunal Position. Neotoma arizonae 

 inhabits the Tusayaii or Moki district in eastern Arizona, and 

 adjacent parts of the Painted Desert on the west, and New Mexico 

 on the east. In all, eleven specimens have been examined: 

 eight from the Moki country, one from Winslow in the Painted 

 Desert, one from Tres Piedras in northern New Mexico, and one 

 from Fort Wingate, near the western border of New Mexico. 

 The species evidently belongs to the Upper Sonoran zone. 



Neotoma pinetorum sp. nov. 



Type from SAN FRANCISCO MOUNTAIN, ARIZONA. No. \HH $ad. United 

 States National Museum, Department of Agriculture collection. Collected 

 by Vernon Bailey August 16, 1889 (original number, 366). 



Measurements of Type Specimen (taken in flesh). Total length, 355; tail 

 vertebrae, 163 ; hind foot, 37 ; ear from anterior base, 25 (measured in. dry 

 skin). Average measurements of four adult specimens total length, 362 ; 

 tail vertebse, 166 ; hind foot, 36.7. 



General Characters. Similar to N. fuscipes from southern Cali- 

 fornia, but averaging slightly smaller ; tail, ears, and hind feet 

 shorter ; tail more hairy ; hind feet pure white [not clouded with 

 dusky as in N. fuscipr*] ; back more strongly suffused with ful- 

 vous ; whiskers long, reaching shoulders. 



Color. Upper parts fulvous, strongly mixed with black-tipped 

 hairs; face from nose to above eyes gray, slightly grizzled, color 

 of upper parts stopping at (or above) wrists and at ankles ; 

 under parts and feet white; tail sharply bicolor, above blackish, 

 below white. Other specimens are less strongly fulvous, and the 

 young are gray. 



Cranial and Dental Characters. Skull similar to that of the 

 southern form of N. fuscipes but broader; brain case broader and 

 shorter ; palate and inter-pterygoid fossa longer ; teeth larger 

 (both molars and incisors). 



General Remarks. In my report on the mammals of San Fran- 

 cisco Mountain, Arizona, I referred the wood rat of the region to 

 Neotoma mexicana of Baird.* At that time no typical specimens 

 of mexicana were available for comparison. Since then, however, 

 14 specimens have been secured from the type locality. Chi- 

 huahua city, Mexico.
