l>rOETH AMEEICAN FAUNA. 



[No. 38. 



slightly paler than back, more silvery and showing less buff -pink; 

 base of hairs deep neutral gray. Young: More plumbeous than 

 adults, darker, less pink-buff tinge on back and little or no ochraceous- 

 buff on nose and wrists. 



SlcuU. — Resembles that of S, a. caryi in nearly every particular, 

 but averages slightly larger, is usually slightly more depressed post- 

 orbitally, and has relatively heavier molariform dentition. 



Measurements. — Average of 4 adult males from type locality: 

 Total length, 164.5 (160-169); tail vertebrss, 28.8 (27-31); hind foot, 

 21.8 (21-22). SJmll: Average of 4 skulls of adult males from type 

 locality: Greatest length, 35 (34.5-35.6); palatilar length, 14.7 (14.5- 

 14.9); mastoidal breadth, 18.3 (17.8-18.5); interorbital breadth, 8.1 

 (7.8-8.3); maxillary tooth row, 11.4 (10.9-11.7); mandibular molar- 

 premolar row, 11.1 (10.5-11.4). 



Remarks. — The subspecies intermedius can be distinguished from 

 its nearest congener, S. a. caryi, by its slightly darker color, and, in 

 full adult pelage, by the ochraceous-buff or zinc orange on nose and 

 wrists ; the skull of intermedius is generally longer than that of caryi. 

 Specimens from Mount Scott, Okla., are a little darker than typical 

 intermedius, and the skulls are slightly longer. Intergradation 

 between this subspecies and S. a. texanus apparently occurs in north- 

 central Texas. It seems probable that intermedius intergrades also 

 with S. a. pulclier in eastern Oldahoma, though specimens from Red 

 Fork, Okla., show no approach to pulcJier. An alcoholic specimen 

 from Belknap, Tex., too yoimg for positive identification, is provis- 

 ionally referred to intermedius. 



Specimens examined. — Total number, 22, as follows: 

 Oklahoma: Alva (type locality), 6; Dougherty, 1; ^ Fort Reno, 1; Mount Scott, 



5; Red Fork, 3. 

 Texas: Belknap, 1; Lipscomb, 3; Mobeetie, 2.
