NORTH AMERICAN FAUNA. 



[No. 38. 



of macTirinoides; and the rostrum is slightly heavier than that of 

 typical pulcher, but in size and other characters it is very similar to 

 skulls from the type locality. The specimen is in very fresh spring 

 pelage, a little of the winter fur remaining on nose and rump, and in 

 color it seems to be more nearly like rnuchrinoides than pulcTier. A 

 specimen from Fort Smith, Ark., and one from Wister, Okla., neither 

 adult, are referable to pulcher.

Arkansas: Camden, 1; Delight (type locality), 15; Lake City, 1; Fort Smith, 1; 

 Wilmot, 1. 



Louisiana: Clarks, 1; Columbia, 1; ^ Grand Coteau, 1; Mer Rouge, 23; Natchi-

Scalopus aquaticus caryi Jackson, Proc. Biol. Soc. Washington, vol. 27, p. 20, Feb- 

 ruary 2, 1914. 



Type locality. — Neligh, Antelope County, Nebraska. 



Type specimen. — No. 116799, U. S. Nat. Mus., Biological Survey col- 

 lection; J young adult, skin and skull; collected September 18, 1901, 

 by Merritt Gary. 



Geograpliic range. — ^Arid and semiarid pla^ins region of central and 

 western Nebraska, northeastern Colorado, and northwestern Kansas. 



General cliaracters. — Size medium; tail long; color palest of the 

 genus; most nearly like 8, a. intermedins but much paler and lacking 

 ochraceous suffusions on nose and wrists; skull slightly shorter than 

 that of intermedins and relatively broader interorbi tally. 



Color. — Autumn pelage: Back light drab slightly tending toward 

 avellaneous, becoming paler on head and shading in some cases into 

 ivory yellow on nose; underparts much the same color as back, more 

 mixed with neutral gray and occasionally washed with Saccardo's 

 umber or cinnamon-brown. 



SJcull. — Size moderate, short, broad, and rotund; rostrum short; 

 mandible heavy; dentition relatively heavy. Very similar to the 

 skull of 8. a. intermedius but slightly shorter and relatively broader 

 interorbitally. Compared with the skull of 8. a. pulcTier that of 

 8. a. caryi is shorter and higher, wider interorbitally, and has weaker 

 mastoids, shorter, wider rostrum, and larger teeth; it is larger, much 

 higher, and more massive than the skuU of 8. xreus, and is much 

 smaller, higher, and less angular than that of 8. a. macTirinoides,
