SCAPANUS LATIMANUS ALPINUS Merriam. 

 Mount Mazama Mole. 

 Scapanus alpinus Merriam, Proc. Biol. Soc. Washington, vol. 11, p. 102, April 26, 1897. 



Type locality. — Crater Lake, Mount Mazama, Klamath County, 

 Oregon; altitude about 7000 feet. 



Type specimen. — No. 79967, U. S. Nat. Mus., Biological Survey 

 collection; c? adult, skin and skull; collected August 18, 1896, by 

 Vernon Bailey. 



GeograpTiic range. — Known only from type locality. 



General characters. — ^About the size of large specimens of S. I. lati- 

 manus, but much paler; hind foot large; indistinguishable in color 

 from S. I. dilatus, but larger; skull like that of large specimens of 

 latimanus, and much larger, flatter, and relatively longer and narrower 

 than that of dilatus. 



Color. — Worn summer pelage (type).* Upperparts mouse gray: 

 underparts (much worn) deep mouse gray; faded unworn pelage on 

 throat and chest with a distinct buffy sheen. 



ShuU. — Similar to that of S. I. latimanus; indistinguishable from 

 skulls of large adult males of latimanus. 



Measurements. — Type (adult male): Total length, 188; tail verte- 

 brse, 38; hind foot, 24.5 STcull: Type (adult male): Greatest length, 

 36.9; palatilar length, 14.6; mastoidal breadth, 17; interorbital 

 breadth, 7.9; maxillary tooth row, 11.4; mandibular molar-premolar 

 row, 11.3. 



RemarTcs. — The subspecies alpinus is a poorly differentiated form 

 having the color of 8. I. dilatus and the size and skuU proportions of 

 large specimens of S. I. latimanus; it is not strictly intermediate 

 between these two forms, however, since specimens of latimanus 

 from southwest of Klamath Lake do not reach the maximum size. 

 The type is a very old male with much-worn teeth; the skull is flat- 

 tened by age and the cusps of the teeth are reduced through wear 

 and absorption. 

 • Specimen examined. — One, the type.
