On the west slope of (roose Nest Mountain, just east of Little Shasta 

 Valley, Walter K. Fisher Ibund conies common in an area of slide rock 

 which extends in a ])ractically unbroken stretch from the toj) to the

Ttij)(' from I"(irt Klaiuatli, Oregon. No. i)2248, $ ad., U. S. Nat. Mtis., Biological Survey 

 Coll. Collected Jan. 25, 1898, by B. L. Cunningham. Orlg. No. 86. 



Char((ct<rs. — Similar to X. columhiensis Ehoads, but color fulvous 

 instead of yellowish, with a distinct white stripe on hind foot: skull 

 characters distinctive. 



Color. — Summer pelf I f/e: Upperparts grizzled fulvous and black, the 

 fulvous rather pale and dull, but not at all yellowish as in columhiensu; 

 head, face, and x)ectoral collar dull fulvous; chin, throat, and belly 

 white; a white stripe, sometimes irregular, extending along full length 

 of upper surface of hind foot, on inner side, and usually including toes. 

 Winter jielage: Either snow white all over, or like summer pelage 

 but with black hairs much more i)lentiful. 



Cranial characters. — Skull similar to that of cohoubiensis but some- 

 what smaller and narrower; interorbital breadth at anterior notch less; 

 bullae decidedly smaller (smallest of the amvricamis Ixdrdi iraslihuiloni 

 group); outer face of Jugalvery deeply grooved anteriorly, and with 

 upi^er ridge reaching anteriorly beyond end of groove. 



MeaHuremenlH. — Ty])e: Total leiigth. 432; tail vertebra', 28 ; hind foot, 

 127. Average of .) specimens from type locality: Total length, 410; 

 tail vertebrae, 39; hind foot, 12G. 



liemarlc.s. — Lejms liamathensis is a member of the americatui.s-hairdi- 

 7rashin(/toni grouj). In color it is intermediate between the yellowish 

 columhiensis and the dark fulvous irasliinf/toni. In cranial characters 

 it agrees best with columhiensis, particularly in the great length of the 

 IK)storbital processes, but in the small bulhe and peculiar form of the 

 jugal it dilfers from all known m(Mid)ers of the groni>. 



This rabbit is common in the alder thickets in marshy i)laccs and 

 along streams near Fort Klamath. Oregon, from which place the late 

 IVIaJor Chas. I'], liendiie sent me several specimens in the winter of 

 1883-84; and from which we have recently obtained additional spec- 

 imens from I>. L. Cunningiiam.
