Mr. J. K. Lord on two new Mammals. 95 
shadow of an attempt to construct one, was there to be seen. Early 
in October I returned again by the trail I had used in going from 
Fort Colville to Fort Hope; the snow had fallen to about the depth 
of 6 inches, completely covering up the rocks and stones. All the 
little fellows had disappeared, and, although I searched most care- 
fully, there was not a hole nor track in the snow to show they had 
ever left their quarters. It was quite impossible a nest could have 
been made in the interim ; hence I feel perfectly sure they hybernate 
in deep holes without a nest, whereas Lagomys minimus, living at a 
much greater altitude, makes a large nest of hay to pass his winter 
sleep in. : 
The two new animals may be described as follows :— 
Frser osoyoosensis, Lord, sp. nov. 
Sp. char.—In total length 33 inches shorter than Fiber zibethi- 
cus (Cuv.) ; in general size much smaller. General hue of back jet- 
black ; but, the hair being of two kinds, if viewed from tail to head it 
looks grey—the under fur being fine, silky, and light grey in colour ; 
concealing this on the upper surface are long coarse black hairs ; the 
belly and sides somewhat lighter ; head broad and depressed ; neck 
indistinct ; ear small, upper margin rounded ; eye small and black ; 
the feet, legs, and claws are so exactly like those of Fiber zibethicus 
that it would be useless to describe them again ; whiskers long, and 
composed of about an equal number of white and black hairs ; inci- 
sors nearly straight, on the external surface orange-yellow. 
The skull differs from Fiber zibethicus in being much smaller, 
21 inches in length, 14 inch in width, very much shorter from the 
anterior molar to incisors ; nasal bones much more rounded at their 
posterior ends, the superior outline less curved ; postorbital process 
not nearly so much developed; the cranial portion of the skull in 
its upper outline is much less concave, and smoother ; superior out- 
line of occipital bone not so prominent or strong; incisors shorter 
and much straighter; molars much smaller, but in general outline 
similar. 
Lacomys MINIMvs, Lord, sp. nov. 
Sp. char.—Differs from Lepus (Lagomys) princeps of Sir J. 
Richardson (F. B. A., 1. p. 227, pl. 19) in being much smaller. Pre- 
dominant colour of back dark grey, tinged faintly with umber-yellow, 
more vivid about the shoulders, but gradually shading off on the 
sides and belly to dirty white ; feet white, washed over with yellowish 
brown ; ears large, black inside, the outer rounded margin edged 
with white ; eye very small and intensely black ; whiskers long, and 
composed of about an equal number of white and black hairs. 
Measurement: Head and body 63 inches; head 2 inches; nose 
to auditory opening 17 inch; height of ear from behind 1 inch. 
The skull differs in being generally smaller ; the cranial portion 
of the skull in its superior outline is much narrower and smoother. 
The nasal bones are shorter and broader, and rounded at their poste- 
rior articulation, instead of being deeply notched as in L. princeps.
