MAMMALS-TALPIDAE-UROTRICHUS GIBBS1I.

but much longer than the 1st and 5th, the claws of which reach, respectively, to the bases of 
those of the 2d and 4th; the first digit and claw consequently shorter than the fifth. 
The tail is long; with the hairs, but little shorter than the body, exclusive of the head. It is 
constricted at the base, thickened somewhat in the middle, and tapers gently to the extremity. 
It is covered with annulated scales, which, however, are much obscured by the long bristly hairs 
which spring from between the annuli, and tip the tail in a stiff pencil. 
The color is a dark sooty-brown, almost inappreciably lighter beneath. The color almost 
uniform from the roots ; a little more bluish, perhaps, in the covered portion. Some of the hairs 
are more lustrous than others, and reflect light so as to impart a hoary appearance. The fur is 
long and not very compact. The longest hairs measure about 0.20 of an inch. 
I regret very much that the skull of the only specimen I have seen is much broken, and at the 
same time so immature that the permanent teeth have not yet fully taken their places. As far, 
however, as I can make out, the skull is broader, and narrows anteriorly rather more abruptly 
than in Scalops. The nasal bones extend as far as the anterior edge of the upper incisors, as in 
Scalops, not Gondylura . There may be made out an anterior scalpriform incisor, broader than 
in Scalops, and projecting downward; and behind this two smaller ones of similar shape. The 
permanent canine is not distinguishable unless this be indicated by the emerging crown of a tooth 
apparently with two roots. The premolars have each two roots. The molars are three in 
number. 
The lower anterior incisor is much as in Gondylura, broad, horizontal, and half spoon-shaped.

The only specimen hitherto obtained of this species was collected by Mr. George Gibbs, of 
Steilacoom, and by him presented to Dr. Suckley. 
This animal appears rather smaller than the Japanese U. talpoides, as described by Temminck. 
The feet and tail are proportionally larger. The color of U. talpoides is maroon-brown.
