MONOGRAPHS OP NORTH AMERICAN RODENTIA. 



as the fragments show, arc a little lighter brown than most of Mr. Goss' 

 late v/inter and early spring skins, especially No. 1368, which has also the 

 tail more distinctly bicolor than it is in these. But some of the Kansas ones 

 are identical in color with the types ; and they vary as much among them- 

 selves in color as some of tiieni do from Nos. 1367-8. The tails of all, except 

 No. 1368, are not evidently bicolor. The under parts are hoary-ash, usually 

 soiled, especially across the abdomen, with pale muddy-brown, somewhat as 

 in ji. austcrus, but not approaching the cinnamon shade that the latter fre- 

 quently exhibits. The tail and feet in dried skins are dark fuscous ; in alco- 

 holic species light brown, with a flesh-colored shade. The incisors are yellow, 

 as usual ; the claws brownisii-white. Besides the copious long fine pelage 

 of this animal, there seems to be something peculiar in the tenderness of the 

 skin itself; the feet are detached almost at a touch, so that the labels cannot 

 be secured in the ordinary way. The following table shows to some extent 

 the range of variation in size: —

* But the loDgtli olhead and iMMly and of tail areas taken in thollesliby Mr. Ooss for \os. 8308-13, Ho seems to hare 

 taken tbe tall-meaf)nrcment further up tbo ooooygoal Torteiirto than is Rencraliy done, no that the tails as fit^'on eqnal that 

 of No. I;«i8. wliereaA they are certainly shorter. Our luOAsuremenls of the dried tail, did we make any, woulil nin fully 0.10, 

 if not 30, ioHN than Mr. Go:*8' ll((nres. Onr measurements of tho alcoholic speclmeus are the most reliable of the series. 

 Nub. 8516, 8517, are not full grown. 



t In No. 990.'l, apparently a nurnihg female, we find two pairs of pectoral mammn) and one pair of inguinal mamm», 

 vitltoot being nblo to make out any interventug ventr.il ones. It la probable, however, that tbo species posoosses a Tontral 

 pair, making oi|;ht teats in all.
