232 SOME CHINESE VERTEBRATES. 
feet are seal-brown to blackish above, the former with a very slight admixture 
of ochraceous hairs. 
Ventrally the colors are richer and darker than in consobrinus, the dark of 
the sides encroaching nearly to the mid line of the venter and on the inside 
of the limbs. Chest and mid ventral area washed conspicuously with tawny- 
ochraceous; the bases of the hairs slaty. Median area of the throat pure white. 
The basal fifth of the tail is colored above like the back; the rest is nearly 
clear tawny with a black border and an outer fringe of white. The ventral 
surface is similar but the tawny median area is partly obscured by long black 
hairs tipped with white. 
Measurements:— The type was measured in the flesh by the collector as 
follows:— total length, 363 mm.; tail, 148; hind foot, 54. 
Remarks:— This very well-marked race will probably prove to be confined 
to the Washan Mountains, whose peculiar conditions and isolation seem to have 
induced the differentiation of a number of local races or species. Unfortunately 
the skull of the type was lost, and no other specimens were obtained. It appears, 
however, to be sufficiently well characterized for recognition, and I have named 
it in honor of Col. John E. Thayer through whose generosity the collection was 
made possible. 
TAMIOPS MACCLELLANDI SWINHOEI (Milne Edwards). 
A single specimen of this prettily striped species was collected at Tachiao, 
western Szechwan, September 20, 1908, at an altitude of 12,000 feet. 
Milne Edwards based his description on specimens from the “principauté 
de Moupin.”’ Our specimen is thus practically from the same locality, and since 
I have found no good description of the species I append the following particulars. 
Forehead and crown a grizzled gallstone-yellow and black; nape, shoulders, 
flanks, and upper side of limbs olive becoming lighter on the sides and passing 
into raw umber on the rump. Five black stripes on the back, the median dorsal 
beginning on the nape, becoming broadest in the middle region of the back, then 
narrowing to the base of the tail. A shorter but equally broad black stripe 
on each side from shoulders to rump, the intermediate space clay color. A broad 
clear stripe of pale ochraceous succeeds this black stripe laterally, on either side 
and is bordered by a short and ill-defined blackish line; inner surface of the 
ears pale ochraceous, outer surface bordered by black and provided with an 
erect fringe of long white hairs. A buff line runs from the muzzle, below the 
eye to the posterior base of the ear, and there is a narrow eye-ring of the same
