The characters of the teeth separate the group from Sciurus 

 proper and the combination of characters here specified sufficiently 

 characterize it as a well-marked special group of the Sciuridae.

 p. 52 (part). 



Type, No. 26664, 9 'id., Lei-Mui-Mon, in the mountains of central Hainan, 

 Dec 31, 1902. 



Top of head, nape, sides of neck, shoulders, flanks, and outside of limbs 

 yellowish gray minutely flecked with black, the hairs individually nearly black 

 at base, then annulate^- narrowly with pale yellow and black and generally 

 tipped with yellow but some of them with black; median dorsal stripe black, of 

 variable extent, but usually extending from the shoulders to the base of the tail; 

 on either side of this a shorter light, yellowish gray stripe, of nearly the same 

 color as the nape and shoulders; exterior to this a darker, pale reddish brown 

 stripe; and exterior to this an outer pale yellowish stripe, varying in different 

 specimens from pale buff to deep buff; a short median black stripe on the nose, 

 which soon divides, a branch passing on either side to the anterior canthus of 

 the eye, and thence curving down below the buffy eyering runs to the base of the 

 ear; a broader deep buff band begins at the nose, adjoins and follows the black 

 stripe to the base of the ear and thence along the side of the neck to the shoulder ; 

 an indistinct blackish stripe below this on the side of the nose (enclosing the 

 whiskers) descends and runs posteriorly along the lower edge of the malar 

 region as far as a point opposite and considerably below the ear; these stripes, 

 in specimens with disarranged fur, appear more or less indistinct, giving to the 

 sides of the face a dingy yellowish gray effect; eyering complete, broad, deep 

 buff; ears internally buffy yellow, externally heavily clothed with soft and 

 fluffy black fur, broadly tipped with pure white; the rim of the ear is thus con- 

 spicuously edged with black relieved against white, the latter forming a distinct 

 white ear tuft; whole ventral surface and inside of limbs yellowish white, the 

 basal portion of the fur dusky; tail above mixed black and yellowish white, the 

 hairs at extreme base narrowly ringed with black, chen more broadly annulated 

 with reddish yellow and black and tipped broadly with yellowish white; tail 

 below with a broad median area of reddish yellow mixed slightly with black, 

 with a narrow border of black and an outer conspicuous fringe of pale yellow ; 

 feet grizzled yellowish gray, more yellowish on the toes. 



The skulls are unfortunately too imperfect to furnish satisfactory measure- 

 ments. Type skull, front of nasals to parieto-oceipital suture, 33; least inter- 

 orbita". breadth, 12; breadth of braincase, 17; length of nasals, 9; width 

 anteriorly, 5; posteriorly, 3; palatal length, 18; palatilar length, 14; maxillary 

 toothrow, 5.7 mm. 



Twelve specimens, all from Lei-Mui-Mon, Dec. 19, 1902, to Jan. 

 14, 1903. They are for the most part very uniform in coloration. 

 The mid-dorsal black stripe varies in length in different specimens, 

 beginning at the shoulders and running with more or less distinctness
