■on the back, cleai-er buffy on the sides, a bnff line edging the white 

 of the belly. Under surface pure sharply-defined white throughout. 

 Ears grey-brown, finely edged with white. Upper surface of 

 hands and feet pure white, the metapodials not darkened. Tail 

 long, very well liaired, so that the scales are nearly hidden, the 

 terminal pencil of hairs 5 to 7 mm. in length ; its colour brown 

 pi-oximally above, its vmder surface and its terminal third 

 (occasionally half) white all i-ound, though some shorter hairs on 

 the end of the tail above are also sometimes dark. 



Skvill as in Fokien specimens referred to M. confucianus^ but 

 the teeth unifoiinly larger.

This fine series of specimens is remarkably uniform, 

 thei'e being practically no variation in any important respect. 

 None of the specimens have any trace of the darker markings 

 on the metapodials found in true M. Gonfuciani(,s, nor is there 

 any material variation in the degree of whiteness of the tail. 

 Bonhote's Mus huang and 2£. ling are both much more fulvous 

 in colour, while neither they nor confucianus have the tail so 

 heavily pencilled as it is in AI. c. sacer. 



The belly of these rats would appear to be more yellow in life 

 than it is in skin, judging from the name giA^^en them by 

 Mr. Anderson. 



" Sulphur-bellied Rat. — Common among the rocks in the 

 temple-woods near Chefoo, rarely met with elsewhere. In the 

 sacred woods it feeds mostly on acorns, leaving large accumulations 

 of the shells in cavities beneath the rocks." — M. P. A.
