392 MR, J. L. BONHOTE ON 'THE [ Nov. 28, 
Habitat. This species was originally described from Tamsuy in 
Formosa. But there is also a specimen collected by Mr. Swinhoe 
at. Amoy, and other specimens in the Museum from W. Fokien. 
This is undoubtedly a small form of J. flavipectus, distin- 
guishable, apart from its size, by the more elongated ear and finer 
annulations to the tail. 
It is possible that the original losea from Formosa may prove 
to be different from the form inhabiting the mainland; and this 
is the more likely, as in the paper describing the original losea 
Mr. Swinhoe referred to the specimen from Amoy as Mus rufescens. 
For the present, however, owing to lack of material, | have no 
alternative but to consider them all as Josea.

id. Rech. Mamm. p. 290, pl. 42. fig. 2 (1874). 
Similar to I. flavipectus, but slightly larger. Tail about 
equal in length to the head and body. Fur soft and destitute of 
spines. General colour above yellowish brown; fur slate-grey at 
base, with yellowish tips, and thickly interspersed among these 
are longer thin black hairs, which predominate along the median 
flovsal area. Upper surfaces of the feet and hands white. Under 
parts white or greyish, the fur being dark at its base as in the 
upper parts. 
Skull. The skull, except in being slightly larger, closely re- 
sembles that of IZ. favipectus, and calls for no special comment. 
Dimensions. Head and body 196 mm.; tail 160; hind foot 33 ; 
ear 22. 
Skull. Greatest length 45 mm.; basilar length 36; palatilar 
length 22; diastema 13; length of incisive foramina 8; length 
of nasals 17; zygomatic breadth 21:5; interorbital breadth 7; 
breadth of brain-case 18; length of molar series 8. 
Habitat. Sze-chuen (type-locality); also found in W. Fokien. 
There is but little further to add with regard to this species. 
It is most likely to be confused with J. flavipectus, but the 
characters distinguishing it from that species have already been 
given. There is, however, another small character which it may 
be as well to notice. In J/. flavipectus the hands on their upper 
surfaces are brown margined with white, while in all the specimens 
of griseipectus that I have examined the upper surfaces of the 
hands are uniformly white.
