388 MR. J. L. BONHOTE ON THE [ Nov. 28, 
Skull (of type). Greatest length 87 mm.; basilar length 27 ; 
palatal length 15; diastema 9°5; incisive foramina 7; length of 
nasals 14; interorbital breadth 6; greatest breadth of brain- 
case 14; leneth of molar series (alveoli) 6. 
Type. B. M. 89.11.1.16. dad. Collected on the 24th April, 1898, 
at Kuatun, N.W. Fokien, by Mr. J. D. La Touche. 
Habitat. Kuatun. The Museum also contains a specimen 
indistinguishable from the type from the Ngau-tchi-lea Mts., 
Hainan. 
This species is evidently the representative of the true J/us 
jerdoni, although it is more spiny than the other members of 
that subgroup hitherto described. Its nearest ally is J/us rapit, 
mihi, from Borneo, to which it bears a very close resemblance. 
From Jus confucianus it may be easily distinguished hy its bright 
coloration, the absence of any white tip to the tail, and also the 
very much shorter hairs with which the tail is clothed. 
I have called this species from its Chinese name “ Huang mao 
shu,” meaning yellow-haired rat.

Size smaller and paler, otherwise closely resembling JZus huang. 
The amount of spininess varies considerably, some individuals 
being very thickly beset, while in others the fur is uniformly soft. 
The tail is covered with short hairs and bicoloured as the J/us 
huang, but in the young and in some adult individuals we find a 
tendency to a anicolon ous tail. The general colour is fulvous 
(ochraceous-buff, Ridgw.). 
Skull. Except for its smaller size, the skull does not differ 
markedly from that of J/us huang. The ridges referred to in 
that species may be traced as far back as the posterior margin of 
the parietal, but ave not so strongly marked. Several skulls, 
however, are intermediate in size between those of this species 
and those of Jus huang, but this Rat may in all cases be distin- 
guished externally by its paler colour and shorter tail; while m 
no case does any single measurement overlap that of the smallest 
M. huang. 
Dimensions (of type from skin). Head and body 132 mm. ; 
tail 157; hind foot 27; ear 15. 
Skull (of type). Greatest length 33 mm. ; basilar Jeng 25 ; 
palatal length 14; diastema 8°5 ; incisive foramina 5:5 ; length of 
nasals 12 ; zygomatic breadth 14; interorbital breadth 5°5 : 
greatest breadth of brain-case 14; length of molar series (alveoli)

Type. B.M. 98.3.7.8. Collected by Mr. C. B. Rickett in 
December 1897, at Ching Fen Ling, N.W. Fokien. 
Habitat. Ching Fen Ling, N.W. Fokien; it also occurs at 
Kuatun in the same province. 
This species is the representative of the eremoriventer subgroup.
