Habitat. Only recorded from W. and N.W. Fokien. 
The first specimens of these Rats were all obtained high up on 
the mountains among rocky ground, in the erevices of which it 
lives. Beyond this, nothing is known of its habits. It has only 
been taken in W. and N.W. Fokien.

Mus coninga (ander which name it was originally described by 
Swinhoe) is undoubtedly a Rat of the jerdoni type (rajah sub- 
group), and not the jerdoni subgroup as noted by me. The typical 
form, as described by Swinhoe, has the upper parts reddish brown, 
sprinkled with stiff black bristles, especially on the back, where 
the fur is also often a little darker. Under parts pure white; 
feet white; tail bicolor, white at the tip. 
The skulls at my disposal are too fragmentary to allow of a 
description. 
Dimensions (from skin). Head and body 208 mm. ; tail 180; 
hind foot 36. 
Skull. Palatallength 19 mm.; diastema 11; incisive foramina 7; 
length of nasals 17; interorbital breadth 6:5; length of molar 
series (alveoli) 8 mm. 
Habitat. Formosa. 
Swinhoe noted many varieties of this species as occurring in 
Formosa; these doubtless represent forms belonging to the 
different subgroups of the jerdoni group, but unfortunately the 
only specimens I have been able to examine are a portion of 
Swinhoe’s series of which the skullsare all defective. It is there- 
fore impossible to distinguish any of these varieties by name; but 
the true coxingi may be distinguished by its white feet, the white 
tip to its tail, and the fact that the fur is thickly beset with 
spines.

General colour above dark brown (clay, Ridgw.), shading to 
pale buff or yellowish on the flanks. Fur slate-grey at the 
base with pale fulvous tip, interspersed amongst which are long 
black bristles. The pale tips predominate over the black so as 
to give the animal the appearance noted above. Occasionally these 
bristles are semi-spinous, and in one or two examples the fur is 
exceedingly harsh and spiny; but as a rule it is quite soft to the
