P. Hewitsoni, Moore. The blue area as large as in the 
former, occupying the entire discoidal cell of the fore wing, 
and in the submedian interspace all but reaching the outer 
margin. ‘There are two blue apical spots as in Hewitsoni, 
but no black spot in the submedian interspace as in most 
specimens of that species, nor even the black line on the sub- 
median vein as in typical pleurata. In the hind wing the 
blue area occupies the discoidal cell and extends a little above 
the radial. The outer margin of the hind wing is narrowly 
black, and there are, as in pleurata, traces of marginal and 
submarginal rows of black markings. 
Below, the markings much resemble those of pleurata, but 
are more indistinct, more parallel, and on a pale ground. 
X.— Description of a new Rat from China. 
By OLprFieLp THOMAS. 
AMONG a collection made at Kuatun, N.W. Fokien, and 
presented to the National Museum by Messrs. J. de La Touche 
and C. B. Rickett, there occur three specimens of a fine large 
rat as large as Mus Hdwardst, Thos., found at the same 
locality, but quite different from that and more nearly allied 
to the Burmese Mus Bowersi, And. It is, however, clearly 
distinct, and may be called 
Mus Latouchet, sp. n. 
Size very large. Upper surface uniformly clear grizzled 
grey, without tinge of yellow; the fur composed of grey 
hairs intermixed with slender, flattened, white, brown-tipped 
spines, not numerous or stiff enough to make the fur feel 
really spinous. Under surface pure white or yellowish white 
throughout, the line of demarcation on sides not very sharply 
defined. Kars large, evenly rounded. Hands white above, 
the fingers almost naked. Feet greyish proximally, white on 
the digits. Tail about as long as the head and body, its 
scales averaging about ten to the centimetre, very thinly 
haired, uniformly brown above and below, the extreme tip 
white. 
Skull, in proportion to the size of the animal, rather lightly 
built. Compared to that of Mus Bowers¢ the nasals are more 
square-ended behind, the line of the fronto-premaxillary and 
fronto-nasal sutures 1s straight across from side to side
