M. nurescens, Gray, apud Gray (flavescens, Elliot), from Penang, 
on the authority of Cantor; and M. musounus (?) apud Cantor, from 
Penang. We possess two specimens from Malacea, which bear con- 
siderable resemblance to each other except in size; but one is cer- 
tainly not the young of the other, as shewn by the comparative size 
of the feet. Had they been of the same species, the feet of the small- 
er specimen would have been considerably larger. The larger of the 
two is perhaps the young of M. seTIFER; measuring about 64 in. 
long: tail 5} in.: hind-foot 1,4 in.: auricles of medium size, naked: 
tail with close rings fringed with short sets: fur rather coarse on the 
upper parts, approaching to the spinous character, and the soft un- 
der-fur not shewing at the surface ; of an uniform yellowish rufescent 
brown above, a little paler below, passing into dull albescent on the 
throat: the whiskers reach to beyond the ears, and are of a shining 
dark brown colour ; and there are only a few fine long hairs protruding 
beyond the general surface of the fur of the back; the smaller speci- 
men appears to be the young of M. RopusTULUS, nobis, and is doubt- 
less the M. RuFEScHNS apud Cantor; but its fur tends somewhat 
unusually to be weakly spinous. The general colour is of a dull 
murim-brown above, slightly albescent below, passing to dull white 
on the throat. Length of head and body about 43 in.; and of 
hind-foot 1% in., Mws setifer is included in M. ? of H. L. Layard’s ‘ List 
of the Mammalia observed in Ceylon,’ Ann. Lag. N. H., 2nd series, 
VII. (1851), p. 405; but not in Dr. Kelaart’s Prodromus Faune.* 
Mus pecumanvs, Pallas, Glires, 91; Buffon, H. NV. VIII. ¢. 27: 
MM. javanus, Pallas, apud Schinz, JZ norvegicus, Buffon. To this 
species Dr. Gray refers (with a mark of doubt), in his Catalogue of 
Mr. Hodgson’s collection, the Jf. decumanoides, Hodgson, (nec Water- 
house, nee Horsfield), which does not appear to have been described ; 
also MZ. brunneus, Hodgson, Ann. Mag. N. H. XV. (1845), 267; 
described as follows ; 
‘Mus brunmeus, H. Common house rat of Nepal. As nearly allied to decu- 
MANUS AS Nemorivagus is to the Bandicoot, [%. e. identical]; above rusty-brown ; 
below rusty, more or less albescent. Hxtremities pale, fleshy-white nearly. 
Tail barely longer than the head and body. Long piles sufficiently numerous, 
* Another species has been (or is to be) described from those islands, by the 
same naturalist, as M. pALMARUM. I have not seen any description. The name 
would indicate the habits of Mus rurescens.
