Mus. 331 
The following are doubtful species :— 
No. 348. Mus PLURIMAMMIS. 
Jerdon's No. 177. 
This, which Blyth considered a good species, is, I am informed, 
referable with AZ. Zaraiyensis and M. Morungensis to Gray’s Wesokia 
Bengalensis. ‘The type and drawing of it are in the British Museum. 
No. 349. MUS AQUICAUDALIS 
of Hodgson, described in Horsfield’s Catalogue as pure dark brown 
above, with a very slight cast of rufescent in a certain aspect; under- 
neath from the chin to the vent, with interior of thighs, yellowish-white ; 
ears nearly an inch long ; head proportionately long (‘ Ann. and Mag. 
Nat. Hist.’ new series, ill. p. 203). This, with Blyth’s JZ nemoralis, 
seems identical with JZ. brunneus. 
Mus arboreus of Horsfield’s Catalogue is us rufescens. It remains 
to be seen whether there is sufficient difference between JZ. rufescens 
and JZ. niveiventer to warrant the separation of the latter as a distinct 
species. 
The following species lead on to the mice—beginning with the long- 
tailed arboreal species, Vandeleuria of Gray, which connect the arboreal 
rats with the house mice. : 
The characteristics of Vandeleuria are: upper incisors triangular, 
grooved in front ; ears hairy ; fur soft, with long bristles interspersed ; 
long tail, sparsely haired; hind feet very long, slender; soles bald 
beneath; toes ‘45 long, slender, compressed, the pads much more 
strongly developed than in ground mice; the inner and outer toes with 
a small flattened nail. 
No. 350. Mus OLERACEUS. 
The Long-tailed Tree Mouse ( Jerdon’s No. 184). 
Native Names.—Marad-iei, Canarese ; Meina-yelka, Telegu of the 
Yanadees ( Jerdon). 
Hasirat.—Throughout India from north to south, but has not been 
reported from Ceylon. In Burmah Dr. Anderson found it in the valley 
of the Nampoung, a frontier stream dividing Burmah from China. 
DEscRIPTION.—Upper surface rich rufous or chestnut red, paling to 
brown on the*ears and muzzle before the eyes; under-parts white, with 
a yellowish tinge ; feet pale brown, shading off into white on the toes ; 
under surface of feet yellowish ; tail brownish or dusky with grey hairs ;
