 T. KANCHiL, Raffles. 

 The smaller mouso-dcer. 



Colour rufous or dark rufous, witli a dark mesial .stripe on tlic chrst, bordered witli 

 ■white. Size that of a hare. 



llanges from the ilahiy eountries into Tenasserim. 



T. NAPTJ, F. Cuv. 



The larger mouse doer. 



Much lari^rr and stouter (lian tlio last. Colour brown, with a dark stripe down 

 the back of the neck, and five white stripes below the throat. Eelly white. 



R:uif;es inlo Tenasserim with tlie last, but is less common than it. 



Mr. BUmfurd tlius contrasts these two s])ecies: — 



" As was suggested by Blyth in liis remarks on Tragulm kanchil, the larger form 

 of chevrotain is found in Southern Tenasserim, Mr. Daviscm liaving procured an adult 

 find a young animal from Bankasiin. Owing to tlie e.ttremo confusion which formerly 

 prevailed as to the synonymy of tlie Tniyuli, tlie nomenclature and distribution of the 

 different species cannot be said yet to be rightly determined in all cases, but it is clear 

 that two d.istiuct forms arc found in the Tenasserim provinces, and tliese forms appear 

 to be the T. kanchil and T. napu of A. Jklilne-Edwards' monogiaph of the Tragulidm 

 in the ' Annales des Sciences Naturelles,' as has already been pointed out by 

 Mr. Blyth. 



" The most striking differences between the two species are, — first, size ; T. napu 

 being probably thrice the weight of T. kanchil; — second, the much stouter limbs of 

 the former; the leusth of the tarsus and liind foot in two specimens before me of 

 'I. napu and T. kanchil respectively being 5-8.'> and 4-8, whilst the cireumfereneo of 

 each tarsus in the middle is 1-3 and 0-85; — and, third, colouration, especially below. 

 There is but little difference above; both aiv. brown, becoming ])aler and greyer on 

 the sides, but the dark line from the najie down the back of the neck is much more 

 distinct in T. kanchil. The colouration of the throat and belly, however, is very 

 diiferent ; in T. napu there are five white strijies on the throat, one longitudinal in 

 the middle, and two obli(|ue striprs on eaeh side, the upper lateral band being much 

 shorter than the lower. In the adult skin from Tenasserim all these bands unite in 

 front, but not in the young s])ecimcn, in which the median strii)e is separated from 

 the others, as described by Milne-Edwards. The interspaces between the white 

 bands are dark brown, darker than the sides of the neck, but this ajipears sometimes 

 to be the case in T. kanchil also. The abdomen in adult T. napu is mostly white, the 

 breast and the space between the thighs jmrcr white than the rest ; in the young all 

 the middle portion of the alidoraen between the broad white breast and the narrower 

 white groin is smoky brown ; in both there is a rudimentary daik median band, not 

 nearly so distinct as in T. kanchil. 



"In T. kanchil there are but throe white .stripes on the throat, the median line 

 being sometimes entirely distinct from tho two broad and long obli([uo lateral stripes, 

 sometimes coalescing with tliem in front ; the abdomen is pale rufous and white_ in 

 patches, the centre of the anterior portion and the sides of the posterior portion 

 being white, and the remainder rufous, but the proportion of the two colours varies; 

 tliere is, however, a well-marked dark median line along the anterior half, beginning 

 from the dark transverse band on the breast. 



" In both species the rump is rufous, and the tail brown above, white below and 

 at the tip. All the differences noticed, exc(!pt the number of white stripes on tho 

 throat, have already been pointed out by Blyth."
