Remarks. — The above measurements show the much greater 

 size of tlie eastern animal as compared with the western indi- 

 viduals, while the colour of the lattei', given by Thomas as " clear 

 slaty grey," is also very different from the brownish tone of the 

 other. 



The type of Epimys herdmorei was described as being of about 

 a foot in length, of which the tail was not quite half; hind foot 

 1^ inches. Fur shortish, even, coarse and hispid, but not spinous, 

 of one quality only. Incisors white. Tail i-ather n)ore copiously 

 clad than usual with short hairs. The upper side, originally given 

 as grizzled-gi-ey, unmixed with rufous, was later stated by Blyth 

 (ojo. cit. xxxii. p. 343) to be dull brown, which is in close agree- 

 ment with the colour of the present animal. 



The species is in no way related to E . ferreocanus Miller, of 

 Peninsular Sia,m. 



41. ACANTHION KLOSSI ThoS. * 



A single porcupine of the hengalensis type was obtained on the 

 mainland at Klong Yai. 



It is remarkable how little information we have concei'uing 

 Hystrix hengalensis. There is Blyth "s original description * 

 founded, I am able to state (thanks to authorities of the 

 Indian Museum, Calcutta, who have lent me the type skull 

 for examination), on a half-grown individual with incomplete 

 dentition, supposed to come from the Sunderbunds. Thei'e is 

 Jerdon, in the ' Mammals of India," who borrowed from Bl3'th, 

 and there is Anderson, who, in his ' Zoological Researches,' when 

 treating of H. yunnanensis^ gives (passim) a few fresh details, 

 while Blanford, the latest author to deal with the species, had 

 no material for examination when writing for the ' Fauna of 

 British India,' and simply repeated Blyth 's original description. 

 Beyond this unsatisfactory literatiu-e no other details of topo- 

 types seem available, and I am forced to supplement it by 

 measurements of a skull from the Karen Hills given by Thomas 

 in his paper on the Mammalia collected by Signer Fea in 

 Burma and Tenasserim f. 



The present example, while generally agreeing externally with 

 descriptions of Acanthion hengalensis (Blyth), differs in the fol- 

 lowing respects : — The longest bristles of the crest are only 4 to 

 5 inches long, but are tipped with white for more than half their 

 length ; the white demi-collar is ill-defined on the middle of the 

 throat ; the quills are white with a dark band at their centres, 

 rather than white and black with a more or less defined white 

 tip, and the few long flexible quills are white throughout, lacking 

 any dark middle band. Blyth's description, however, is hardly
