Type.— Old male. B.M. No. 8. 1. 25. 21. Original number 325. 

 Collected 13th June, 1906. 



The specimen which I take as a characteristic example of the 

 peninsular macrourus agrees closely in its skull-measurements with the 

 one from Trong referred to by Miller in his descrij^tion of A. 

 iiygomaiiciis. Of its skull, the upper length is 100 mm., the height of 

 the muzzle 21, of the crown 29, and the length of the upper tooth- 

 series is 18 mm. It was obtained at Jalor by Messrs. Robinson aud 

 Annandale. 



This animal is clearly a small insular repi'esentative oiA. macrourus, 

 and does not show the peculiarities that distinguish the Aor Island 

 form.

 Topotypes. 



These specimens quite agree with Mr. Miller's description, both iu 

 the peculiar character of the zygomata and in the dark colour of their 

 sides and bellies. 



Among the Eastern Atheruri iu the British Museum I find 

 an example of this species which was purchased in 1881 from a dealer, 

 and was labelled in Japanese writing " Fasciculated Porcupine — 

 natiA'e name Tea ]jhu Jcoku — India."

"Very common. Caught in fall-traps baited with jackfruit." —

These specimens differ from Mr. Miller's descnption by having 

 their bellies more or less washed with fulvous, but appear to agree iu 

 all other respects. 



They also entirely agree in colour with the type of Gray's Tragulus 

 do ahy CUIUS, a s|x;cies whose exact locality has, to my knowledge, never 

 l.)een definitely determined ; but their skulls are so far smaller 

 that they cannot be referred to it. 



Probably T. stanleijaaus will prove to occur on the mainland and 

 to Ix^r much the same relation to T. riifulus that Atherurus macrourue 

 does to A. tionie.
