Ha b. Lam-ra, Trang, Northern Malay Peninsula. 



Type. Old female. Original number 3478. Selangor 

 Museum number 1223/10. Obtained 1st February, 1910, by 

 Museum collector. 



The chief feature about this Arctonyx is its enormous size, 

 as the specimen looks like a small bear, and, though a female, 

 far exceeds any example, male or female, of A. collaris in the 

 Museum collection ; and A. collaris, in turn, is decidedly 

 larger than the Chinese species A. leucolcemus and A. ob- 

 scurus and the Assamese A. taxoi'des. 



In describing an Arctonyx from this region, however, 

 mention has to be made of Hubrecht's " Trichomanis hoeveni"* 

 from Sumatra, at first supposed to be, and described as, an 

 Edentate, but afterwards said f to be an Arctonyx. The type 

 was lost, and the description does not apply to any known 

 animal. 



Among other things it was said to be of the " size of a 

 very large cat," and Arctonyx dictator is many times larger 

 than any possible house-cat. In colour it was " grey with a 

 black band along the middle of the back " — no such coloration 

 is as yet known in Arctonyx. 



If an A rctonyx occurs in " the mountainous districts that 

 separate the Residencies of Palembang and Bencoolen," and 

 its characters are in any way compatible with those of 

 Hubrecht's animal, after elimination of the imaginary Eden- 

 tate attributes, the name hoeveni may have to be used for it. 

 But this is certainly not the case with Arctonyx dictator, 

 which is too large, and is quite unlike in colour.
