A single female, with very worn teeth, from Ok Yam, Franco- 

 Siamese Boundary-. 



This race is differentiated from that of the Malay Peninsula 

 by the absence of any bladkish nape-stripe ; otherwise the colora- 

 tion of the two is similar. The bony orbit appears to be a trifle 

 lai'ger;

This form was first erected by Gray (P. Z. S. 1861, p. 138) 

 iipon material consisting of seven specimens from Cambodia, 

 collected by Mouhot. In the cotirsfe of his description, he states 

 tliat "a specimen of the species has been in the Museutn as above 

 named for many years : it is said to have come from Singapore ; 

 but that probably Avas only the port of transit." This remark 

 can hardly be regarded as the citation of the type, so that the 

 name affinis must be confined to the Indo-Chinese form, for it 

 was further a nomen nildMni initil rendered available for use 

 through being applied with description to the Cambodian 

 animals specified therein. 



In 1903, Ml- Bonhote (Ann. & Mag. Nat. Hist.) took the vieAv 

 that affinis should be referred to the Malayan aliimal with the 

 specimen of dubious provenance for type, and redescribed a 

 Cochin-Chinese example under the naine T. k. pierrei. Latei-, 

 howevef (P. Z. S. 1907, J). 11), he found reason to change his 

 opinion, and accepted the name of affinis fot- the Indo-Chinese 

 form . 



Even the strict systematist, Who holds that the first locality 

 cited is that of the type-specimen, must, I think, accept this 

 view, for the title of the paper in which this species is dealt 

 with is "List of Mammals, etCi, collected in Cambodia" and, 

 unless otherwise specially excepted in the text, this locality has 

 priority. 



In the Brit. Mus. Cat; Ungulates, vol. iv., Lydekker appears 

 to have overlooked the aboVe factSi The unfoi-tunate term 

 " Lowef Siam," applied by several describers of species to the 

 northern half of the Malay Peninsula, i. e., Peninsular Siam, has 

 been the cause of mueh confusion to othei-s who do not use their
