ON A THIRD COLLECTION OF SIAMESE MAMMALS. 



BV C. BODKN Kloss, I', z. s. 



The specimens on wliicli the present paper is based were sent 

 me b}' H. 11. H. Prince Abhakara at Cluunporn and Messrs Aagaard, 

 Eisenhofer, Eiwes, Gairdner, Irwin, Wedderburn and Yates; also by 

 Messrs Williamson and Smith who as usual are re.«ponsible, through 

 their collectors, for the largest number. 



Putani, from which some of the material comes, though politi- 

 cally part of Siam, both geographically and zoologically belongs to the 

 Malayan sub-region and is lacking in true Indo-Chinese species, while 

 many species occur in it which iiave not been found north of tlie 

 Isthmus of Kra ; these, which are purely Malayan, I iiave marked with 

 an asterisk. 



1 am much indebted to the above members of the Society for 

 the opportunitj' of examining their specimens. 



1. Presbytis obscura flavicauda. 



ryijathixjhtricauda Elliot, Proc. U. 8. Nat. Mus., 38, p. 3.52 (1910) 

 Preshi/tis oA.stw/'k Jha-icauda Kloss, antea, p. 5. 



1 cJ ad. Bang Nara, Patani, I'eninsular Siam. 9 July 1916 

 [No. 2476]. 



1 d imm., 1 $ ad. Pak Nam Chumporn, S. W. Siam.' 11 July 

 1917 [Nos. 2565-6]. 



Ail obtained by Messrs Williamson and Smitli's collectors. 



The Patani specimen lacks the buffj' tinge on the cap of the 

 Leaf-Monkeys from Tung Sawng, Niikon Sri Tamarat, previously des- 

 cribed, and its hind limbs and tail are a trifle paler. 



One of the Chumporn animals agrees with it but the other has 

 the hinderparts a trifle paler still: it is however unquestionably refer- 

 able to the Ti-ang race and not to P. o. smitki of Patiyu (antea p. 5). 

 For measurements see p. 289. 



^ I have foUowwl Dr. Malcolm Sinilli (antea, p. 49) in nsing: the term 

 S. W. Siam for tlie coiiiilry hetwoen the retelialnni River and the Istlimiis of 

 Kra: this area funned the smitlierii ami nortiieni extieme.s respeetively of 

 Western and I'eninstilar Siani as defined in my note on zoogecgrapliieal divi- 

 sions ( vol. 1, ji. 'iM and Map ) wliere they were given too great a range of 

 latitude.
