width of palate between last molars = 14,5; front of canine 

 to back of last molar == 25,4; length of iipper molar series 

 = 22,0; length of lower molar series = 24,o mm. 



2. Macaca irus Cuv. - 1 ¥ 'V^ 1915; 1 ? ^Vi 1915. 

 In one] of these speeimens the tail measnres 490 mm., 



and in both speeimens the annulations of the hairs are well- 

 marked all över the body and limbs. 



This is a common species all över the Peninsula. 



Skull measurements: Greatest length: 102,o & 96, 0; 

 condylobasal length =76,o & 68,0; basieranial length = 67,o 

 & 58,5; occipitonasal length = 84, o & 78,6; zygomatic width 

 = 65,0 & 54,0; greatest breadth of brain case = 52,5 &49,o; 

 leastpostorbital width == 39,i & 39,o; least interorbital width 

 = 4,0 & 4,0; length of i)alate to henselion = 39,ö & 34, o ; 

 width of palate between last molars = 15, o & 13,4; front of 

 canine to back of last molars --= 32,3 & 26,5; length of upper 

 molar series =26,5 & 21,2; length of lower molar series = 

 31,0 & 23,0 mm. respectively. 



3. Tiipjiia i,-lis fernigiiiea Raefl. — 1 ? Vr^l915. Nose 

 to vent= 173 mm.; hindfoot = 40 mm. 



Quite a typical specimen of the common Tupaia glL^ 

 ferruginea Raffles, though the hindfoot is unusually small 

 measuring only 40 mm. against abont 45 mm. in typical 

 speeimens. 



Skull measurements: Greatest length = 46,5; condylo- 

 basal length =44,6; basicranial length = 41,3; zygomatic 

 width = 23, 1 ; greatest breadth of brain case = 19,i ; least inter- 

 orbital width = 13,1 ; least postorbital width = 16,7 ; greatest 

 length of nasals mesially = 14,8; breadth of combined nasals 

 at anterior extremity = 2,6 ; palatal length mesially = 25,o 

 mm. 



4. Lutra ciiierea Illiger. — 1 J^ 7^ 1915. Nose to vent 

 = 490 mm.; Tail = 260 mm. 



This small clawless Otter is the most common species of 

 Otter met with in the whole Peninsula. It may at once be 

 distinguished from the other members of the tribe occurring 

 in the Malay region viz. Lutra sumatrana Gray. and Lutra
