18 NILS GYLDENSTOLPE, THE SWEDISH ZOOLOGICAL EXPEDITIONS TO SIAM. 



Skull measurements : 



Total length = 20,5 mm; length of mandible from condylus to front of canine = 

 14,2 ; length of upper toothrow = 7,i; length of lower toothrow = 8,2 mm. 



Kerivoula hardwickii. Horsf. 



§ Hue Muang, Northwestern Siarn, i h 1914. — Forearm = 33.0 mm.; Ear = 14 mm.; Tail = 45,3 

 mm. Caudal vertebrates = 6. 



Even this specimen was caught in a wild banana tree growing in a dense ever- 

 green jungle near the bank of a small creek called Hue Muang, the sources of which are 

 situated on Doi Vieng Par, one of the highest and wildest mountains of Northwestern 

 Siarn. 



The dimensions of my specimen, though a female, are slightly larger than those 

 recorded for true Kerivoula hardwickii, Horsf. Especially the ears seems to be longer 

 and when laid forward reach some distance beyond the nose. 



The cranial dimensions, however, are almost exactly the same as given by Thomas 

 for typical Kerivoula hardwickii as seen by the measures given below. (Measure- 

 ments in brackets are those recorded by Thomas.) 



Total length of skull 15,5 mm. 



Basilar length 11,8 » (11—12 mm.) 



Condylo incisive length 13,7 (13,2—14 » ) 



Mastoid breadth 8,0 



Zygomatie width 9,0 (9,0—9,5 » ) 



Width of brain case 7,8 (7,8—8,2 » ) 



Breadth across palate at front end of last molar . 5,2 (5,0 — 5,8 » ) 



Upper toothrow (canine to last molar) 5,8 (5,5 — 6,0 



Lower toothrow (canine to last molar) 6,2 » 



Tupaia belangeri. Wagn. 



<£ Koli Lak Paa, near the boundary between Siain and Tenasserim, 7 /is 1914. — Nose to 

 vent = 165 mm.; tail = 175 mm.; hindfoot = 41 mm. — <£ Koh Lak, Siamese Malaya 27 /n 1914. — Nose 

 to vent = 176 mm.; tail = 158 mm.; hindfoot = 41 mm. 



Both these specimens are typical Tupaia belangeri as described by Wagner on a 

 specimen from the neighbourhood of Rangoon. This species extends as far down the 

 Malay Peninsula as to the Isthmus of Kra where it meets Tupaia lacernata wilkinsoni 

 Rob. & Kloss which belongs to a group which is almost intermediate in colour between 

 Tupaia belangeri Wagn. and Tupaia glis ferruginea Raffl. from the southern third of 

 the Malay Peninsula. Tupaia belangeri seems to be quite as common on the eastern 

 side of the Peninsula as on the western.
