an exact determination of the species. Neither in Northern, 

 nor in Central Siarn a single specimen was noticed. 



As a curiosity I want to remark that båts were very 

 rare över the whole country. Several times I examined caves 

 which had been inhabited by båts to judge from the large 

 quantities of their droppings, but except for a few individuals 

 not a single colony was found. This seems very curious as 

 båts are very numerous in Eastern Asia, and I think their 

 absence must be due to some disease having killed almost 

 every bat. 



8. Tupaia belangeri Wagn. — Tupaias were fairly 

 common över the whole of Siarn, but they were ne ver observed 

 in the real virgin forests. In the open dry forests, however, 

 specimens were seen now and then. 



These animals seem to live more on the ground than 

 up in the trees, but sometimes they were noticed climbing 

 in a squirrel-like manner on the fallen trees. As a rule they 

 were rather shy, and they took at once their refuge into a 

 hole in the trees as soon as they were disturbed. Two speci- 

 mens were of ten seen chasing each other with utmost rapi- 

 dity, then always uttering a sharp smacking sound. When 

 feeding they sit on their haunches, holding the food with 

 their forelimbs. I never observed them in, or near the native 

 huts as is stated by some authors. In their whole appear- 

 ance they very much resemble squirrels, and at a distance 

 it is very härd to make out whether it is a squirrel, or not, 

 but generally the tupaias seem to be less active. 



The race inhabiting Siarn is the same one which has been 

 found in Lower Burma and Tenasserim. It differs from its 

 nearest ally Tupaia ferruginea Raffles, which is a more 

 southern form inhabiting the Malay Peninsula, i. a. of being 

 of a yellowish brown colour, while the latter is of a deep 

 rusty brown colour. 



From Upper Burma and Karennee another allied species, 

 Tupaia chinensis Anders, has been described, thus it seems 

 that the distribution of Tupaia belangeri Wagn. is confined 

 only to a rather small area. 



In my Siamese collection there are specimens from Den 

 Chai in Northern and from Sakerat in the Eastern parts of 

 the country.
