24 NILS GYLDENSTOLPE, THE SVVEDISH ZOOLOGICAL EXPEDITIONS TO SIAM. 



The wild dögs generally assemble in packs and during the rainy season they are 

 chasing the deer down in the rivers where they kill them. This according to some na- 

 bives who I questioned abont the behavior of the wild dögs.

The race inhabiting Tenasserim north to the Shan States and south to the Malay 

 Peninsula has quite recently been separated from the true Viverra zibetha Linn. on account 

 of the total abscence of a yellowish tinge in the ground colour of that species. In Viverra 

 zibetha Linn. all the hairs are tipped with buff while in Viverra zibetha pruinosa they are 

 tipped with white. This point of charaeteristic agrees well with the specimens in m}* 

 collection which I without hesitation have referred to the above-mentioned form. 



This Civet was apparently very common in the evergreen jungles on the boundary 

 between Siarn and Tenasserim on abont Lat. N. 12°, and like the other Civets it is easilv 

 trapped. In the Northern parts of the country it, however, seems to be rather rare and 

 no specimens were obtained. Its tracks were, however, seen at a few occasions. It has a 

 cnrious habit of letting its droppings on the fallen trees in the jungles. All the specimens 

 obtained were canght in traps where the bait consisted of flesh sometimes of its own 

 comrades.
