In Siarn three different races of this Mårten may flien occur: 1) Mattes flavigula 

 flavigula Bodd. inhabiting the most northern parts of the country, 2) Hartes flavigula 

 peuinsularis, Bonh. from Peninsular Siani and 3) Maries flavigula indochinensis, Kloss. 

 from South-eastern Siarn. 



Lutra nair. Cuv. 



Some specimens of Otters were observed in the Meh Lua River some distance nortli 

 of the town of Chieng Hai in Upper Siarn. I only once had the opportunity of firing a 

 shot at an otter, but it only got wounded and was löst among the reeds. 



At Chieng Hai Dr. Briggs presented me a dried skin without skull of an otter hav- 

 ing been shot at the neighbourhood of the town. This is probably a specimen of Lutra 

 nair Cuv. though the exact determination is of course impossible. The specimen, how- 

 ever, fairly well agrees with the description of L. nair. The lower parts of the body are 

 distincly whitish and the fur on the chin and throat are white throughout. Whiskers 

 yellowish white. 



Thos aureus crusemanni. Matschie. 



The Jackal inhabiting Siarn has been separated by Matschie under the name of 

 Thos aureus crusemanni . This race was founded on specimens collected at Nong Bua 

 in Eastern Siarn. It may be distinguished by having two white bars running across the 

 breast which is greyish brown; about two thirds of the upper part of the tail is pure black 

 and the white colour on the upper lip is strongly marked off from the sides of the head. 



During my whole journey in Siarn I only once met with a Jackal. When marching 

 down to the coast after having spent some weeks among the mountain forests at Hat 

 Sanuk in the Siamese Malaya I caught a glimpse of a Jackal which leisurely came trotting 

 on the path I was following. Before I could fire a shot after it, it disappeared into the 

 jungle where it was löst for ever. 



Doctor Malcolm Smith showed me a skin of a Jackal which was said to ha ve been 

 obtained somewhere in Muang Pran, thus the same district where I observed this fine 

 animal. Unfortunately I did not take any special records about that skin and I am there- 

 fore unable to state if it belonged to the form described by Matschie or not. 



From the Malay Peninsula it has nevertless not been recorded before. 



Cuon rutilans. S. Mull. 



Wild Dögs probably belonging to this species, occur here and there at suitable lo- 

 calities över the whole country but as they are very shy and keep to the densest jungles 

 they are very seldom met with. 



I, never myself saw any but my Dyak collector met with one during one of his ex- 

 cursions in the jungles at the neighbourhood of Koh Lak. Though he fired 4 shots after 

 it he did not get it on the spöt.
