the right bank of the Meh Koke river. Chieng Hai is surrounded by great swamps, 

 the haunt of rbinoceroses and other big game, and I found several interesting snakes 

 in that neighbourhood. 



Vieng Pa Pao lies on the main road from Chieng Hai to Chieng Mai and all 

 around there are rice-fields and cultivated country. 



Pong Pa Oh is a poor little village consisting of a fevv huts only, found high 

 up in the mountains in about 19° 20' N. latitude, 90° 40 r E. longitude. 



In November 1914 I went down b} 7 rail to the Siamese Malaya. I took my 

 headquarter in Koh LaJc, a nice place on the coast of the Gulf of Siarn only a few 

 miles from the Tenasserim boundary. Koh Lak and its surroundings were verv good 

 for collecting purposes and the fauna had quite a different and more Malayan character. 

 I also went up to the mountains dividing Siarn and Tenasserim and had my camp in 

 the thick evergreen jungles, through which the small creeks Hue Sai and Hat Sanuk 

 are running. 



Bång Tapan is a small place further south from Koh Lak. 



In conclusion I want to express publicly my very best thanks to Mr. V. Wra- 

 geen and Doctor Malcolm Smith, who both with great generosity presented valu- 

 able collections of snakes to the Natural History Museum in Stockholm. 



In the following notes the species in these collections are also recorded. 



I am also very much indebted to Doctor L. G. Andersson who examined 

 the species which were brought home from my first expedition and permitted me to 

 use his manuscript notes on them. 



1. Typhlops braminus Schneid. 



Two specimens from the ueiglibourhood of Bangkok (V. Wirgeen coll.). 

 Siamese name: ngn din. 



This species seems to be fairly common in Siarn, but on account of its habits 

 always burrowing in the earth it is rather seldom met with. It inhabits Southern 

 Asia and the islands of the Indian Archipelago and extends to Southern Africa, 

 Madagascar and Mexico. 



All burrowing snakes are considered as very poisonous by the Siamese and very 

 much dreaded. Of course, this is quite wrong, and it is quite an harmless creature. 



The colour of one of my specimens is bluish gray; snout, anal region and end 

 of tail yellowish white. 



Total length = 154 & 155 mm. respectively. 



Scales in 20 rows. 



I have also seen specimens from Chieng Mai and Raheng, both places in North- 

 ern Siarn.
