6 NILS GYLDENSTOLPE, THE SWEDISH ZOOLOGICAL EXPEDITIONS TO SIAM. 1. SNAKES. 



2. Typhlops diardi Schleg. 



Two specimens, Chieng Hai, Upper Siam, July 1914. 



This species which is distributed in Bengal, Sikhim, Khasi Hills, Assam, Burma 

 and Cochin China, has not as far as I am aware been recorded from Siam. 



Mv specimens agree perfectly well with the description of the species with the 

 exception that the rostral hardly extends to between the eyes. 



Total length = 400 & 345 mm. respectively. 



3. Python reticulatus Schneid. 



One specime», Bangkok (M. Smith coll.). 

 One specimen, Bangkok (V. WlfiGEEN coll.l. 



Siamese name: ngu leaum. 



The python is fairly common över the whole of Siam, not even uncommon in 

 Bangkok itself, though real large specimens are seldom met with. 



Total length of my specimens: 908 mm. & 1460 mm. 



Length of tail = 125 mm. & 230 mm. respectively. 



Ventrals = 313 & 320.

The gall-bladder and some other parts of the intestine are highly valued by 

 the Siamese who make some sort of. medicine out of it.

The natives say that this snake bites with both ends and it is mueh dreaded 

 by the people, but according to l):r Smith it is »a most inoffensive creature». 



All the specimens collected are vcry dark (almost black), and there is only one 

 which is of a brownish oolour. 



»The Larger of the two specimens collected in Hangkok 1911 is uniform dark 

 above; the .smaller has the usual light crossbands although even in this latter rather 

 dark.» L. (I. Andersson. 



Specimens in alcohol ahvays loose the reddish colour of the tail.
