One specimeii, Koh Lak, Siamese Malaya, January 1915. 

 Two specimens, Ban Sakerat, Easteru Siarn, January 1912. 



Siamese name: ngu liao talan. 



One of the specimens collected at Sakerat is very large as seen by the mea- 

 surements given below, although the tail, being in this species very long, to its 

 greatest part is löst. The specimen is larger than the largest specimen recorded in 

 the Catalogue Brit. Mus. (I 1 /* ni.). Apparently the specimen when alive measured 

 more than two metres in length. In both the Sakerat specimens the scales are 

 arranged in 15 rows, but only on the anterior parts of the body; already widely in 

 front of the middle part of the body the rows of scales are fewer; on the posterior 

 part of the body they are only 11. 



Measurements of specimens from Sakerat: 



Total length = 1620 mm. (tail broken) & 1530 mm. (tip of tail broken). 



Length of tail = 320 mm. & 570 mm. 



Ventrals = 320 & 171.
