NOTES ON SNAKES COLLECTED JN OPPEIi ASSAM. 835 



I find referring to many specimens 1 have examined from Darjeeling 

 and Burma that this appears constant. 



The dentition in my two skulls does not appear to agree quite with 

 Boulenger's figure of D.mycterizans (Catalogue Vol. Ill, p. 177). 



Maxilla.— 6 or 7 progressively lengihening teeth from before 

 backwards, then a short interspace followed by o or 4 minute teeth, 

 then a second gap followed by two large, subequal, grooved, fang-like 

 teeth. (In Boulenger's figure two suddenly enlarged fang-like teeth 

 succeed six small subequal ones in the front of the jaw.) Palato- 

 pterygoid 10 + 20 or 21, small, subequal, slightly reducing posterior- 

 ly. Mandibular .5 or 6 rapidly increasing posteriorly ; then a short 

 gap followed by, from 12 to 14, small subequal teeth. 



Sub-family — Elapinab. 



Bungarus fasciatus (Schneider). 



I acquired 22 examples. Two were from near Doom Dooma, one 

 from near Tinsukia, one from North Lakhimpur at foot of Duffla 

 Hills, and the rest from just around Dibrugarh. Of 11 sexed 5 were 

 (J,6 9.
