I have the jaws of the largest specimen referred to and a complete skull 

 of a Jalpaiguri specimen, and the dentition shows fewer teeth in the man- 

 dibles than in niger, of which I have five skulls. In both species there are 

 three small grooved teeth in the maxillar behind the pair of fangs. In 

 iividus the palatine teeth are 9, x^terygoid 7 to 9 and the mandibular 12. 

 In niger the palatine are 9 to 13, pterygoid 8 to 11, and mandibular 15 

 to 18. 



I could gain no information in Assam about the poisonous effects of the 

 bite of niger, but was more fortunate in obtaining information about Iividus. 

 A planter near Tezpur had a cooly woman bitten by one, and she died 

 some 12 to 18 hours later. The specimen was killed and kept, and sub- 

 mitted to me for identification. It measured 3 feet 2 inches, and was 

 much the largest I have seen. No medical details of this case were kept 

 unfortunately . 



BUNGAKUS LIVIDUS.
