of its mouth, and the fossuljE in its nasal [dates, indicate that 

 t b elongs to the genus Elaps. Perhaps it might form the 



type of a new genus of venomous serpents ; but unless otlier 

 species resembling it be hereafter found, it is better to avoid 

 the multiplication of genera, — the rage for which has too often 

 greatly retarded the study of Natural History. I have, therefore, 

 considered it as an Elaps, and beg leave to designate it 



Elaps Jamesoni. 

 The only specimen which I have seen, and which is in my

 Each scale on the posterior part of the body, and also on the 

 whole tail, is edged with deep black; and on the latter they 

 are, moreover, tipt with the same colour, giving a very ele-

 under parts of the body is yellowish- white, but the abdominal
