 Me-tan-jà, Kakhien Hills. 



A variety without the vertebral line , which is replaced by 

 a series of distant small black spots; ventrals spots not extending 

 to the dorsal scales; tail annulate. 



Azemiops, g. n. 



Maxillary short , erect, bearing a single large perforated fang ; 

 palatine and pterygoid teeth numerous , small. Head distinct 

 from neck; nostril pierced in a single nasal; eye small, with 

 vertical pupil ; two prae- and two postoculars ; loreal present. 

 Body and tail moderate, cylindrical ; scales smooth; anal single; 

 subcaudals double. 



The nearest ally of this genus appears to be Dinodipsas 

 Peters (SB. Ak. Beri. 1882, p. 893, pi. XV.), from Puerto Ca- 

 bello, which is likewise provided with a loreal shield, but which 

 differs in Leptognathoid external characters , undivided sub- 

 caudals, keeled scales, etc. The discovery of that genus excited 

 great interest among herpetologists as the group to which it 

 belongs ( ( Giftnattern ', Atraclaspididae and Causidae) was be- 

 lieved to be restricted to Africa, where it is largely represented. 

 I may well say that Azemiops is the most interesting Ophio- 

 logical discovery made since that of Dinodipsas; and it affords 

 me great pleasure to connect with it the name of the courageous 

 and highly successful explorer to whom science is indebted for 

 this and so many other additions.
