 and 22-31 in females; 9-12 annuli on the tail in males and 6-8 in 

 females; ventrals 180-187 in males and 193-208 in females; anterior

 as stated by Boulenger (p. 420). 



3. MICRURUS CORALLINUS DUMERILU (Jan)

Very recently I revised *^ the nomenclatorial aspect of the mooted 

 question regarding the names M. lemniscatus and M. ibiboboca. I 

 am able now to say that the latter is a strict synonym of the former. 



If we compare Boulenger's description of both his M. lemniscatus 

 {E. lemniscatus) and M. ibiboboca (E. marcgravii) we find that the 

 only point of distinction between these species consists in the number 

 of ventrals and in the corresponding number of sets of black annuli- 

 Boulenger's figures are as follows:
