  Very 
  recently 
  I 
  revised 
  13 
  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:
