  Molossops 
  mastivus, 
  sp. 
  n. 
  

  

  Allied 
  to 
  M. 
  cerasks, 
  but 
  larger. 
  

  

  Size 
  largest 
  of 
  the 
  genus. 
  Fur 
  very 
  close 
  and 
  velvety, 
  

   hairs 
  of 
  back 
  barely 
  over 
  2 
  mm. 
  in 
  length. 
  Structure 
  of 
  ears 
  

   and 
  distribution 
  of 
  fur 
  as 
  in 
  M. 
  cerastes. 
  General 
  colour 
  

   above 
  dark 
  chocolate-brown, 
  rather 
  paler 
  below. 
  

  

  Skull 
  like 
  that 
  of 
  M. 
  cerastes, 
  but 
  decidedly 
  larger 
  ; 
  ridges 
  

   and 
  crests 
  much 
  more 
  developed, 
  the 
  " 
  helmet 
  " 
  formed 
  by 
  

   the 
  junction 
  of 
  the 
  sagittal 
  and 
  lambdoid 
  crests 
  very 
  promi- 
  

   nent. 
  Muzzle 
  rather 
  narrower 
  in 
  proportion 
  to 
  the 
  length 
  of 
  

   the 
  skull, 
  and 
  not 
  so 
  markedly 
  flattened. 
  Brain-case 
  also 
  

   less 
  flattened 
  above. 
  Anteorbital 
  ridges 
  very 
  heavy. 
  Rami 
  

   of 
  lower 
  jaw 
  very 
  short 
  and 
  thick, 
  their 
  lower 
  profile 
  convex 
  

   from 
  end 
  to 
  end.
