  the 
  plate, 
  and 
  (lie 
  latter, 
  again, 
  is 
  opposite 
  the 
  extreme 
  front 
  

   edge 
  of 
  m 
  1 
  ). 
  Front 
  edge 
  of 
  zygomatic 
  plate 
  slanted, 
  little 
  

   curved, 
  not 
  subangularly 
  projected 
  forward. 
  Palatal 
  foramina 
  

   shorter, 
  barely 
  equalling 
  the 
  length 
  of 
  the 
  molar 
  series. 
  

  

  Molars 
  not 
  so 
  simple 
  and 
  Epimys-Wke 
  as 
  in 
  Hybomys, 
  but 
  

   more 
  tending 
  to 
  the 
  character 
  of 
  those 
  of 
  Mylomys 
  as 
  com- 
  

   pared 
  to 
  Pelomys 
  *, 
  although 
  not 
  so 
  extreme. 
  

  

  The 
  middle 
  cusp 
  of 
  each 
  lamina 
  is, 
  as 
  in 
  Mylomys, 
  highly 
  

   developed, 
  beak-like, 
  directed 
  backwards, 
  the 
  lamina? 
  are 
  

   similarly 
  curved 
  round, 
  and 
  complicated 
  by 
  the 
  development 
  

   of 
  connecting-ridges 
  between 
  the 
  laminae, 
  notably 
  between 
  

   the 
  first 
  and 
  second 
  laminae 
  of 
  m\ 
  

  

  Type. 
  Typomys 
  trivirgatus 
  {Mus 
  trivirgatus, 
  Temm.). 
  

  

  The 
  character 
  of 
  the 
  molars 
  of 
  this 
  animal 
  is 
  one 
  common 
  

   to 
  several 
  African 
  genera 
  — 
  e. 
  g., 
  Mylomys, 
  (Enomys, 
  and 
  

   DesmomyS) 
  — 
  but 
  as 
  to 
  whether 
  it 
  is 
  an 
  independent 
  develop- 
  

   ment 
  in 
  each 
  case 
  or 
  shows 
  any 
  community 
  of

   not 
  at

  prepared

  express 
  an 
  opinion. 
  Hybomys, 
  

   otherwise 
  not 
  widely 
  different 
  from 
  Typomys, 
  has 
  quite 
  

   normally 
  constructed 
  molars. 
  

  

  Six 
  specimens 
  of 
  Typomys 
  trivirgatus 
  were 
  obtained 
  by 
  

   Mr. 
  Bunting 
  in 
  Liberia.
