  on 
  a 
  new 
  Bat 
  from 
  the 
  Gambia. 
  

  

  pair, 
  quite 
  different 
  from 
  those 
  of 
  any 
  other 
  member 
  of 
  the 
  

   genus. 
  The 
  inner 
  one 
  with 
  a 
  large 
  secondary 
  cusp 
  about 
  

   halfway 
  up 
  its 
  posterior 
  edge, 
  and 
  the 
  hinder 
  edge 
  of 
  

   the 
  main 
  cusp, 
  above 
  the 
  secondary 
  one, 
  markedly 
  sinuous, 
  

   as 
  though 
  the 
  tooth 
  were 
  occasionally 
  trifid 
  (fig. 
  b) 
  . 
  Outer 
  

   incisor 
  well 
  developed, 
  triangular 
  in 
  section 
  at 
  the 
  base 
  (see 
  

   fig. 
  c), 
  its 
  angles 
  each 
  with 
  a 
  cusp^ 
  the 
  antero-internal 
  

   bearing 
  the 
  long 
  main 
  cusp, 
  three 
  fourths 
  the 
  height 
  

   of 
  the 
  inner 
  incisor 
  ; 
  cusp 
  on 
  the 
  postero-internal 
  angle 
  

   about 
  half 
  the 
  height 
  of 
  the 
  secondary 
  cusp 
  of 
  the 
  inner 
  

   incisor; 
  cusp 
  <>n 
  t 
  he 
  external 
  angle 
  minute, 
  but 
  quite 
  

   distinct 
  (fig. 
  d) 
  ; 
  postero-external 
  side 
  of 
  the 
  tooth 
  close 
  

   to 
  the 
  base 
  of 
  the 
  canine 
  (fig. 
  c) 
  . 
  Xo 
  trace 
  of 
  a 
  minute 
  

   anterior 
  premolar; 
  large 
  premolar 
  pressed 
  closely 
  against 
  

   the 
  back 
  of 
  the 
  canine 
  and 
  leaving 
  no 
  room 
  for 
  another 
  tooth 
  

   between. 
  

  

  Lower 
  incisors 
  trifid, 
  overlapping, 
  placed 
  at 
  right 
  angles 
  to 
  

   the 
  direction 
  of 
  the 
  jaws. 
  Second 
  lower 
  premolar 
  two 
  thirds 
  the 
  

   height 
  of 
  the 
  canine, 
  and 
  first 
  premolar 
  two 
  thirds 
  its 
  height. 
  

  

  Dimensions 
  of 
  the 
  type 
  (an 
  adult 
  male 
  in 
  spirit) 
  : 
  — 
  Head 
  

   and 
  body 
  50 
  millim. 
  ; 
  tail 
  39; 
  forearm 
  36 
  (=1*4 
  inch); 
  

   head 
  16*5; 
  muzzle 
  to 
  eye 
  7*0; 
  car, 
  above 
  crown 
  9"0, 
  from 
  

   base 
  of 
  external 
  margin 
  130; 
  thumb, 
  including 
  claw,

   lower 
  leg 
  13'6. 
  

  

  The 
  type 
  specimen 
  of 
  this 
  most 
  interesting 
  bat 
  was 
  obtained 
  

   by 
  my 
  friend 
  Dr. 
  Percy 
  Kendall 
  at 
  Bathurst, 
  on 
  the 
  River 
  

   Gambia, 
  and 
  I 
  have 
  much 
  pleasure 
  in 
  connecting 
  his 
  name 
  

   with 
  it. 
  

  

  Vesperuffo 
  Bendalli 
  presents 
  a 
  combination 
  of 
  characters 
  

   which 
  prevents 
  it 
  falling 
  into 
  any 
  one 
  of 
  the 
  subgenera 
  of 
  

   Vesperugo 
  as 
  recognized 
  and 
  defined 
  by 
  Dr. 
  Dobson 
  (Cat. 
  

   Chir. 
  B. 
  M. 
  p. 
  184,. 
  But 
  I 
  am 
  far 
  from 
  regarding 
  it 
  as 
  

   representing 
  a 
  new 
  subgenus, 
  and 
  only 
  consider 
  it 
  as 
  showing 
  

   that 
  Hesperoptenus, 
  Peters, 
  in 
  which 
  a 
  penis-bone 
  is 
  present 
  

   and 
  the 
  outer 
  incisors 
  are 
  minute, 
  should 
  be 
  amalgamated 
  

   with 
  Vesperus, 
  in 
  which 
  there 
  is 
  no 
  penis-bone 
  and 
  the 
  outer 
  

   incisors 
  are 
  well 
  developed. 
  The 
  swollen 
  and 
  probably 
  ad- 
  

   hesive 
  hinder 
  pads 
  of 
  this 
  species 
  give 
  it 
  a 
  second 
  point 
  of 
  

   resemblance 
  to 
  V. 
  ("Hesperoptenus") 
  Blanfordt, 
  Dobs. 
  ; 
  but, 
  

   as 
  Dr. 
  Dobson 
  has 
  shown, 
  this 
  character 
  is 
  not 
  one 
  on 
  which 
  

   generic 
  or 
  subgeneric 
  division 
  can 
  be 
  based.
