  crepancy 
  in 
  the 
  length 
  of 
  these 
  hairs 
  far 
  greater 
  than 
  in 
  those 
  of 
  the 
  

   dorsal 
  surface, 
  anteriormost 
  a 
  little 
  less 
  than 
  half 
  as 
  long 
  as 
  posterior- 
  

   most, 
  latter 
  a 
  little 
  shorter 
  than 
  the 
  longest 
  dorsal 
  hairs. 
  

  

  Mouth 
  parts 
  normal, 
  pedipalps 
  short 
  and 
  stout, 
  both 
  second 
  and 
  third 
  

   segments 
  above 
  with 
  a 
  setif 
  orm 
  hair, 
  that 
  of 
  the 
  second 
  weakly 
  barbed 
  

   and 
  only 
  a 
  little 
  stouter 
  than 
  that 
  of 
  the 
  third, 
  which 
  is 
  smooth. 
  

  

  Legs 
  equal-sized, 
  rather 
  small 
  in 
  proportion 
  to 
  the 
  body. 
  Pos- 
  

   terior 
  common 
  coxa 
  differing 
  from 
  most 
  species 
  of 
  Gechobia 
  in 
  having 
  

   two 
  spurlike 
  hairs 
  on 
  its 
  anterior 
  and 
  only 
  two, 
  one, 
  or 
  even 
  none 
  

   on 
  its 
  posterior 
  margin 
  ; 
  usually 
  only 
  three 
  or 
  four 
  hairs, 
  instead 
  of 
  

   the 
  normal 
  five, 
  are 
  found 
  on 
  this 
  coxa 
  and 
  these 
  are 
  comparatively 
  

   small 
  and 
  weak. 
  The 
  basal 
  segments 
  of 
  the 
  legs 
  without 
  spurlike 
  

   hairs 
  ventrally; 
  but 
  the 
  second 
  segment 
  in 
  all 
  legs 
  with 
  a 
  rather 
  

   long, 
  slender, 
  and 
  weakly 
  barbed 
  hair 
  above.

  Remarks. 
  — 
  The 
  species 
  closely 
  resembles 
  Gechohia 
  simplex 
  Hirst, 
  

   1926, 
  described 
  from 
  Hemidactylus 
  leschenaulti., 
  Madras, 
  India, 
  in 
  

   the 
  shape 
  of 
  the 
  hairs 
  of 
  the 
  dorsal 
  surface 
  and 
  in 
  the 
  form 
  of 
  the 
  

   dorsal 
  scute. 
  It 
  differs 
  from 
  this 
  species 
  in 
  having 
  only 
  about 
  half 
  

   the 
  number 
  of 
  hairs 
  on 
  the 
  dorsal 
  scute, 
  these 
  being 
  also 
  more 
  similar 
  

   to 
  the 
  remaining 
  body 
  hairs 
  in 
  length 
  and 
  thickness 
  than 
  is 
  the 
  case 
  

   in 
  G. 
  simplex. 
  It 
  further 
  differs 
  in 
  there 
  being 
  very 
  little 
  difference 
  

   in 
  the 
  shape 
  of 
  the 
  dorsal 
  hairs 
  of 
  the 
  second 
  and 
  third 
  palpal 
  

   segments.

  Body 
  much 
  wider 
  than 
  long, 
  dorsal 
  surface 
  as 
  in 
  figure 
  4, 
  with 
  9 
  or 
  

   10 
  large, 
  wide 
  hairs 
  in 
  the 
  area 
  usually 
  occupied 
  by 
  the 
  dorsal 
  scute, 
  

   those 
  in 
  the 
  middle 
  of 
  the 
  body 
  much 
  smaller, 
  while 
  towards 
  the 
  pe- 
  

   riphery 
  posteriorly 
  and 
  laterally, 
  the 
  hairs 
  become 
  progressively 
  more 
  

   elongate 
  and 
  pointed. 
  A 
  single 
  pair 
  of 
  centrally 
  situated 
  hairs 
  much 
  

   longer 
  than 
  the 
  predominantly 
  short 
  hairs 
  by 
  which 
  they 
  are 
  sur- 
  

   rounded. 
  Dorsal 
  scute 
  not 
  defined. 
  

  

  Ventral 
  surface 
  as 
  in 
  figure 
  5, 
  a, 
  which 
  represents 
  a 
  section 
  in 
  the 
  

   middle 
  line 
  of 
  the 
  body 
  extending 
  from 
  its 
  anterior 
  to 
  its 
  posterior 
  

   margin; 
  the 
  transition 
  from 
  the 
  small 
  type 
  of 
  cylindrical 
  hair 
  to 
  

   scales 
  of 
  lanceolate 
  form, 
  sudden 
  and 
  without 
  intermediate 
  types 
  of 
  

   hair; 
  the 
  scales 
  toward 
  the 
  posterior 
  periphery 
  becoming 
  progres- 
  

   sively 
  more 
  elongate 
  and 
  narrow.
