  process 
  of 
  the 
  premaxillary 
  triangular 
  ; 
  no 
  sheath 
  of 
  scales 
  along 
  base 
  

   of 
  dorsal 
  or 
  of 
  anal 
  fins 
  seen 
  on 
  the 
  types, 
  but 
  these 
  are 
  easily 
  lost 
  in- 
  

   preservation, 
  and 
  since 
  the 
  majority 
  of 
  "3/. 
  vagrann''' 
  in 
  the 
  collections 
  

   are 
  lacking 
  the 
  scales, 
  this 
  character 
  is 
  of 
  value 
  only 
  on 
  perfectly 
  pre- 
  

   served 
  specimens; 
  posterior 
  margins 
  of 
  scales 
  scalloped 
  or 
  entire; 
  

   teeth 
  in 
  many 
  rows 
  on 
  the 
  premaxillaries 
  and 
  on 
  the 
  lower 
  jaw; 
  lower 
  

   jaw 
  largely 
  included 
  in 
  upper 
  when 
  mouth 
  is 
  closed; 
  first 
  dorsal 
  origin 
  

   over 
  anal 
  origin; 
  the 
  former 
  equal 
  distance 
  between 
  caudal-fin 
  base 
  

   and 
  rear 
  of 
  head; 
  there 
  are 
  four 
  glandular 
  depressions, 
  very 
  clear, 
  on 
  

   the 
  upper 
  side 
  of 
  snout 
  ; 
  dorsal 
  rays 
  8, 
  anal 
  19, 
  pectoral 
  14, 
  scales 
  45 
  

   and 
  vertebrae 
  19 
  + 
  23=42. 
  

  

  The 
  number 
  of 
  vertebrae 
  in 
  M. 
  martinica 
  19 
  + 
  23, 
  and 
  the 
  four 
  gland- 
  

   ular 
  depressions 
  indicate 
  clearly 
  that 
  the 
  types 
  of 
  martinica 
  are 
  the 
  

   same 
  species 
  as 
  has 
  been 
  currently 
  passing 
  under 
  the 
  names 
  Kirtlandia 
  

   vagrans 
  or 
  Memhras 
  vagrans. 
  The 
  only 
  other 
  known 
  genus 
  with 
  which 
  

   Memhras 
  could 
  be 
  confused 
  is 
  Adeno'ps^ 
  but 
  the 
  number 
  of 
  vertebrae 
  is 
  

   14 
  to 
  16 
  + 
  24 
  to 
  26 
  and 
  the 
  anus 
  is 
  farther 
  forward 
  in 
  Adenops. 
  

  

  The 
  generic 
  diagnosis 
  of 
  3Iemhras 
  was 
  based 
  on 
  the 
  information 
  

   furnished 
  by 
  Dr. 
  Bertin 
  ; 
  on 
  the 
  lectotype,

   (genotyf)e 
  of 
  Kirtlandia) 
  ; 
  and 
  on 
  numerous 
  other 
  lots 
  from 
  the 
  At- 
  

   lantic 
  and 
  Gulf 
  coasts 
  of 
  the 
  United 
  States, 
  under 
  so 
  many 
  catalog 
  

   numbers 
  that 
  it 
  is 
  not 
  practical 
  to 
  list 
  them 
  here. 
  

  

  I 
  have 
  not 
  been 
  able 
  to 
  locate 
  the 
  types 
  of 
  Menidia 
  vagrans 
  lacinata 
  

   Swain 
  but 
  presume 
  that 
  lacinata 
  is 
  a 
  synonym 
  of 
  vagrans^ 
  since 
  I 
  find 
  

   in 
  this 
  genus 
  only 
  a 
  single 
  species, 
  which 
  forms 
  subspecies 
  ^ 
  that 
  inter- 
  

   grade 
  throughout 
  its 
  range. 
  The 
  latter 
  taxonomic 
  units 
  here 
  have 
  not 
  

   been 
  entirely 
  clarified 
  as 
  yet.
