  new 
  genus 
  

  

  Genotype. 
  — 
  Gobiesox 
  erythrops 
  Gilbert. 
  

  

  This 
  genus 
  is 
  characterized 
  by 
  the 
  groove 
  along 
  the 
  anterior 
  or 
  upper 
  

   margin 
  of 
  the 
  preniiixillary 
  which 
  arches 
  in 
  a 
  convex 
  manner 
  over 
  the 
  

   tip 
  of 
  the 
  snout; 
  the 
  orbits 
  are 
  larger 
  than 
  in 
  any 
  other 
  genus 
  of 
  Amer- 
  

   ican 
  clingfishes, 
  their 
  diameter 
  much 
  greater 
  than 
  the 
  least 
  width 
  of 
  the 
  

   bony 
  interorbital. 
  In 
  addition, 
  the 
  axial 
  dermal 
  flap 
  bcliind 
  the 
  pec- 
  

   toral 
  lin 
  has 
  its 
  dorsal 
  edge 
  attached 
  mucii 
  above 
  the 
  niidbase 
  of 
  pec- 
  

   toral 
  ; 
  the 
  incisorlike 
  teeth 
  at 
  front 
  of 
  lower 
  jaw 
  have 
  smooth 
  tips, 
  and 
  

   lhe.se 
  teeth 
  project 
  forward 
  horizontally 
  and 
  do 
  not 
  oppose 
  the 
  teeth 
  

   at 
  front 
  of 
  upper 
  jaw, 
  whicli 
  are 
  nearly 
  conical; 
  there 
  are 
  no 
  papillae 
  

   around 
  the 
  mouth, 
  although 
  the 
  usual 
  lobelike 
  ridges 
  occur 
  on 
  lower 
  

   jaw 
  and 
  chin; 
  gill 
  membranes 
  are 
  joined 
  at 
  upper 
  edge 
  of 
  pectoral 
  fin 
  

   ba.se 
  or 
  appear 
  to 
  be 
  opposite 
  base 
  of 
  first 
  pecloral 
  fin 
  ray; 
  the 
  free 
  

   posterior 
  margin 
  of 
  fleshy 
  pad 
  on 
  outer 
  surface 
  of 
  pectoral 
  base 
  is 
  con- 
  

   fined 
  to 
  the 
  lower 
  half 
  of 
  that 
  fin 
  and 
  not 
  iibove 
  the 
  thirteenth 
  ray 
  from 
  

   the 
  top. 
  Other 
  characters 
  are 
  tlio.se 
  of 
  the 
  genotype.
