  Bassogigas 
  Gill 
  ms., 
  in 
  Goode 
  and 
  Bean, 
  Oceanic 
  Ichthyology, 
  1895, 
  p. 
  328, 
  

   pterotus. 
  

  

  This 
  genus 
  is 
  closely 
  related 
  to 
  Baratlirodemus, 
  distmguished 
  by 
  

   the 
  shorter 
  snout 
  which 
  does 
  not 
  project 
  beyond 
  the 
  terminal 
  mouth 
  

   and 
  is 
  not 
  dilated; 
  by 
  the 
  less 
  elevated, 
  more 
  robust 
  form 
  of 
  the 
  body. 
  

   The 
  head 
  is 
  fu-mer, 
  less 
  spongy, 
  the 
  lower 
  preopercular 
  margin 
  is 
  

   free, 
  the 
  opercular 
  spine 
  is 
  strong 
  and 
  each 
  ventral 
  is 
  divided 
  nearly 
  

   to 
  its 
  base. 
  Except 
  for 
  traces 
  of 
  a 
  few 
  rudimentary 
  pores 
  near 
  head, 
  

   the 
  lateral 
  line 
  is 
  indistinguishable.
