  The 
  genera 
  Holocentrum 
  and 
  Myripristis, 
  shore 
  fishes 
  with 
  long 
  spinous 
  dorsal, 
  

   should 
  probably 
  be 
  regarded 
  as 
  forming 
  a 
  family 
  distinct 
  from 
  the 
  Berycidw, 
  which 
  

   are 
  deep-sea 
  fishes 
  w^th 
  a 
  single 
  dorsal, 
  provided 
  with 
  but 
  few 
  spines, 
  or 
  even 
  with 
  

   none.

  This 
  species, 
  called 
  in 
  the 
  text 
  Holocentrum 
  pentacanthum, 
  should 
  apparently 
  

   stand 
  as 
  Holocentrum 
  ascensione 
  (Osbeck). 
  In 
  life, 
  an 
  oblique 
  white 
  bar 
  descends 
  back- 
  

   ward 
  from 
  the 
  eye 
  ; 
  this 
  disappears 
  entirely 
  in 
  spirits.

  the 
  synonymy,

   (Cuvier, 
  Regne 
  Animal; 
  type 
  Myripristis 
  jacobus 
  Cuv. 
  & 
  Val.) 
  

  

  This 
  genus 
  is 
  very 
  closely 
  related 
  to 
  Holocentrum, 
  differing 
  externally, 
  chiefly 
  in 
  

   the 
  absence 
  of 
  the 
  large 
  spine 
  at 
  the 
  angle 
  of 
  the 
  preopercle. 
  The 
  air-bladder 
  is 
  

   divided 
  into 
  two 
  parts 
  by 
  a 
  transverse 
  constriction, 
  and 
  the 
  pyloric 
  cceca 
  are 
  rather
