  In 
  this

  the 
  scales 
  are 
  smaller, 
  the 
  ventrals 
  longer, 
  the 
  body 
  

   more 
  robust, 
  opercular 
  spine 
  weaker 
  and 
  coloration 
  lighter 
  than 
  in 
  

   the 
  type 
  of 
  B. 
  compressus 
  Giinther. 
  His 
  example, 
  5.5 
  inches 
  long, 
  

   taken 
  at 
  station 
  205, 
  Philippine 
  Islands, 
  had 
  longer 
  ventrals 
  as 
  in
