  filamentous, 
  each 
  of 
  2 
  rays 
  separate 
  at 
  tip, 
  their 
  bases 
  not 
  close 
  

   together, 
  inserted 
  behind 
  tip 
  of 
  humeral 
  symphysis; 
  pseudobranchiae 
  

   present; 
  pyloric 
  coeca 
  finger-like 
  in 
  a 
  ring 
  around 
  the 
  pylorus, 
  and 
  in 
  

   2 
  short 
  rows 
  along 
  neighboring 
  part 
  of 
  gut. 
  

  

  There 
  are 
  slight 
  variations 
  in 
  the 
  form 
  and 
  armature 
  of 
  the 
  pre- 
  

   opercle. 
  In 
  several 
  species 
  including 
  the 
  type 
  there 
  is 
  a 
  single 
  spine- 
  

   like 
  tip 
  at 
  or 
  near 
  the 
  angle 
  of 
  the 
  preopercle; 
  in 
  others 
  there 
  is 
  an 
  

   additional 
  small 
  spine 
  above 
  the 
  fii'st, 
  which 
  character 
  is 
  used 
  as 
  

   the 
  basis 
  of 
  the 
  genus 
  Watasea. 
  We 
  find 
  a 
  corresponding 
  amount 
  

   of 
  variation 
  in 
  some 
  of 
  the 
  other 
  closely 
  related 
  genera 
  and 
  do 
  not 
  

   consider 
  this 
  character 
  of 
  generic 
  value.
