  This 
  peculiar 
  perch-like 
  fish 
  inhabits 
  the 
  fresh 
  and 
  brack- 
  

   ish 
  waters 
  of 
  Turner's 
  creek, 
  near 
  Berlin, 
  Worcester 
  county. 
  

   It 
  loves 
  dark 
  streams 
  with 
  muddy 
  bottoms, 
  on 
  which 
  it 
  settles, 
  

   darting 
  away 
  with 
  great 
  vigor 
  when 
  disturbed. 
  Shallow 
  

   places, 
  heated 
  by 
  the 
  hot 
  rays 
  of 
  the 
  sun, 
  form 
  the 
  desired 
  

   resorts.
