  here 
  omit 
  Gymnelis 
  stigma. 
  It 
  is 
  probably 
  based 
  on 
  an 
  inaccurate 
  description 
  of 
  

   Gymnelis 
  viridis. 
  If, 
  however, 
  really 
  possessing 
  scales, 
  it 
  may 
  belong 
  to 
  the 
  Antarctic 
  

   genus 
  Maynea 
  (Cunningham), 
  which 
  differs 
  from 
  Lycodes 
  chiefly 
  in 
  the 
  absence 
  of 
  

   ventrals.

   This

  is 
  a

  suggest 
  the 
  provisional 
  name 
  Cerdalidce 
  for 
  two 
  closely 
  related 
  genera, 
  Cerdale 
  

   Jordan 
  & 
  Gilbert, 
  and 
  Microdesmus 
  Giinther, 
  which 
  seem 
  to 
  be 
  allied 
  to 
  the 
  Lycodidm, 
  

   differing 
  in 
  the 
  small, 
  slit-like 
  gill 
  openings 
  and 
  in 
  the 
  non-isocercal 
  tail. 
  The 
  three 
  

   known 
  species 
  are 
  scantily 
  represented 
  in 
  collections, 
  and 
  until 
  their 
  osteology 
  is 
  ex- 
  

   amined 
  we 
  cannot 
  be 
  sure 
  as 
  to 
  their 
  relation 
  to 
  the 
  Lycodido3, 
  Congrogadidw, 
  and 
  

   BrotuUdce.
