  •The 
  genus 
  DalUa, 
  although 
  agreeing 
  in 
  many 
  external 
  characters 
  with 
  Umbra, 
  

   has 
  very 
  little 
  affinity 
  with 
  that 
  group 
  or 
  any 
  other 
  of 
  our 
  fishes. 
  Its 
  skeleton 
  is 
  so 
  

   peculiar 
  in 
  structure 
  that 
  it 
  has 
  been 
  taken 
  by 
  Dr. 
  Gill 
  as 
  the 
  representative 
  of 
  a 
  

   peculiar 
  order 
  or 
  suborder, 
  Xenomi, 
  which 
  is 
  thus 
  defined 
  : 
  

  

  "Teleosfcs 
  with 
  the 
  scapular 
  arch 
  free 
  from 
  the 
  cranium 
  laterally 
  and 
  only 
  abut- 
  

   ting 
  on 
  it 
  behind, 
  coracoids 
  represented 
  by 
  a 
  simple 
  cartilaginous 
  plate 
  without 
  de- 
  

   veloped 
  actinosts, 
  and 
  with 
  the 
  intermaxillary 
  and 
  supramaxillary 
  bones 
  coalescent."

  This 
  genus 
  differs 
  from 
  Muraena 
  chiefly 
  in 
  the 
  reduction 
  of 
  the 
  fins 
  to 
  a 
  short 
  fold, 
  

  

  surrounding
