  Tt 
  is 
  at 
  once 
  apparent 
  from 
  this 
  Table 
  that 
  by 
  far 
  the 
  largest 
  

   number 
  of 
  species 
  ((J4 
  in 
  all) 
  have 
  been 
  obtained 
  from 
  Torres 
  Straits 
  ; 
  

   that 
  is, 
  no 
  doubt, 
  partly 
  due 
  to 
  the 
  large 
  number 
  of 
  dredgings 
  taken 
  

   and 
  the 
  number 
  of 
  minor 
  localities 
  investigated 
  here. 
  The 
  Renieridse 
  

   are 
  the 
  only 
  family 
  of 
  Silicea 
  or 
  Ceratosa 
  which 
  are 
  not 
  strongly 
  

   represented. 
  The 
  forms 
  most 
  abundant 
  here 
  axclotrochota 
  purpurea. 
  

  

  t 
  It 
  is 
  uncertain 
  to 
  which 
  variety 
  the 
  locality 
  given 
  by 
  Hackel 
  refers.
