  Examination 
  of 
  other 
  portions 
  of 
  the 
  Islands, 
  and 
  particularly 
  the 
  use 
  

   of 
  the 
  dredge 
  at 
  various 
  depths 
  of 
  the 
  ocean, 
  will 
  certainly 
  reveal 
  many 
  

   other 
  forms. 
  

  

  For 
  subsequent 
  reference, 
  I 
  have 
  here 
  tabulated 
  the 
  characters 
  of 
  the 
  

   whole 
  family. 
  

  

  Sub-class 
  Entomostraca. 
  

  

  Lei/ion 
  I. 
  Lophyropoda. 
  Branchiae 
  attached 
  to 
  the 
  organs 
  of 
  the 
  mouth 
  ; 
  

   legs 
  few, 
  not 
  exceeding 
  five 
  pairs, 
  serving 
  for 
  locomotion 
  ; 
  articulations 
  

   mostly 
  more 
  or 
  less 
  cylindrical; 
  antennae 
  two 
  pau'S, 
  one 
  pair 
  used 
  as 
  organs 
  

   of 
  motion. 
  

  

  Order 
  I. 
  Ostracoda. 
  Shell 
  consisting 
  of 
  2 
  valves, 
  entirely 
  enclosing 
  the 
  

   body 
  ; 
  feet 
  1-3 
  pairs, 
  adapted 
  for 
  progression 
  ; 
  no 
  external 
  ovary. 
  

  

  Sect. 
  I. 
  Podocopa. 
  Inferior 
  anteunse 
  simple, 
  subpediform, 
  geniculate, 
  

   clawed 
  at 
  the 
  end. 
  

  

  Fam. 
  1. 
  Cypridffi. 
  Superior 
  antennae 
  mostly 
  seven 
  -jointed, 
  with 
  a 
  

   dense 
  brush 
  of 
  long 
  setae 
  ; 
  eye 
  single 
  ; 
  feet 
  two 
  pairs, 
  the 
  last 
  bent 
  up 
  

   between 
  the 
  valves 
  ; 
  abdominal 
  rami 
  two, 
  elongate, 
  clawed 
  at 
  the 
  end. 
  

  

  Genus 
  I. 
  Cypris, 
  Milller. 
  

   Upper 
  antenna 
  seven 
  -jointed, 
  with 
  numerous 
  long 
  plumose 
  setae. 
  

   Lower 
  antennae 
  five-jointed, 
  furnished 
  with 
  a 
  brush 
  of 
  setse, 
  and 
  termi- 
  

   nated 
  by 
  four 
  long, 
  serrated 
  claws-. 
  Second 
  pair 
  of 
  jaws 
  possessing 
  a 
  

   branchial 
  plate, 
  and 
  a 
  sub-conical 
  obscurely 
  -jointed 
  palpus, 
  ending 
  in 
  three 
  

   long 
  setse. 
  Post-abdominal 
  rami 
  long 
  and 
  slender, 
  terminating 
  in 
  two 
  

   strong, 
  curved 
  claws. 
  Animals 
  free-swimming, 
  mostly 
  found 
  in 
  fresh 
  or 
  

   slightly 
  brackish 
  water. 
  

  

  1. 
  Cypris 
  novm-zealanclice., 
  Baird. 
  

  

  Cypris 
  nova-zealandice, 
  Baird. 
  Dieffenbach's 
  N. 
  Z., 
  vol. 
  ii, 
  p. 
  268. 
  

  

  "Shell 
  ovate, 
  elongated, 
  both 
  extremities 
  of 
  the 
  same 
  size, 
  somewhat 
  

   turgid 
  and 
  slightly 
  siuuated 
  in 
  the 
  centre 
  of 
  anterior 
  margin, 
  white, 
  smooth 
  

   and 
  shining, 
  perfectly 
  free 
  from 
  hairs." 
  

  

  This 
  may 
  be 
  the 
  species 
  described 
  next, 
  as 
  the 
  valves 
  bleach 
  after 
  the 
  

   animal 
  dies, 
  and 
  lose 
  their 
  hairs. 
  The 
  shape, 
  however, 
  is 
  not 
  quite 
  the 
  

   same, 
  and 
  the 
  whole 
  description 
  is 
  too 
  meagre 
  to 
  found 
  any 
  identification 
  

   upon. 
  

  

  The 
  following 
  three 
  species 
  belong 
  to 
  Brady's 
  Section 
  a, 
  and 
  agree 
  in 
  the 
  

   following 
  characters 
  : 
  — 
  

  

  "Setse 
  of 
  lower 
  antenna 
  plumose, 
  subequal, 
  reaching 
  about 
  as 
  far 
  as, 
  

   or 
  only 
  slightly 
  beyond, 
  the 
  apex 
  of 
  the 
  terminal 
  claws. 
  Second 
  foot 
  

   terminating 
  in 
  a 
  short, 
  hooked 
  claw, 
  and 
  one 
  or 
  more 
  moderately 
  long 
  

   setae."
