  Four 
  specimens 
  from 
  the 
  above 
  localities 
  appear 
  to 
  agree 
  fairly 
  

  

  with 
  the 
  superficial 
  description 
  given 
  by 
  the 
  zoologists 
  of 
  the 
  

  

  ' 
  Astrolabe,' 
  whose 
  examples 
  were 
  obtained 
  at 
  Port 
  Dorey 
  in

  The 
  specimens 
  from 
  Port 
  Denison, 
  which 
  may 
  belong 
  to 
  this 
  

   species, 
  are 
  very 
  like 
  T. 
  norveyicus 
  and 
  T. 
  palmulata 
  externally. 
  The 
  

   sculpture 
  is 
  similar, 
  but 
  the 
  notch 
  or 
  angle 
  in 
  the 
  anterior 
  side 
  is 
  

   not 
  quite 
  so 
  deep 
  as 
  in 
  the 
  former. 
  The 
  interior 
  of 
  the 
  valves 
  has 
  

   not 
  a 
  distinct 
  ridge 
  marking 
  off 
  the 
  posterior 
  lobe. 
  The 
  pallets, 
  

   wanting 
  in 
  the 
  specimens 
  before 
  me, 
  are 
  said 
  to 
  be 
  " 
  elongate, 
  

   slightly 
  curved, 
  penniform."

  Four

  and 
  others 
  in 
  the 
  British 
  

   Museum, 
  also 
  from 
  New 
  8outh 
  Wales, 
  I 
  am 
  unable 
  to 
  separate 
  from 
  

   this 
  northern 
  form. 
  Dr. 
  Gwyn 
  Jeffreys 
  and 
  others 
  have 
  also 
  failed 
  

   to 
  distiuguish 
  Australian 
  from 
  Arctic 
  examples.
