  under

  A 
  technical

  his 
  Eeport 
  on 
  the 
  Comatulidae 
  of 
  the 
  ' 
  Chal- 
  

   lenger' 
  Collection. 
  It 
  is

  a

  A 
  small 
  specimen, 
  from 
  Warrior 
  Reef, 
  was 
  determined 
  for 
  me 
  by 
  

   Mr. 
  Carpenter 
  ; 
  another 
  from 
  Port 
  Molle 
  has 
  less 
  than 
  20 
  arms, 
  as 
  

   in 
  some 
  of 
  the 
  specimens 
  in 
  the 
  Paris 
  Museum. 
  It 
  is 
  of 
  interest 
  to 
  

   note 
  that 
  this 
  appears 
  to 
  be, 
  like 
  A. 
  carinata, 
  a 
  species 
  of 
  exceedingly 
  

   wide 
  range, 
  for 
  Mr. 
  Carpenter 
  found 
  two 
  specimens 
  of 
  it 
  from 
  Peru 
  

   in 
  the 
  collection 
  of 
  the 
  Hamburg 
  Museum.
