  examination 
  of 
  the 
  specimens 
  * 
  * 
  enables 
  me 
  to 
  refer 
  them 
  to 
  the 
  Protozoa 
  

   class, 
  Spon^idje, 
  or 
  sponges 
  ": 
  and 
  he 
  concludes 
  by 
  saying 
  : 
  " 
  Its 
  generic 
  relations 
  

   will, 
  I 
  think, 
  be 
  with 
  Hyalonema 
  and 
  Euplectella. 
  both 
  sponges 
  of 
  the 
  Pacific." 
  

  

  The 
  foregoing 
  is 
  all 
  that 
  I 
  find 
  relating 
  to 
  the 
  "switches," 
  prior 
  to 
  my 
  re- 
  

   marks 
  as 
  above; 
  I 
  was 
  not 
  aware, 
  at 
  the 
  time, 
  that 
  anything 
  bad 
  appeared 
  on 
  

   the 
  subject, 
  other 
  than 
  the 
  remarks 
  of 
  Dr. 
  Blake, 
  and 
  that 
  of 
  Mr. 
  Sclater'a 
  

   article, 
  to 
  which 
  Dr. 
  Blake 
  referred. 
  Mr. 
  Sclater's 
  article 
  I 
  had 
  not 
  read, 
  but 
  

   had 
  casually 
  glanced 
  at 
  the 
  drawing 
  of 
  the 
  so-called 
  fish. 
  

  

  But 
  having 
  expended 
  so 
  much 
  time 
  prior 
  to 
  an 
  examination 
  of 
  the 
  files 
  of 
  

   " 
  Nature," 
  I 
  considered 
  it 
  a 
  matter 
  of 
  sufficient 
  interest 
  to 
  warrant 
  a 
  review 
  of 
  

   the 
  subject, 
  and 
  present 
  the 
  same 
  to 
  the 
  Academy. 
  

  

  As 
  to 
  what 
  these 
  animal 
  "switches" 
  belong 
  to, 
  it 
  will 
  be 
  seen 
  that 
  Dr. 
  Blake, 
  

   whose 
  examination 
  of 
  their 
  substance 
  microscopically 
  appears 
  to 
  have 
  been 
  

   quite 
  thorough, 
  places 
  them 
  with 
  the 
  sponges.' 
  Mr. 
  Sclater 
  does 
  not 
  commit 
  

   himself, 
  but 
  conditionally 
  refers 
  them 
  to 
  the 
  fishes. 
  Dr. 
  Gray 
  described 
  (it) 
  

   them 
  as 
  a 
  new 
  species 
  of 
  Osteocella, 
  whatever 
  that 
  may 
  be, 
  (perhaps 
  a 
  Pennatu- 
  

   iid) 
  while 
  Professors 
  Kolliker, 
  Flower, 
  Milne-Edwards, 
  Mr. 
  Mosely, 
  Principal 
  

   Dawson, 
  Prof. 
  Verrill, 
  Mr. 
  Whiteaves, 
  Mr. 
  Dall 
  and 
  myself, 
  regard 
  them 
  as 
  

   belonging 
  to 
  a 
  species 
  of 
  Alcyonoid 
  polyp, 
  related 
  or 
  pertaining 
  to 
  the 
  group 
  

   PennatulidcE. 
  

  

  On 
  reviewing 
  the 
  above, 
  it 
  will 
  be 
  noticed 
  that 
  the 
  various 
  parties 
  who 
  pre- 
  

   sented 
  the 
  specimens, 
  both 
  of 
  the 
  Burrard's 
  Inlet 
  forms 
  and 
  that 
  from 
  West 
  

   Australia, 
  state 
  that 
  they 
  are 
  bones 
  of, 
  or 
  belong 
  to 
  fishes, 
  implying 
  that 
  they 
  

   are 
  a 
  part 
  of 
  free-swimming 
  animals 
  ; 
  while 
  some 
  species 
  of 
  the 
  Pennatulacea 
  

   "live 
  a 
  floating 
  life 
  in 
  the 
  ocean," 
  it 
  is 
  not 
  unlikely 
  that 
  others 
  may 
  not 
  be 
  con- 
  

   stantly 
  stationary, 
  or, 
  if 
  I 
  may 
  use 
  the 
  word, 
  are 
  not 
  planted, 
  all 
  of 
  the 
  time 
  ; 
  

   and 
  while 
  floating 
  might 
  be 
  mistaken 
  for 
  fishes, 
  more 
  especially 
  if 
  numerous 
  

   specimens 
  were 
  seen 
  moving 
  in 
  the 
  water, 
  coincident 
  with 
  the 
  presence 
  of 
  a 
  

   school 
  of 
  fishes. 
  

  

  In 
  conclusion, 
  I 
  would 
  state 
  my 
  belief 
  that 
  the 
  much-discussed 
  switches 
  are 
  a 
  

   species 
  of 
  Umbellularia, 
  for 
  which 
  Dr. 
  Gray's 
  specific 
  name 
  might 
  be 
  adopted, 
  

   and 
  attached 
  to 
  the 
  specimens 
  from 
  Burrard's 
  Inlet, 
  in 
  the 
  Academy's 
  collection.
