  in 
  April. 
  E. 
  Yon 
  Martens 
  

   utilized 
  the 
  name 
  in 
  Die 
  Reliceen, 
  2nd 
  ed., 
  p. 
  72, 
  for 
  a 
  section 
  of 
  

   Helix, 
  the 
  only 
  species 
  being 
  H. 
  co7icoIor 
  ; 
  while 
  Mayer 
  associated 
  it 
  

   with 
  a 
  genus 
  of 
  fossil 
  Streptoneura 
  in 
  the 
  Journal 
  c/e 
  Conchyliologie, 
  

   pt. 
  iii, 
  bearing 
  the 
  date 
  July, 
  1860,^ 
  but 
  probably 
  not 
  published 
  until 
  

   1861. 
  I 
  have 
  been 
  unable 
  to 
  find 
  the 
  actual 
  date 
  at 
  which 
  it 
  was 
  

   issued, 
  but 
  the 
  copy 
  in 
  the 
  British 
  Museum 
  is 
  stamped 
  with 
  the 
  date 
  

   "July 
  5th, 
  1861", 
  and 
  as 
  this 
  publication 
  has, 
  I 
  believe, 
  invariably 
  

   been 
  published 
  long 
  after 
  the 
  dates 
  printed 
  on 
  the 
  covers, 
  it 
  may 
  safely 
  

   be 
  assumed 
  that 
  Mayer's 
  name 
  has 
  no 
  claim 
  to 
  rank 
  ; 
  since 
  the 
  parts 
  

   of 
  the 
  Ann. 
  Mag. 
  Nat. 
  Hist, 
  have 
  always 
  been 
  issued 
  punctually, 
  

   the 
  only 
  question 
  remains 
  as 
  to 
  the 
  date 
  of 
  Die 
  Heliceen. 
  The 
  

   publisher, 
  Mr. 
  W. 
  Engelmann, 
  of 
  Leipzig, 
  on 
  being 
  questioned 
  on 
  this 
  

   point, 
  obligingly 
  replied 
  that 
  the 
  records 
  of 
  the 
  firm 
  have 
  not 
  been 
  

   kept 
  so 
  far 
  back, 
  but 
  he 
  is 
  sure 
  the 
  work 
  was 
  not 
  sent 
  out 
  until 
  late 
  in 
  

   the 
  year 
  i860, 
  so 
  that 
  Adams' 
  name 
  undoubtedly 
  has 
  priority, 
  and 
  for 
  

   von 
  Martens' 
  genus 
  I 
  therefore 
  propose 
  the 
  name 
  Zophos, 
  taking 
  as 
  

   the 
  type 
  Helix 
  concolor, 
  Morch, 
  from 
  Porto 
  Rico, 
  Dominica, 
  and 
  

   Guadeloupe. 
  

  

  NiTOE.,^ 
  n.n. 
  

  

  In 
  the 
  same 
  work 
  (p. 
  59) 
  von 
  Martens 
  also 
  defined 
  the 
  genus 
  

   Thalassia, 
  taking 
  as 
  type 
  Helix 
  suhrugata, 
  Pfr. 
  Agassiz 
  in 
  his 
  

   Nomenelator 
  states 
  that 
  Dejean^ 
  published 
  a 
  genus 
  Thalassia, 
  but 
  as 
  

   this 
  work 
  contains 
  no 
  diagnoses 
  or 
  definitions 
  of 
  any 
  of 
  the 
  groups, 
  

   and 
  as 
  moreover 
  the 
  name 
  appears 
  subsequently 
  to 
  have 
  been 
  altered 
  

   to 
  Thalassa, 
  I 
  intended 
  to 
  have 
  retained 
  von 
  Martens' 
  name. 
  Mr. 
  T. 
  

   Iredale, 
  however, 
  has 
  kindly 
  drawn 
  my 
  attention 
  to 
  the 
  fact 
  that 
  

   a 
  genus 
  of 
  birds 
  has 
  been 
  properly 
  defined 
  under 
  the 
  name 
  Thalassia,^ 
  

   and 
  I 
  therefore 
  substitute 
  the 
  above 
  designation. 
  

  

  Cycliscus,^ 
  n.n. 
  

  

  In 
  1850 
  Albers 
  proposed 
  the 
  name 
  Rotula 
  in 
  Die 
  Heliceen, 
  1st 
  ed., 
  

   for 
  a 
  genus 
  containing 
  Helix 
  Bensoni, 
  v. 
  d. 
  Busch, 
  and 
  H 
  detecta, 
  

   Fer., 
  while 
  von 
  Martens 
  in 
  the 
  second 
  edition 
  restricted 
  the 
  genus 
  to 
  

   H. 
  detecta, 
  the 
  other 
  name 
  having 
  proved 
  to 
  be 
  a 
  synonym 
  of 
  

   H. 
  serrula, 
  Bens., 
  a 
  species 
  referred 
  to 
  the 
  genus 
  Kliasiella. 
  The 
  

   name 
  Rotula 
  being 
  preoccupied 
  in 
  Echinoderma 
  (Agassiz, 
  Monographie 
  

   des 
  Scutelles, 
  1841, 
  p. 
  23), 
  Albers' 
  name 
  has 
  to 
  share 
  the 
  fate 
  of 
  the 
  

   preceding 
  two, 
  and 
  Helix 
  detecta, 
  Fer., 
  from 
  the 
  Island 
  of 
  Bourbon 
  

   becomes 
  the 
  type 
  of 
  Cycliscus.
