  Owing 
  to 
  an 
  oversight, 
  an 
  important 
  species 
  of 
  Morum 
  was 
  left 
  out 
  

   of 
  the 
  enumeration 
  just 
  published/ 
  viz. 
  : 
  

  

  Morum 
  macandeewi

  The 
  author 
  I'emarks 
  of 
  this 
  interesting 
  and 
  fine 
  species, 
  as 
  compared 
  

   with 
  its 
  nearest 
  ally, 
  M. 
  'ponderosum 
  (Hanley), 
  that 
  it 
  is 
  much 
  higher 
  

   in 
  the 
  spire, 
  the 
  nodules 
  on 
  the 
  body-whorl 
  also 
  being 
  smaller 
  and 
  less 
  

   prominent. 
  From 
  M. 
  cancellatum 
  (Sowb.) 
  it 
  differs 
  in 
  being 
  more 
  

   pyriform, 
  with 
  greater 
  degree 
  of 
  gibbosity, 
  the 
  transverse 
  ridges 
  

   not 
  raised 
  into 
  echinations 
  on 
  the 
  ribs, 
  while 
  the 
  coloration 
  consists 
  

   in 
  variegation 
  of 
  white 
  and 
  brown 
  marking. 
  It 
  was 
  discovered 
  by 
  

   Dr. 
  Hungerford, 
  in 
  whose 
  collection 
  were 
  two 
  specimens. 
  It 
  will 
  

   probably 
  be 
  found 
  not 
  infrequent 
  in 
  Japanese 
  waters, 
  several 
  

   examples 
  having 
  been 
  dredged 
  by 
  Mr. 
  Hirase 
  during 
  the 
  past 
  few 
  

   years. 
  With 
  this 
  addition, 
  the 
  number 
  of 
  recent 
  species 
  of 
  this 
  

   circumscribed 
  genus 
  only 
  totals 
  eleven 
  altogether. 
  

  

  Regarding 
  the 
  locality 
  of 
  Morum 
  dennisoni 
  (Reeve) 
  as 
  given 
  ayitea, 
  

   p. 
  72, 
  "Reported 
  fi'om 
  Guadaloupe, 
  but 
  most 
  probably 
  an 
  Eastern 
  

   species," 
  Dr. 
  Dall 
  has 
  kindly 
  communicated 
  witli 
  me 
  recently 
  on 
  this 
  

   subject, 
  and 
  considers 
  the 
  West 
  Indian 
  habitat 
  undoubtedly 
  the 
  

   correct 
  one 
  ; 
  the 
  species 
  having 
  been 
  dredged 
  recently 
  off 
  the 
  

   Central 
  American 
  coast, 
  though 
  only 
  in 
  very 
  small 
  quantity.
