  "Six 
  dead 
  specimens. 
  In 
  one 
  of 
  them 
  the 
  longitudinal 
  ribs 
  are 
  

   wanting; 
  it 
  has 
  stronger 
  spiral 
  ridges, 
  and 
  is 
  smaller 
  than 
  the 
  other 
  

   specimens. 
  

  

  " 
  This 
  species 
  was 
  figured 
  in 
  Sir 
  Wyville 
  Thomson's 
  Depths 
  of 
  the 
  

   Sea 
  (1873), 
  p. 
  463, 
  fig. 
  76, 
  under 
  my 
  name 
  of 
  Biiccinopsis 
  striata. 
  

   As 
  the 
  operculum 
  of 
  the 
  present 
  species 
  is 
  not 
  known, 
  it 
  is 
  more 
  than 
  

   questionable 
  whether 
  it 
  can 
  be 
  placed 
  in 
  Buccmopsis, 
  and 
  I 
  must 
  

   provisionally 
  leave 
  it 
  in 
  Buccinum. 
  It 
  may 
  be 
  allied 
  to 
  B. 
  ahyssorum 
  

   of 
  Verrill, 
  as 
  well 
  as 
  to 
  B. 
  Baerii 
  of 
  Middendorff."
