  frequently, 
  and 
  often 
  in 
  good 
  condition, 
  after 
  stormy 
  weather, 
  thence 
  

   southward 
  to 
  Goa 
  and 
  Panjiiu 
  (Lieut.

  As 
  found 
  out 
  by 
  Mr. 
  Sylvanus 
  Hanley 
  when 
  investigating 
  the 
  

   actual 
  types 
  of 
  Linnoeus, 
  this 
  species 
  must 
  bear 
  the 
  name 
  javana, 
  in 
  

   contradistinction 
  to 
  the 
  species 
  that 
  formerly 
  held 
  it 
  on 
  false 
  

   premises. 
  That 
  known 
  now 
  as 
  tornata. 
  Dillwyn, 
  is 
  an 
  almost 
  entirely 
  

   smooth 
  shell, 
  while 
  the 
  one 
  under 
  discussion 
  exactly 
  conforms 
  to 
  

   LinnsDus' 
  description 
  in 
  the 
  Systema 
  Naturoi, 
  as 
  follows:

  Simillimus

  Dredged

  (Watson),

  fairly 
  distributed 
  

   in

  This 
  was 
  at 
  first 
  placed 
  by 
  me 
  in 
  the 
  sub-genus 
  Gemmula, 
  but 
  its 
  

   similarity 
  to 
  S. 
  tuherculata. 
  Gray, 
  is 
  so 
  great 
  that 
  I 
  have 
  transferred 
  

   it 
  as 
  above. 
  It 
  is 
  a 
  bt^autiful 
  species, 
  and 
  the 
  author 
  remarks 
  thus 
  

   upon 
  it: 
  "A 
  form 
  of 
  charming 
  shape 
  and 
  purity, 
  with 
  whorls 
  

   strongly 
  excavated 
  above, 
  and 
  a 
  row 
  of 
  upright 
  oblong 
  tubercles 
  

   encircling 
  their 
  bases, 
  and 
  two 
  small 
  contiguous 
  keels 
  around 
  them 
  

   just 
  below 
  the 
  suture." 
  This 
  type 
  is 
  Mauritian, 
  and 
  now 
  figured 
  for 
  

   the 
  first 
  time. 
  I 
  suspect 
  it 
  to 
  be 
  a 
  pale-wliite 
  (occasionally 
  suffused 
  

   with 
  lilac) 
  deep-sea 
  variety 
  of 
  the 
  stouter 
  and 
  coarser 
  tiiberciilata,

  A 
  common 
  species 
  at 
  5-30 
  fathoms, 
  soft 
  mud, 
  the 
  most 
  

   perfectly 
  developed

  greater 
  depth.

  Very 
  worn 
  specimens, 
  at 
  first 
  confused 
  

   with 
  Clavatula 
  virginea, 
  Beck, 
  a 
  "West 
  African 
  species. 
  

  

  This 
  seems 
  locally 
  very 
  abundant. 
  It 
  extends 
  to 
  China 
  on 
  the 
  

   east, 
  and 
  to 
  Aden 
  on 
  the 
  west. 
  

  

  Surcula 
  vepallida, 
  von 
  Martens, 
  described 
  as 
  a 
  Leucosyrinx,^ 
  came 
  

   from 
  Aden 
  ; 
  and 
  has 
  since 
  been 
  dredged 
  at 
  300 
  fathoms 
  off 
  the 
  

   Coromandel 
  Coast 
  by 
  the 
  Investigator^ 
  Accordingly 
  it 
  probably 
  will 
  

   be 
  found 
  to 
  occur 
  in 
  the 
  Gulf 
  of 
  Oman.
