  otlier, 
  five 
  in 
  number, 
  distributed 
  over 
  a 
  great 
  portion 
  of 
  the 
  eastern 
  

   tropics, 
  having 
  been 
  noticed 
  in

  (A..

  (Iledley), 
  

   Persian

   (Sykes), 
  better 
  known 
  by 
  the 
  name 
  of 
  hystrix 
  (Jan). 
  In 
  this 
  species, 
  

   as 
  in 
  so 
  many 
  true 
  Clathurinse, 
  the 
  nuclear 
  whorls 
  are 
  bulbous, 
  

   vitreous, 
  closely 
  spirally 
  microscopically 
  striate 
  or 
  cancellate.

   Differs 
  from

  (Sm.), 
  according 
  to 
  the 
  author 
  (loc. 
  cit., 
  

   p. 
  297), 
  by 
  its 
  longer 
  spire, 
  narrower 
  form, 
  closer 
  reticulation, 
  and 
  

   smooth 
  apical 
  whorls, 
  AH 
  tlie 
  species 
  seem 
  very 
  nearly 
  allied. 
  Also 
  

   reported 
  from 
  Japan. 
  

  

  This 
  does 
  not 
  occur 
  in 
  the 
  Townsendlan 
  gatherings. 
  I 
  can 
  hardly 
  

   separate 
  it 
  from 
  its 
  too 
  near 
  ally, 
  CI. 
  reliculoHa. 
  In 
  ray 
  opinion, 
  the 
  

   apical 
  whorls 
  of 
  the 
  type 
  (here 
  figured) 
  are 
  worn, 
  and 
  the 
  fine 
  delicate 
  

   radiate 
  ribs 
  obliterated. 
  Should 
  it 
  be 
  decided 
  in 
  future 
  to 
  unite 
  these 
  

   two 
  species, 
  both 
  described 
  in 
  tiie 
  same 
  paper, 
  the 
  present 
  species 
  has 
  

   precedence 
  by 
  one

  This 
  species 
  differs 
  from 
  its 
  congeners 
  in 
  its 
  greater 
  ventricosity 
  and 
  

   roundness 
  of 
  whorl, 
  the 
  number 
  of 
  longitudinal 
  costae 
  on 
  the 
  body- 
  

   whorl 
  is 
  sixteen 
  in 
  the 
  specimen 
  figured, 
  the 
  spiral 
  acute 
  lirations 
  

   are 
  also 
  moi-e 
  frequent 
  than 
  obtain 
  in 
  si/kesii 
  or

  The 
  

   apical 
  whorls 
  are 
  microscopically 
  longitudinally 
  costellate, 
  four 
  in 
  

   number. 
  The 
  tyi)e 
  possesses 
  a 
  greater 
  number 
  of 
  ribs 
  than 
  obtains 
  

   in 
  the 
  more 
  recently 
  collected 
  examples, 
  but 
  I 
  cannot 
  further 
  

   separate 
  them 
  specifically.
