  The 
  fl^attened 
  base 
  of 
  this 
  unique 
  shell 
  is 
  somewhat 
  peculiar. 
  The 
  

   mouth 
  is 
  likewise 
  proportionately 
  small, 
  and 
  the 
  whorls 
  very 
  markedly 
  

   gradate. 
  It 
  may 
  possibly 
  be 
  ultimately 
  relegated 
  to 
  the 
  Pi/rgiscus 
  

   section 
  of 
  TurloniUa, 
  but, 
  though 
  somewhat 
  anomalous, 
  we 
  think 
  it 
  

   bears 
  an 
  affiwity

  The 
  type 
  of 
  the 
  genus, 
  and 
  not 
  usually 
  showing 
  much 
  variation, 
  but 
  

   a 
  very 
  elongate 
  form, 
  with 
  one 
  or 
  two 
  more 
  whorls, 
  and 
  narrower 
  

   proportionately, 
  was 
  dredged 
  off 
  Mussandam. 
  These 
  specimens 
  have 
  

   an 
  olivaceous 
  epidermis, 
  and 
  may 
  perhaps 
  be 
  distinct.

  Since 
  the 
  original 
  description 
  was 
  written, 
  fourteen 
  years 
  ago, 
  

   I 
  have 
  been 
  shown 
  by 
  Mr. 
  Abercrombie 
  a 
  great 
  many 
  examples, 
  some 
  

   measuring 
  alt. 
  8-75, 
  diam. 
  2 
  mm., 
  thus 
  much 
  surpassing 
  the 
  type 
  in 
  

   magnitude. 
  In 
  all 
  other 
  respects 
  the 
  shells 
  are 
  the 
  same.

   rocks 
  at 
  low 
  water, 
  and 
  at 
  7 
  fathoms. 
  

  

  A 
  somewhat 
  protean 
  species, 
  and 
  one 
  which 
  requires 
  further 
  study 
  

   than 
  it 
  has 
  yet 
  received.

  occurs 
  in 
  

   these

  The 
  only 
  examples 
  I 
  have 
  come 
  from 
  Australia. 
  It 
  

   was 
  reported 
  by 
  Mr.

  from

  but 
  I 
  have 
  not 
  seen 
  

   specimens.
