   condition. 
  

  

  I. 
  Karachi; 
  alive, 
  but 
  very 
  rarely 
  found. 
  

  

  A 
  very 
  elegant, 
  delicate 
  species, 
  and 
  I 
  am 
  not 
  even 
  yet 
  quite 
  sure 
  

   as 
  to 
  its 
  systematic 
  position.

  Another 
  beautiful

  Agatha,

  (representative

  Hah. 
  — 
  Bombay 
  (Abercrombie). 
  Commoner 
  than 
  A. 
  filia, 
  but 
  

   specimens 
  are 
  hardly 
  ever 
  found 
  in 
  perfect 
  condition, 
  owing 
  to 
  their 
  

   fragility. 
  

  

  A 
  pellucid, 
  milky- 
  white 
  Agatha, 
  differing 
  from 
  the 
  other 
  Bombay 
  

   species 
  {^A. 
  filia, 
  Melvill) 
  in 
  its 
  marked 
  narrowness 
  of 
  whorl 
  in 
  

   proportion 
  to 
  its 
  length 
  ; 
  in 
  most 
  other 
  particulars, 
  e.g. 
  gradation 
  

   of 
  whorl, 
  transparent 
  consistency, 
  nuclear 
  whorls, 
  and 
  form 
  of 
  

   mouth, 
  they 
  are 
  almost 
  identical. 
  Several 
  examples, 
  all 
  alike. 
  

  

  Whether 
  Amathis 
  be 
  entitled 
  to 
  rank 
  as 
  a 
  genus 
  on 
  its 
  own 
  merits.
