  Allied 
  to 
  T. 
  galactodes 
  and 
  T. 
  Ahercromhiei, 
  Melvill. 
  One 
  of 
  the 
  

   smaller 
  species, 
  but 
  the 
  elegance 
  of 
  its 
  shining 
  close 
  whorls, 
  subangled 
  

   at 
  the 
  upper 
  part, 
  just 
  by 
  the 
  sutures, 
  aid 
  in 
  identifying 
  it. 
  Mr. 
  E. 
  R. 
  

   Sykes 
  kindly 
  assisted 
  me 
  in 
  the 
  differentiation 
  of 
  this 
  and 
  other 
  

   species, 
  and 
  I 
  have 
  pleasure 
  in 
  connecting 
  this 
  with 
  his 
  name.

  Slightly 
  allied 
  in 
  form, 
  but 
  not 
  in 
  texture, 
  to 
  T. 
  scaiaris, 
  Philippi, 
  

   from 
  the 
  Mediterranean, 
  this 
  pretty 
  species 
  is 
  one 
  of 
  the 
  most 
  marked 
  

   of 
  the 
  Indian 
  Tiirhonillce, 
  its 
  gradate 
  and 
  tapering 
  crystalline 
  whorls, 
  

   with 
  straight 
  smooth 
  ribs 
  and 
  equally 
  smooth 
  interstices, 
  being 
  

   noteworthy. 
  It 
  is 
  widely 
  distributed, 
  but 
  so 
  far 
  has 
  not 
  been 
  found 
  

   at 
  a 
  greater 
  depth 
  than 
  10-15 
  fathoms. 
  A 
  variety 
  occurs, 
  with 
  

   broader 
  contour, 
  wider 
  mouth, 
  and 
  fewer 
  longitudinal 
  ribs, 
  these 
  

   being 
  regularly 
  gemmulate 
  above, 
  just 
  below 
  the 
  sutures. 
  These 
  

   come 
  from 
  Bombay.

  A

   the 
  ribs 
  smoothly 
  rounded

  interstices 
  quite 
  smooth, 
  mouth 
  oblong. 
  

   Very 
  like 
  one 
  of 
  the 
  genus 
  Terehra 
  in 
  miniature. 
  It 
  appears 
  fairly 
  

   generally 
  distributed, 
  but 
  never 
  in 
  much 
  plenty 
  or 
  gregarious 
  as 
  are 
  

   icela, 
  templaris, 
  and 
  other 
  species. 
  Originally 
  described 
  from 
  Bombay
