   The 
  locality 
  of 
  tliis 
  species 
  was 
  not 
  known 
  to 
  Desliayes 
  or 
  lleeve, 
  

   and 
  Hidalgo 
  has 
  not 
  recorded 
  the 
  species 
  in 
  his 
  list 
  of 
  Philippine 
  

   Pelecypoda. 
  

  

  Callista 
  eoseotincta, 
  Smith, 
  Rep. 
  Challenger 
  Lamellibr.,

   When 
  describing 
  this 
  species 
  1 
  suggested 
  that 
  it 
  probably 
  attained 
  

   larger 
  dimensions 
  than 
  those 
  then 
  given. 
  In 
  a 
  series 
  of 
  specimens 
  

   in 
  the 
  present 
  collection 
  one 
  example 
  is 
  20*5 
  mm. 
  in 
  length, 
  which 
  is 
  

   only 
  3 
  mm. 
  larger 
  than 
  the 
  type. 
  I 
  am 
  now 
  inclined 
  to 
  think 
  that 
  it 
  

   does 
  not 
  become 
  much 
  larger. 
  The 
  general 
  tone 
  of 
  colour 
  is 
  rather 
  

   like 
  that 
  of 
  " 
  Dione 
  festiva 
  " 
  as 
  given 
  by 
  Reeve 
  (Conch. 
  Icon., 
  vol. 
  xiv, 
  

   Dione, 
  pi. 
  i, 
  fig. 
  2). 
  Usually 
  there 
  are 
  at 
  intervals 
  zones 
  of 
  a 
  darker 
  

   tint 
  than 
  the 
  ground 
  colour, 
  and 
  in 
  some 
  specimens 
  there 
  are 
  distinct, 
  

   more 
  or 
  less 
  interrupted 
  rays. 
  In 
  the 
  fresh 
  specimens 
  at 
  hand 
  the 
  

   interior 
  of 
  the 
  valves 
  is 
  whitish 
  round 
  the 
  margin, 
  but 
  purplish 
  

   elsewhere, 
  with 
  a 
  pale 
  ray 
  from 
  the 
  umbo 
  downwards. 
  All 
  the 
  

   specimens 
  have 
  the 
  tips 
  of 
  the 
  umbones 
  rosy 
  pink. 
  

  

  Antigona 
  (Ciroomphalus) 
  foliacea,

  fig.

   The 
  specimens 
  in 
  the 
  present 
  collection 
  belong 
  to 
  that 
  form 
  of 
  the 
  

   species 
  figured 
  by 
  Reeve 
  (Conch. 
  Icon., 
  vol. 
  xiv, 
  figs. 
  1095 
  and 
  110)
