  are 
  dirty 
  whitish 
  stained 
  with 
  purplish 
  brown, 
  but 
  not 
  of 
  so 
  dark 
  

   a 
  tint 
  as 
  V. 
  ovata. 
  

  

  In 
  his 
  account 
  of 
  V. 
  spongiarum, 
  Lamarck 
  questioned 
  the 
  identity 
  

   of 
  that 
  species 
  with 
  the 
  Mya 
  vulsella 
  minor 
  of 
  Chemnitz 
  (= 
  F. 
  minor, 
  

   Bolten), 
  but 
  I 
  am 
  inclined 
  to 
  agree 
  with 
  Dunker 
  in 
  considering 
  them 
  

   the 
  same. 
  Still, 
  there 
  is 
  some 
  uncertainty. 
  Chemnitz 
  makes 
  no 
  

   reference 
  to 
  radiating 
  lineation, 
  and 
  his 
  description 
  " 
  schmutzig 
  

   weissgelblich 
  " 
  of 
  the 
  colour 
  and 
  his 
  figures 
  also 
  apply 
  to 
  the 
  present 
  

   species. 
  His 
  specimens 
  were 
  said 
  to 
  have 
  come 
  from 
  the 
  Eed 
  Sea, 
  and 
  

   if 
  such 
  were 
  really 
  the 
  case, 
  it 
  then 
  seems 
  probable 
  that 
  they 
  may 
  

   have 
  been 
  the 
  V. 
  attenuata 
  of 
  Keeve. 
  

  

  Messrs. 
  Pritchard 
  & 
  Gatliff 
  ^ 
  have 
  united 
  the 
  present 
  South 
  

   Australian 
  species 
  to 
  Y. 
  vulsella. 
  It 
  is, 
  however, 
  a 
  very 
  distinct 
  

   shell, 
  and 
  never 
  attains 
  the 
  size 
  of 
  V. 
  vulsella 
  {=lingulata, 
  Lamk.) 
  and 
  

   has 
  no 
  radiating 
  colour-lines.
