  Remarks. 
  — 
  There 
  are 
  two 
  specimens 
  in 
  the 
  Montagu 
  Smith 
  

   Collection 
  which 
  agree 
  well 
  with 
  the 
  figures 
  given 
  by 
  Goldfuss 
  and 
  

   Reuss, 
  but 
  since, 
  like 
  the 
  figured 
  specimens, 
  they 
  are 
  in 
  the 
  form 
  of 
  

   casts, 
  it 
  is 
  difficult 
  to 
  be 
  sure 
  of 
  their 
  identity. 
  The 
  approximate 
  

   size 
  of 
  one 
  of 
  the 
  specimens 
  is: 
  — 
  length 
  = 
  16 
  mm. 
  ; 
  height=6 
  mm. 
  

   The 
  type 
  of 
  the 
  species 
  comes 
  from 
  the 
  Aachen 
  Greensand 
  (Lower 
  

   Senonian).

  Remarks. 
  — 
  A 
  species 
  of 
  Nucula 
  is 
  represented 
  in 
  the 
  Montagu 
  

   Smith 
  Collection 
  by 
  eleven 
  specimens 
  ; 
  it 
  approaches 
  closely 
  in 
  form 
  

   d'Orbigny's 
  N. 
  Renauxiana 
  1 
  found 
  in 
  the 
  Turonian 
  of 
  Uchaux, 
  but, 
  

   unfortunately, 
  all 
  the 
  specimens 
  are 
  internal 
  casts, 
  so 
  that 
  an 
  exact 
  

   determination 
  is 
  impossible.

  from 
  the 
  

   Cenomanian 
  of

   shorter.
