  This 
  handsome 
  shell 
  is 
  of 
  an 
  unusually 
  large 
  size 
  for 
  the 
  genus 
  ; 
  it 
  

   differs 
  from 
  P. 
  crenulata, 
  Brod., 
  in 
  its 
  depressed 
  form, 
  and 
  in 
  the 
  

   position 
  of 
  the 
  apex, 
  which 
  is 
  less 
  posterior 
  and 
  much 
  less 
  elevated 
  and 
  

   curved. 
  The 
  concentric 
  lirse 
  are 
  rather 
  distant 
  towards 
  the 
  apex, 
  

   and 
  gradually 
  become 
  more 
  crowded 
  towards 
  the 
  margin. 
  I 
  have 
  no 
  

   certain 
  information 
  as 
  to 
  its 
  habitat, 
  but 
  these 
  specimens 
  were 
  recently 
  

   submitted 
  to 
  me 
  by 
  Mr. 
  H. 
  McClelland, 
  who 
  informs 
  me 
  that 
  he 
  

   received 
  them 
  with 
  a 
  lot 
  of 
  Australian 
  shells. 
  

  

  The 
  generic 
  name 
  Phenacolepas, 
  Pilsbry, 
  takes 
  the 
  place 
  of 
  Scutellina, 
  

   Gray 
  (preoccupied).
