  fall

  three 
  very 
  well-marked

  Cape._ 
  The 
  radula 
  of 
  the 
  species 
  comprised 
  in 
  Group 
  1 
  are 
  singularly 
  

   alike 
  in 
  the 
  shape 
  of 
  their 
  teeth, 
  both 
  rhachidian 
  and 
  lateral, 
  while 
  

   those 
  of 
  the 
  species 
  falling 
  under 
  (2) 
  and 
  (3) 
  manifest 
  considerable 
  

   individual 
  differences.
