  This 
  beautiful 
  species 
  was 
  found 
  crawling 
  on 
  a 
  

   sand 
  beach, 
  a 
  little 
  below 
  half 
  tide 
  level. 
  Like 
  its 
  congeners, 
  

   it 
  crawled 
  half 
  buried 
  in 
  the 
  sand, 
  leaving 
  a 
  furrow 
  behind.

   11 
  specimens, 
  mostly 
  rather 
  small, 
  were 
  taken 
  on 
  the 
  north 
  

   side 
  of 
  a 
  sand 
  beach, 
  Avhich, 
  except 
  at 
  high 
  water, 
  joins 
  Taboga 
  

   to 
  a 
  small 
  island 
  on 
  its 
  northeast 
  side. 
  The 
  specimens 
  had 
  

   corneous 
  opercula, 
  but 
  unfortunately 
  these 
  were 
  destroyed 
  by 
  

   the 
  rats, 
  which 
  entered 
  one 
  of 
  the 
  boxes 
  on 
  their 
  passage 
  around
