  Whether 
  the 
  specific 
  name 
  dates 
  from 
  Dall 
  (C. 
  gemma) 
  or 
  Pilsbry 
  (C. 
  gemmea), 
  the 
  

   original 
  Carpenter 
  types 
  can 
  be 
  used 
  as 
  syntypcs. 
  Tlie 
  Emerton 
  drawing 
  was 
  probably 
  of 
  

   the 
  type. 
  Five 
  specimens 
  in 
  the 
  Carpenter 
  Collection 
  in 
  the 
  Redpath 
  Museum 
  are 
  on 
  the 
  

   original 
  glass 
  mounts 
  with 
  a 
  Carpenter 
  label, 
  "type 
  Monterey 
  Canfield." 
  

  

  There 
  are 
  also 
  in 
  the 
  Redpath 
  Aluseum 
  (no.

  two 
  specimens 
  labelled 
  "Chaetopleura 
  

   gemma 
  van 
  limata 
  type 
  Monterey 
  Canfield 
  (comp. 
  lanuginosus)." 
  There
