Washington; south to southern California; east to Utah. 



■ Sowerby states that his species is from Lao, (Laos ?) an error without doubt, as it is 

 certainly A. ivalilametensis . As the name rostrata had been used for an Anodonta by 

 Kokeil (or Rossmassler) Fischer changed Sowerby's name to laosensis.
