Description
Pallets variable in shape, but with blade always in one piece, periostracum usually thin and closely adhering to cal- careous base (in some species may extend beyond calcareous portion distally as narrow border, but never forms cap, as in Lyrodus); blade usually sheathing stalk. Siphons usually separate. Y oung, in all species examined to date, carried in brood pouch dorsal to gills. Anatomy generally similar to Lyrodus. [The genus has been divided into numerous subgenera which are probably of little value, as intergrades are constantly being found. These, however, are listed and their type species figured.)
