  The recent species of this genus are not numerous; the few fossil species occur in the tertiary strata. C. carinata is found in Calc-grossier and London Clay. In general form this resembles Cassis, but is at once distinguished by the canal, which does not turn abruptly back, but is slightly curved upwards.

The genus, species and common name (if available) for each example are given. In addition, whether the genetic exchange was characterized as horizontal transfer (as, for example, is the case in transfers between cyanobacteria and bacteriophages) or introgressive hybridization (i.e., involving sexual reproduction and backcrossing; 1) is by: Lindberg, D.R.

Macoma tenta are one of two species of macoma clams that can be found in the Chesapeake Bay on the eastern shore of the United States in Maryland and Virginia.

The macoma tenta like their cousin in the Chesapeake, the Macoma. Species: balthica. Taxonomic Notes: Macoma balthica was formerly M. inconspicua and based on recent genetic work (Vainola, ) it has been suggested that temperate individuals on the Atlantic coast of North America (Virginia north to the Bay of Fundy) should be treated as the separate species M.
