* ''Ebala'' J. E. Gray, 1847 * ''Bermudaclis'' Bartsch, 1947 * ''Chesapeakella'' Campbell, 1993 * ''Ebalina'' Thiele, 1929 * ''Henrya'' Bartsch, 1947
=== 2005 taxonomy === This family has no subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).
This has been changed in 2013 into two subfamilies.<ref>Warén A. (2013) Murchisonellidae: who are they, where are they and what are they doing? (Gastropoda, lowermost Heterobranchia). Vita Malacologica 11: 1-14.</ref>
