Hemitoma is a genus of slit limpets, marine gastropod molluscs in the family Fissurellidae, the keyhole limpets and slit limpets.Bouchet, P.; Rosenberg, G. (2012). Hemitoma Swainson, 1840. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=206771 on 2013-01-16
In this genus of fissurellid, there is an inconspicuous notch at the anterior end of the shell rather than a slit. The notch is best seen in an interior view of the shell.
