Shell oblong, equivalve, inequilateral; valves gaping at both ends; ligament external; the outline of the pallial margin can be slightly concave.
 

« Shell less gaping (than in Solecurtus), with no rays or, when they exist, not wavy; hinge variable, with sometimes three to four teeth on a valve. » – C. A. Récluz: “Mélanges malacologiques”, Actes de la Société Linnéenne de Bordeaux vol.XXVII, Bordeaux 1869, p.67.
 

« Species [of Solen] slightly curved in their length; summit not placed at extremity [like in the genus Solen]. » – H.-M. D. de Blainville: Manuel de malacologie et de conchyliologie vol.I, Paris 1825, p.570. Ch. Des Moulins notes: « Pallial impression deeply indented, that is to say that the sinus advances at least as far as the beginning of the teeth of the hinge, and sometimes even beyond the vertical line which would run from the summits down to the ventral edge » (“Notice sur la répartition des espèces dans les genres Solen, Solécurte, Sanguinolaire et Solételline de M. de Blainville”, Actes de la Société Linnéenne de Bordeaux vol.V, Bordeaux 1832, p.96).
