_S. vagina._ The Razor Sheath. Pl. 31, fig. 5.

Valves equal, truncated at both ends; straight or slightly curved;
summit terminal.

_S. cultellus._ The kidney-shaped Solen.

Species a little curved lengthwise; summit not terminal.

_S. rostratus._ The violet-beaked Solen.

Species with longer and narrower valves, flatter at the extremities;
callosity at the hinge very visible; cardinal teeth or hinge nearer the
middle than the anterior side.

_S. ensis._ The Sabre Solen.

Species linear, sabre-shaped; a single compressed tooth in each valve;
olive brown at the base, and of a purple hue near the apex.

_S. siliqua._ The podlike Solen.

Species linear, straight; two teeth in one valve and one in the other;
covered with a glossy brown epidermis; striated transversely.

_S. antiquatus._ The Antiquated Solen.

Species thin, white, and almost transparent; striated concentrically;
ends rounded; hinge near the centre; a tooth in one valve locking into
two in the other; the teeth erect and projecting beyond the margin;
covered with a dark-coloured epidermis.


                        2. Panopæa. One species.

Distinguished from the Mya by the prominency of the apex and the
situation of the ligament.

Shell regular, elongated oval, gaping at the two extremities, equivalve,
inequilateral; summit but little marked, and anterodorsal; hinge very
complete, similar, formed by a conical primary tooth before a short,
compressed, ascending callosity; ligament exterior, attached to the
callosity; two muscular impressions.

_P. Aldrovandi._ The Panopæa of Aldrovandus. Pl. 5, fig. 2.

The type of this genus, transversely elongated, undulated;
concentrically wrinkled; of dark green colour, almost black.


                     3. Solecurtus. Three species.

Shell oval, elongated, equivalve, sub-equilateral, edges almost straight
and parallel; the extremities equally rounded, and as if truncated;
summits but little marked; hinge toothless, or formed by some
rudimentary primary teeth; ligament projecting, affixed to the thick
nymphal callosities; two distant, rounded muscular impressions.

                          Solecurtus radiatus.
                          S. strigilatus.
