Lissarca E. A. Smith 1877

“Lissarca, subgen. nov.

Testa æquivalvis, subrhomboidalis, valde inæquilateralis (umbonibus fere terminalibus), concentric striata; linea cardinalis utrinque paucidentata, in medio lævis; margines valvarum intus dentati.

This sub-genus of Arca is distinguished from Barbatia of Gray, which is the nearest allied group, in having the shell concentrically (and not radiately) striated, with the umbones nearly terminal, and consequently it is very much more inæquilateral than is usually the case in Barbatia.”

(Smith, 1979: 185)
