DESCRIPTION

Small (L to 25 mm), white, sometimes yellow internally, oval, longer than high, not inflated. Sculpture of many (up to 75) narrow, low, closely-spaced radial ribs crossed by regularly-spaced commarginal lamellae, forming small scales on ribs (Fig. 17C). Lunule narrowly lanceolate, not sunken and slightly asymmetrical, with RV extending into LV. Ligament short, external. LV with 2 cardinal teeth, anterior larger and bifid, posterior tiny; two posterior and two anterior lateral teeth; RV with two cardinals, anterior small, posterior larger, and usually bifurcate, with single anterior and posterior laterals. Anterior adductor scar short and detached from pallial line for about 1/2 length. Pallial line entire. Shell margin outside pallial line glossy, edge finely denticulate.

REMARKS

Codakia perobliqua Tate, 1892 and Talocodakia kennethi Iredale, 1936 are possibly conspecific with E. consettiana but further analysis of shell variation is needed to confirm this.
