Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| G. A. Cooper 1956 | Subcircular in outline, with all margins rounded ; beaks inconspicuous ; valves nearly equal in depth; anterior commissure gently uniplicate; surface costellate, costellae narrowly rounded, about 45 in number ; brachial valve with a narrow median groove ; pedicle valve with a corresponding median costella stronger than the surrounding ones, bifurcated at the front to receive a faint median costella.
Pedicle valve strongly convex in lateral profile, strongly arched in anterior profile ; beak erect, incurved moderately ; imibonal and median regions swollen flanks swollen and with steep slopes. Median part of anterior third slightly depressed to form a faint sulcus. Spondylium deep and narrow ; septum long. Interarea well developed. Brachial valve slightly less convex than the pedicle valve in lateral profile; anterior profile strongly convex ; entire valve swollen ; lateral slopes steep; median region forming a faint fold. Midline marked by a narrow depression wider than the other striae and bearing a faint costella. Cruralium shallow and wide; fulcral plates well developed; brachiophores short, crescentic in section; median septum long, elevated. Interarea moderately well developed. |
