An, testa superiors rotundata seu rotundate ovata^ tenuis convexa, sub-lcevigata, 

 seu variatim et irregulariter costulata; apice sub-marginalia indistincto, obtuse 

 incurvo ; margine cardinali inflexo^ intus paulo incrassato ; fovea ligamentali parva^ 

 transversa. 



A small species with the upper valve of an orbicular or roundly-ovate shape, 

 generally strongly convex, nearly smooth, (the surface being probably corroded), 

 or with irregular moderately elevated transverse, curved ribs ; the margins are very 

 thin, entire, or slightly undulating, evidently depending upon the character of the 

 surface on which the species is sessile ; the beak is indistinct, sub-marginal ; the 

 cardinal margin is somewhat inflexed, internally slightly thickened, with an indis- 

 tinct transverse ligamental groove below the beak. The lower or perforated valve 

 has not been observed. 



Locality, — ComarapoUiam, in a soft, coarse siliceous sandstone. 



Formation, — Arrialoor group.
