Not at all unlike the dysera of Chemnitz, but the concentric 
ribs are in that species distant and membranaceous, whilst in ours 
they are thick, obtuse, and rather crowded.

So extremely like the young of fasciata as with difficulty to 
be distinguished. Its form, however, is proportionably broader 
between the lateral extremities, the valves are much more com¬ 
pressed, and the interstitial spaces decidedly broader. The hinder 
terminations of the lamellar ribs, which project beyond the escut¬ 
cheon in compressed tubercules, do not appear to become obsolete 
by age, as in fasciata.
