Shell moderatel}^ convex in front, especially in the nmbonal region,and obliquely compressed behind : posterior dorsal margin abruptlyinflected. Height somewhat greater than the length, greatest lengthjust below the winged expansion of the hinge-line above : anteriormargin shallowly concave immediately under the beaks and somewhatconvex below : ventral margin roundednarrowlyin front and obliquelyas well as more broadly so behind : posterior margin obliquely convexbelow, straighter and widening outwards above. Hinge margin appar-ently ascending above, behind the beaks, in such a manner as to forma thin alate prominence or expansion whose exact outline is not knownbut whose posterior margin seems to have been obliquely truncated orsubtruncated : beaks anterior, terminal, cuived inwards and forwards.
