Shell widest along the hinge line, outline semielliptical to subquadrate; sulcus narrow and shallow; dorsal valve variably inflated, with a broad medial depression extending from the beak to the commissure; dorsal umbo located proximal to the hinge line, not extending significantly beyond the hinge line. Emended from Foerste (1909a).<\/li>\n<li>Remarks: <em>Hebertella alveata<\/em> occurs most commonly alongside <em>H. occidentalis<\/em> and <em>H. richmondensis<\/em> in the Liberty Formation, yet is easily distinguished by its biconvex profile, maximum shell width developed at the hinge line, pronounced angular to alate cardinal extremities, and a medial depression on the dorsal valve that extends to the commissure.<\/li>\n<\/ul>\n<p><em>Davis (1998) <\/em>: <\/p>\n<ul>\n<li>Sulcus in its dorsal valve runs to the anterior margin and a long ventral interarea; Richmondian strata.<\/li>\n<\/ul>\n<p><em> Walker (1982)<\/em>:<\/p>\n<ul>\n<li>I have seen the type specimens of these species.  <em>Hebertella alveata<\/em> at the U.S. National Museum (USNM 78452, 87146, and 87158, a total of seven specimens) is characterized by a distinct and broad median depression on the brachial valve extending to the anterior margin; most specimens have alate cardinal extremities.  Foerste (1909a) applied the name <em>H. alveata richmondensis<\/em> to similar forms having a less distinct median depression, narrower hingeline, and more convex brachial valve.  He found this subspecies to be dominant over typical <em>H. alveata<\/em> at some horizons in beds of the Whitewater Formation.  <em>H. alveata<\/em> occurs in the Liberty and Whitewater Formations of Ohio and Indiana.  I consider <em>H. alveata<\/em> to be a distinct species, but none of the type specimens show interiors to confirm the generic identification.<\/li>\n<\/ul>\n<p><em>Mcfarland (1931)<\/em>:<\/p>\n<ul>\n<li>A <em>H. occidentalis<\/em> with a distinct and broad median depression extending from the beak to the anterior margin of the brachial valve.  In the types the hinge line is prolonged giving acute cardinal angles.  For the associated form with rounded cardinal angles and hinge line less than greatest width of shell.  Foerst (1909, p. 224) has proposed the varietal designation <em>richmondensis<\/em>.<\/li>\n<\/ul>\n<p><em>Foerste (1909)<\/em>:<\/p>\n<ul>\n<li>In typical <em>Hebertella alveata<\/em> (this Bulletin, vol.
