Description Carapace subrectangular, elongate in side view, valves heavy; dorsal and ventral margins straight to slightly sinuous, diverging anteriorly; anterior extremity obliquely rounded, rimmed, denticulate; posterior end truncate, with several short, blunt spines near ventral angle; surface covered with minor heavy, rounded, rather high ridges; median muscle node well-developed just in front of center; two irregular ridges extend forward from node, merge with anterior surface before reaching anterior rim; ventrolateral ridge conspicuous, winglike; another ridge, beginning just anterior to middle below dorsal margin, extends upward and along dorsolateral edge to point below posterior dorsal angle, flares outward producing blunt projection, turns inward to margin and thence extends around posterior, ventral and anterior margins; well-developed cardinal tubercle present at anterior dorsal angle; hinge of left valve with deep, rounded anterior socket and rather large, smooth, pointed postjacent tooth merging abruptly with straight, smooth dorsal edge that terminates at slightly elongate posterior socket; hinge of right valve with strongly developed, smooth anterior tooth, moderately deep postjacent socket, narrow marginal groove and faintly cusped, slightly elongated posterior tooth; marginal areas wide, with numerous, closely spaced radial pore canals; muscle scar an irregular depression.

Description Carapace subrectangular, elongate in side view, valves heavy; dorsal and ventral margins straight to slightly sinuous, diverging anteriorly; anterior extremity obliquely rounded, rimmed, denticulate; posterior end truncate, with several short, blunt spines near ventral angle; surface covered with minor heavy, rounded, rather high ridges; median muscle node well-developed just in front of center; two irregular ridges extend forward from node, merge with anterior surface before reaching anterior rim; ventrolateral ridge conspicuous, winglike; another ridge, beginning just anterior to middle below dorsal margin, extends upward and along dorsolateral edge to point below posterior dorsal angle, flares outward producing blunt projection, turns inward to margin and thence extends around posterior, ventral and anterior margins; well-developed cardinal tubercle present at anterior dorsal angle; hinge of left valve with deep, rounded anterior socket and rather large, smooth, pointed postjacent tooth merging abruptly with straight, smooth dorsal edge that terminates at slightly elongate posterior socket; hinge of right valve with strongly developed, smooth anterior tooth, moderately deep postjacent socket, narrow marginal groove and faintly cusped, slightly elongated posterior tooth; marginal areas wide, with numerous, closely spaced radial pore canals; muscle scar an irregular depression.

Remark This species is of the winged type. It may be identified by its heavy valves, general outline and the characteristic surface ridge pattern. [details]
