Carapace oval in lateral view with posterior margin projecting at midheight ( Fig. 3F–I). Carapace with rostrum; ventral margin of rostrum forms obtuse angle with anterior edge of valve ventral to rostrum. Central adductor muscle scar area large and contains 2 rows of oblique scars ( Fig. 3I). Surface of carapace with round pits.  Comparisons The carapace of this species is more elongate than that of  M. hollandicaand has a pointed posterior process at midheight that is absent on the latter.   Remarks  Coryell (1963:1034) incorrectly referred specimens identified as  Cypridella koninckiana Jones 1870(Carboniferous)by Koken 1896:37, text­fig. 25: figs. 10,10a) to  M. koninckiana( Bosquet 1847). Koken’s illustrated specimen has a large node on each valve that is absent on  T. koninckiana(also see illustrations of species in Jones & Kirkby 1874: pl. III: figs. 14, 16, 17).
