Hebertella vulgaris Raymond, 1906. Annals Carnegie Museum, Vol. Ill, p. 501, et seq. Not described. Hebertella vulgaris is very closely allied to H. borcalis, but has a wider shell and very much finer stria?. Young shells have a marked sinus in the brachial valve, and it was such specimens that Billings identified as Orthis perveta and Orthis gibbosa. The shells so identified by Billings are now before me. The shell does not show a punctate structure, and therefore can not belong to Dalnianella, as Orthis siibccquata, 0. perveta and 0. gibbosa Fig. 15. Hebertella vulgaris Raymond. A large specimen, showing some bifurcating striae.
