Diagnosis Shell broadly oval, apex at posterior margin; coiled stage limited to early juvenile, deck attached to shell at left side and posteriorly; right side of shell interior marked by deep sinus separating deck.
Remarks. The genus differs from Crepidula in having the deck attached only on the left side. Hoagland (1977) placed it in the synonymy of Crepidula. However, following the tradition of previous authors, Crepipatella is here used as a genus because the deck condition is a clear character that can be recognized in fossil forms.
