N. recurva, Gabb ; Pal. Cal., Vol. 2, p. 3, pi. 1, fig. 4. 



This shell belongs apparently to the more recent members of the Miocene, 

 being found near Tomales Bay, Griswold's, El Toro Rancho, and at 

 Foxin's, in Santa Barbara County. At the latter place the beds overlie 

 the bituminous shale, and appear to be almost a connecting link with the 

 Pliocene.
