[An abbreviation of the specific name crassicornis.] A collector’s name for a species of Sea Anemone, Bunodes crassicornis.
1857. Wood, Comm. Obj. Seashore, vi. Bunodes crassicornis … is much too long a title for everyday use, and so it is contracted into ‘Crass.’
1885. J. Runciman, Skippers & Shellbacks, 101. The glossy anemone is useless, but the firm, solid crass makes the best possible lure for cod.
