The Calanticidae includes 10 extant and five extinct genera (Newman 1996, Jones 1998 , Young 2003 ), the most generalized of which, Scillaelepas , was known from the fossil record ( Seguenza, 1876 ) before a living representative was discovered in the deep-sea ( Aurivillius, 1894 ). As will be seen below, the calanticid reported upon herein belongs to Calantica , a genus that has diverged little from the stem form.
