The genus Conularia was first described by Miller about the year 1820, and afterwards more fully by Sowerby, as a “conical hollow univalve shell,” (Min. Con., vol. iii. p. 107). It had previously been figured by Ure under the name of a “curious fossil” (History of Rutherglen and E. Kilbride, p. 330). Sowerby, amongst other characters, noticed that in one of his specimens, formerly in Miller's collection, the edges or “lips” of the broader or truncated end of the shell were inflected, and nearly met in the centre (l. c. t. 260, fig. 4).
