To quote the descriptions of the gonosome given by these two investi- gators is sufficient to show that there is strong evidence of the identity of the species. Hincks' description is as follows: " Gonothecae borne on the stems and producing free medusiform zooids. "Gonozooid.—Umbrella (at the time of liberation) globose; manubrium short, with a simple orifice; radiating canals 4; marginal tentacles of two kinds—4 in connection with the radiating canals, of which 2 only are fully developed at the time of birth, springing from nonocellated, bulbous bases, 4 intermediate, of small size, without bulbs, slightly clavate, with thread-cells only toward the ex- tremity (?); lithocysts 4, one of which is placed halfway between each pair of the larger tentacles and close to one of the smaller. "The gonotheca of Lovenella clausa is borne on a rather long-ringed pedicel, which rises from the stem a short distance below the calycle. It is elongated in form, tapering off from the truncate top.
