In Prof. M'Coy's figures and descriptions of E. Scouleri the hinge-line is by mistake referred to the anterior extremity, and the relations of the other margins are consequently misconstrued. His figures published in 1839 are large and carefully drawn, but those of 1844, also those by Phillips and De Koninck, are not of sufficient size, nor exact enough, to serve the purposes of the naturalist.
