MEGALOPA, Leach. The situation of this curious genus, which is figured in Dr. Leach’s Malacostraca Brit. (tab. 25.), is still doubtful. It however decidedly belongs to the Macroura, as Dr. L. has discovered to be the case, since the publication of the first volume of the Supp. to Encyel. Brit. Legion Il. EDRIOPHTHALMA. The Bfalacostraca ‘Edriophthalma, or at least a greater part of them, were placed amongst the Macroura by Latreille, who considered them as forming a particular family of that order. Sectjon I.
