Telphusa africana, Alph. Milne Edwards, Nouv. Arch. du Muséum, T. V, pag. 186, pl. XI, fig. 2 and 2a. The Museum has lately received a fine series of nine specimens of various ages of this species which was shortly described by Mr. Alph. Milne Edwards after a very young individual, so that I am enabled to give a more complete description of this form. As regards its external appearance, this species very much resembles the Indian Paratelphusa tridentata Milne Edwards, so that one is almost inclined to refer it to the genus Paratelphusa.
