On new Species of Heterocera from Japan. 11 we have nothing more than one sponge bearing the three names Wi/vi(lethomsonia WalUchii, Wright, = Z)o?'u?;7^ia aga-ricifornns, K.ent, = Tt'pJiisonta agaric fonnis^ Wyv. Thorns, Its spongiose nature may he further confirmed by comparing it witli my Wagnerella horealis^ to which it bears much resemblance and which is a true sponge. Witli respect to Gastrophysema scapula, it is impossible to decide definitively whether it is a Physeraarion or a Rhizopod. On the one hand, the presence of pseudopodia, which Mr. Carter has himself observed, leads us to believe in its Foraminiferous nature; on the other, its great resemblance to the other species of Gastrophysema observed by Hackel would make us think that both organisms belong to the Physemaria. In any case fresh observations upon Squamidina scopula can alone finally decide the question. EXPLANATION OF PLATE VI. [All the figures enlarged and drawn by tlie camera lucida.] Fig. 1. An adult individual of average size of Wagnerella borealis. The peduncle is a little wider above, the head regularly rounded. There are more spicules than are here represented. Fig. 2. A young individual with the head not yet round, and differing but little from the peduncle. Fig. 3. Part of the peduncle, more highly magnified, with the small kind of spicules. Fig. 4. Form sometimes pre-^ented by the ba-^al cone of the peduncle, which, however, usually has the f irm shown in fig. 1 . Fig. o. Difterent forms of the long spicules vsrhich adorn the head : a, immeasurably fine ; b, stouter, but straight ; c, long and curved ; d, shorter and curved ; e, zigzag. Fig. 6. Different forms of spicules of the second category, fusiform, shorter and stouter : «, typical ; b, curved ; c, typical, with a bubble of air (?).

Nearly allied to G. derasa, but of a greyer tint ; the mark-ings (particularly on the white costal streak of primaries) less defined ; the reniform and other discoidal spots narrower and more transverse ; the area between the oblique white stripe and the zigzag lines pale stramineous, with darker and lunated
