192 Mr. A. G. Butler on new Species 2. Selaginopsis Allmani. 1876. Selaginopsis fusea, Allman, Linn. Soc. Journ, vol. xii. p. 272, .pi. xii. fig. 1, and pi. xix. figs. 1, 2. This Japanese species has similarly the hydrothecse ar-ranged in double file on each side (as opposed to the face) of the branchlets j but they are here distinctly in two lines at their bases as well as at their apices, the arrangement of cells being, as it were, that of a double Sertularia (e. g. 8. abietina) ; instead of a double Sertularella as in the last case. 3.

New-England coast (Fern?^, Alaska (O^ar^), White Sea [Meresclikoivsky) . Here we find the process of multiplication of cells carried still further, and what was in the former instances compara-ble to a double Sertularian, is here equivalent to a triplicate Sertularian, an extra pair of hydrothecse being introduced. The general aspect of the hydrophyton, as represented in fig. 15 (' Annals '), reminds us strikingly of that of S.fusca^ Johnston, in mode of ramification, in general aspect of the branchlets, and in their great slenderness at the point of at-tachment to the main stem. XXIV. — Descriptions of new Species of Heterocera from Japan. — Part II. Noctuites. By ARTHUR G. BuTLER, F.L.S., F.Z.S., &c. [Continued from p. 169.] Cosmiidse. 105. Cosmia distincta, n. sp. Primaries grey, crossed by two blackish-edged white lines, much as in C. affinis ; an abbreviated basal white lltura ; central area more or less clouded with ferruginous, with a central brown angulated belt ; external area dusky, limited internally by an irregular whitish streak; a semicircular whitish-bordered costal brownish spot, much like that of G.
