II. S. (Euspongilla) philippinensis*, Annandale (Philippines). P. U.S. Mus. xxxvi, p. 629 (1909).
Related to S. alba and still more closely to S. sceptrioides of Australia. From the former it is readily distinguished by having minutely spined megascleres, green corpuscles, slender gemmule-spicules with short spines and no free microscleres.
III. S. (? Euspongilla) yunnanensis*, Annandale (W. China). Rec. Ind. Mus. v, p. 197 (1910).
Apparently allied to S. philippinensis but with smooth skeleton-spicules and a more delicate skeleton.
IV. S. (Stratospongilla) sinensis*, Annandale (Foochow, China). P. U.S. Mus. xxxviii, p. 183 (1910).
This species and S. clementis are referred to Stratospongilla with some doubt. Their gemmules are intermediate in structure between those of that subgenus and those of Euspongilla. In S. sinensis the gemmules are packed together in groups at the base of the sponge, and their spicules are smooth, stout, and gradually pointed.
V. S. (Stratospongilla) clementis*, Annandale (Philippines). P. U.S. Mus. xxxvi, p. 631 (1909).
The gemmules are single and closely adherent at the base of the sponge. Their spicules are very slender and minutely spined.
VI. S. (? Stratospongilla) coggini*, Annandale (W. China). Rec. Ind. Mus. v, p. 198 (1910).
The gemmules apparently lack microscleres. They resemble those of S. clementis, to which the species is probably related, in other respects. The skeleton-spicules are spiny and rather stout, the species being strongly developed at the two ends.
