VII. S. (Stratospongilla) sumatrana*, Weber (Malay Archipelago). Zool. Ergebnisse einer Reise in Niederländisch Ost-Indien, i. p. 38 (1890).
Closely allied to S. indica (p. 100) but with pointed skeleton-spicules.
VIII. Ephydatia fortis, Weltner (Philippines). Arch. Naturgesch. lxi(i), p. 141 (1895).
This species is remarkable for the great development of the spines on the shaft of the gemmule-spicules.
IX. Ephydatia bogorensis*, Weber (Malay Archipelago). Zool. Ergebnisse einer Reise in Niederländisch Ost-Indien, i, p. 33 (1890).
The gemmule-spicules have rather narrow flattish disks, the edge of which is feebly but closely serrated.
X. E. blembingia*, Evans (Malay Peninsula). Q. J. Microsc. Sci. London, xliv, p. 81 (1901).
The gemmules resemble those of Dosilia plumosa but are spherical. There are no free microscleres.
XI. Tubella vesparium*, v. Martens (Borneo). Arch. Naturg. Berlin, xxxiv, p. 62 (1868).
Closely related to T. vesparioides (p. 189), but with spiny megascleres.
