I. List of Twenty-two Deep-Sea Radiolarians from the Banda Sea.

P. Harting (L. N. [18]) published in 1863 the description of 14 Spumellaria and 8 Nassellaria, taken in depths between 900 and 4000 fathoms, in the Banda Sea. The figures of them are, however, for the most part not complete enough. The names are the following:—

I. Spumellaria.

01. Haliomma nitidum, figs. 13, 14 = Heliodiscus?

02. Haliomma gracile, fig. 15 = Acanthosphæra?

03. Haliomma lens, fig. 16 = Stylodiscus?

04. Haliomma pyriforme, fig. 17 = Cenellipsis?

06. Haliomma polyacanthum, fig. 40 = Druppocarpus?
