Original Description
The second shell is about 45µm in diameter, the third about 110-120µm. The fourth shell was absent in all specimens found. Six radial spines rising from the second shell go out from the third shell. The other four spines rise from the third shell and have no connection with the second shell. All 10 spines have acute blades, are wide near the third shell but become very thin at about 60µm so they look like spikes. Pores on the third shell are rather regular, nearly of the same size, and polygonal. The bars between the pores are very narrow. Short by-spines rise from the third shell and are not always seen.

Etymology: The species is named after Vasilij Michailovich Golownin (1776-1831), Russian investigator of the southern hemisphere on the ships Kamtchatka and Diana.

Editors' Notes
The description is based on 23 specimens from Site 278 (Cores 12-15) and on some specimens from the core of "Ob" Station 256.
