GOSSLERIELLA. 51.
GENUS 176. GOSSLERIELLA SCHUTT, 1893
Fig. 264. Gossleriella tropica.
Fig. 265 Gossleriella radiata,
Frustule disciform ; valve orbicular, having a marginal crown of
gibbous prominences, bearing straight elongated robust spines, with
smaller spines scattered between them.
This genus which belongs to the Xanthwpyxidece, according to De Toni,
has a vague resemblance to Coscinodiscus Sol. I should not like to affirm
decisively that it is a diatom.
Only a single form, G. tropica Schutt (fig. 264), the hairs of which are
of the same length but of an unequal thickness, and G. radiata Schutt
(fig. 264), the hairs of which are of a very unequal length.
