GOSSLERIELLA. 



51. 



GENUS 176. GOSSLERIELLA SCHUTT, 1893 



Fig. 265 Gossleriella radiata, 



Fig. 264. Gossleriella tropica. 



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.
