In »Diatoms from Franz-Josef Land« P. T. Cleve mentions a 

 new Fragilaria, L. 0,011—0,016 mm., B. 0,004 mm. He names '■'^■•"''• 

 it F. lævissima as he has not seen any transverse striæ. It has been 

 found abundant in one sample fra Cape Flora«. Through the kind- 

 ness of Professor Cleve it has been possible for me to compare the 

 form found here with the original specimens of F. lævissima to which 

 it corresponds fairly well, excepting that it is slighth^ undulated. I have 

 just been able to catcli a glinise of the striæ, they are exceedingly de- 

 licate and. as is generally the case in Fragilaria, are transverseh' parallel. 



In a gathering from Hojefjæld on Bord 6, ratlier rare.
