The new variety is characterised by relatively long and 
slender skeleton needles mostly smooth, and when spinous, 
with spines only very small and sparse. Further the amphi- 
disks also have long slender shafts and disks not de ply incised. 
The figures of the bove three forms of E. m ü 11 e r i show 
clearly the above mentioned different characters. 
А figure is also given of Meyenia №3 var я of Dy- 
bowski from Niankow а form which Vejdovsky regarded as 
identical with his Forma B. The short thick amphidisks and 
conspicuously spined skeleton spicules differ markedly from the 
same spicules in var. b e h n i n g i. 
Some might regard var. behningi asa new species, 
but is should de borne in mind that E. m ü 11 e r i is very 
„formenreich“ (Vejdovsky) and Weltner point out that „Die 
Localv rietäten sind ungeheuer gross“.
