When these forms of the V. cuspidata group from over the world are ultimately 
compared, the precedence of nomenclature will undoubtedly be acknowledged if 
compatible with the scientifically ascertained relationship of the forms. Grunow’s 
N. halophila is a very appropriate name for the salt-loving, even-tapering forms 
of the group, but the origtnal is a very depauperate form of the Airdrie diatom 
from central Canada or of the marine Craticula hungarica Pant. from the tertiary 
deposits of central Europe. 
Pantocsek’s Surirella torquata, which is well figured, but too briefly and 
indefinitely described, approaches in some respects Boyer’s S. Baileyana, and 
was found in a marine tertiary deposit in Hungary.
