Ciliata. 
Cyttarocylis denticulata (Exs.). Branpr (Bibl. Zool. 1896) has some years ago split 
the Tintinnus denticulatus of EHRENBERG in several new species, which, however, seem to 
me to be mere varieties. But as it is of a certain importance for hydrography to distin- 
guish also races I have tried to keep the forms separate. Around Spitzbergen was found, 
besides, a new variety obtusa (Aurivituvs), which differs from var. giyantea by the apical 
end being rounded.
