Forma arctica. 
To forma arectica belongs Gersemia arctica (DAN.). KUKENTHAL (1907) considers 
this form to be a species, Gersemia arctica (Gersemia in the opinion of KUKENTHAL). My 
investigation of the type specimens has afforded the following details: 
Gersemia arctica. 
The colony is low, about 1.5 cm. high, with large but few anthocodiae, which are 
placed on short, wart-like branches. The lower part of the anthocodia consists of a ca- 
lyx with strong armature. The spicules lie very close together in the anthocodiae and 
have strong thorns. In other respects they correspond both in shape and in size to the 
spicules in Gersemia fruticosa. ”The length of the spicules in the upper part of the antho- 
codiae is about 0.25 mm. and in the lower part from 0.14-—0.15 mm. 
As regards the calyx, it has in this case originated in consequence of the scanty 
development of the coenenchym in the branches, and this specimen is nothing but a 
voung or stunted specimen of Gersemia fruticosa. "The divergence in the measurement 
and shape of the spicules in this species and G. fruticosa is insignificant. The vigorous 
armature in anthocodiae, trunk, and branches is not sufficient to differentiate the 
species. Generally, in the case of younger specimens, the armature is very strong. The
