There was perfect similarity between the specimens from the 2nd 

 Fram Expedition and the colonies from Hammerfest and the North Gape. 

 Avicularia did not often occur, and ocecia still less often, the latter being 

 punctured like the frontal wall of the zooecia, and with an indication of 

 the ring of projections that are so marked in the next species. 



Fig. 1 on PL 5 in Hydr. Biol. Inv. Norw. Fj., gives the impression 

 that the mandible is rather stumpy; but this is a mistake. It is subu- 

 late. An excrescence or elevation may sometimes be seen on the front 

 of the ocecia.

This form exhibits a great similarity to Schizoporella stormi, but 

 for safety's sake I have given it name of its own. I have never seen 

 S. stormi with spines at the oral aperture; whereas they seem to occur 

 pretty regularly in bispinosa. The zooecia have the same dots upon 

 the frontal wall in both species, but there are fewer perforations in 

 bispinosa than in stormi. In the few cases in which I have seen 

 ocecia, they have had a very much more marked ring of prominences 

 (fig. 15) in bispinosa. On the ocEcia of both forms, a prominence may 

 sometimes be seen, which is somewhat pointed upwards. The avicula- 

 rium is situated below the margin of the oral aperture, a little to the
