jr. HYDROIDA II 



large, aboiit twice as long as broad; they are very nearly cylindrical, or somewhat tumid in the 

 lower third, and with a very slightly expanded opening section; the basal third or fourth part 

 of the hydrotheca tapers down, after an evenly curved transition part, rapidly to the stalk. The basal 

 cavity of the hydrotheca is small, separated off from the main chamber b\- a narrow, but as a rule 

 fairly prominent ring-shaped thickening of the inner wall. The transverse section of the hydrotlieca 

 at the aperture is circular, the opening margin has from nine to thirteen low, but general!)' di- 

 stinct, rounded teeth. 



The gonothecse proceed from the stolons. They are oval to bottle-shaped, with a very short, 

 often ringed stalk, in the broad end, and a long and narrow, cylindrical distal neck. Thegonotheca 

 is smooth, often slightly asymmetrical, rarely with curved neck.

Campanularia volubilis is a circumpolar boreal species, with a very wide distribution in the 

 arctic areas; it would perhaps be more correct to describe it as an arctic-boreal species. It does not
