Of this species, which is common in nearly all arctic seas, a 

 great many, large colonies are to hand, especially from St. 68 a. 

 The largest colony (St. 68 a) is 24 cm. high. 



Hydrothecae and internodes are often greatly intertwined, just 

 as in H. labrosiim. — Regarding the stolonisation see p. 356 and PL 

 XXI, lig. 1. 



Gonosome: many gonothecae on the larger colonies from St. 

 63 and 68 a. 



Many other species of hydroids grow on H. luuricatnm. On one 

 not very large colony from St. 71 a are the following 8 species: 

 Corijne eximia (rr), Lafoëa friiticosa (r), Lafoëa serpens (rr), Toicho- 

 poma obliqiiiim (cc), Cuspidella procumbens (+), Cahjcella sijringa (r), 

 Sertiilarella triciispidata (cc), Campaniilaria volubilis (r). 



Hab.: SL 21, 63, 68 a, 69, 71a, 95 a. 



Depth.: 6 — ca. 100 m., most frequent at 40 — 60 m. 



Geographical distribution: Arctic: circumpolar. — North 

 Atlantic, Euro])e and America; North Sea; Northern Pacific, America.

. Some colonies of this species occur from two stations. A single 

 case of stolonisation observed (see p. 356 and PI. XXI, fig. 2). A 

 colony with легу long hydrotheca pedicels is to hand from St. 68a; 

 a peculiarly long-stalked hydrotheca is figured on PI. XXI, fig. 3. 



Gonosome: some of the larger colonies from St. 68a are 

 densely covered with female gonothecae. 



Hab: St. 68a, 71a. 



Depth: 30—60 m. 



Geographical distribution: Arctic: Greenland, Iceland, 

 Spitzbergen, White Sea. — Atlantic, Europe and North America; 

 Mediterranean. 



Not earlier known from PZast Greenland.
