THE CAMPANULAKID^ AND THE BONNEVIELLIDiE. 31 



A specimen from off the Alaska coast (station 2850) is considerably larger than the one 

 described, the whorls of pedicels are more distant and there are sometimes as many as nine 

 pedicels in a whorl. This probably represents Campanularia fascia Torrey.^ I find no dif- 

 ference, however, that can be regarded as specific. Another specimen (station 2858) from 

 near Sitka, Alaska, depth 230 fathoms, is more bushy and dendritic in its habit, the branches 

 often being more or less contorted like those of an oak tree. The gonangia are more slender, 

 especially in the distal neck. Here again there is nothing that seems to justify a separation 

 from 0. verticillata. It is doubtless the form described as C. circula Clark.^ 



Distribution. — In American waters. Labrador (Packard); Nova Scotia (Nutting); New 

 England coast (Verrill and Nutting) ; Bering Sea (Jaderholm) ; Alaska (Clark, Nutting) ; Puget 

 Sound (Nutting); Californian coast (Torrey, Nutting). Albatross station 2850, lat. 64° 52' N.; 

 long. 159° 46' W., 21 fathoms. Albatross station 2858, lat. 58° 17' N.; long. 148° 36' W., 238 

 fathoms. Kodiak Harbor (Harriman Exped.). Numerous stations along the Alaskan Coast 

 (Nutting, manuscript). 



General distribution.^ — Sweden (Segerstedt), Norway (Bonnevie, Broch), North Sea 

 (Broch) ; Iceland (Saemondsson) ; Greenland (Levinsen, Hartlaub) ; Spitzbergen (Marktanner- 

 Turneretscher) ; Murman Sea (Jaderholm) ; White Sea (Schydlowsky) ; Barents Sea (Thompson) ; 

 Polar Sea (Bergh) ; Biitish Islands (Hincks and others) ; Helgoland (Hartlaub) ; Denmark 

 (Levinsen); France (Billard); McMurdo Bay, Antarctic (Hickson and Gravely). 



Bathymetric distribution. — Shallow water down to 600 meters off the Norwegian coast 

 (Bonnevie), 230 fathoms off the Atlantic coast (Nutting). 



This species as above indicated has a very extensive distribution throughout the Northern 

 Hemisphere except in Asiatic waters. The extension of the species into the Antarctic regions 

 rests on the form described as C. verticillata var. grandis, Hickson and Gravely. The author 

 has seen one specimen from Japanese waters that is apparently of this species and if this is 

 true the distribution should be extended to Asiatic waters.

' The author desires here to state that he has made extensive use of the excellent monograph of Jaderholm, "North- 

 ern and Arctic Invertebrates, Hydroiden," 1909, in working out the distribution of the Oampanularid*. He has 

 also availed himself largely of the data given in Broch 's fine monograph "Die Hydroiden der Arktischen Meere," 1909.
