Halecium groenlandicum Kramp. 
H. groenlandicum Kramp, August 1911, p. 367, PI. XXII. 
„ polytheca Linko, December 1911, p. 73, lig. 15 and p. 240. PI. I, fig. 4. 
My description of this interesting species was based upon one 
single colony from North-East Greenland; Linko described the same 
species a few months afterwards under another name, and gave a 
thorough description of it, possessing several good specimens. From 
the short Latin diagnose and the figures I have no doubt but that 
it is in faet the same species; unfortunately I am not able to read 
the long Russian description. In his Addenda (p. 240) Linko cites 
my description of H. groenlandicum , presuming its identity with the 
species described by himself and pointing out as an interesting faet 
that the species is distributed as far west as NE-Greenland. Now 
it has also been found ofif West-Greenland: on Lille Hellefiskebanke 
ofif Sukkertoppen, Stat. 419 (one colony, 8 cm, with coppinia-like 
masses of fertile, intertwined tubes on the trunk and the rhizome; 
on a Bryozoan), and off the south coast of Disco, Stat. 180 (a 
little piece of a trunk with fertile tubes). 
Thus, the species is now known from: West-Greenland, North- 
East Greenland, Barents Sea, Murman coast and White Sea.

A few colonies on a coral from Kvanefjord near Frederikshaab, 
taken with line at 570 m depth. Do ns has recently studied this 
species and demonstrated its identity with H. mirabile Schydlow¬ 
sky and H. repens Jåderholm. It was not previously known from 
West-Greenland. Thus the species is distributed (though sparingly 
oecurring) throughout the arctic waters from the Davis-Strait to the 
Kara Port.
