this genus is, that "no difference can be traced between the wall 
of the tube and that of the hydrotheca; they are in fact no more 
Separable than they are in Sertulariids or Aglaopheniids” (op. cit. 
p. 11). It is true that the axial hydrotheca-bearing tube of a 
Grammaria abietina, deprived of the peripherical tubes, has a great 
likeness to the hydrotheca- bearing stolon of a Grammaria (Filel- 
lum) serpens. Broch is undoubtedly right in placing the species 
closely to the genus Grammaria or even including it in the latter. 
On a leaf of Delesseria from the Danmark Expedition. to 
North-East Greenland I have seen a "coppinia” of this species; 
according to the flattened form of the support the coppinia has not 
the usual cylindrical shape as when it develops on a hydroid branch; 
on the alga-leaf several hydrotheca-bearing. stolons run together 
and form a meshwork on which the gonothecæ are placed closely 
together; among the latter several funnelshaped hydrothecæ are seen. 
The species is widely distributed along the coast of Green- 
land, but it was nowhere taken in abundance by the "Tjalfe” Ex- 
Pedition. Most of the specimens are found on Diphasia abietina. 
— Levinsen records the species from Frederikshaab, Store Helle- 
fiskebanke and Egedesminde; it is very abundant at North-East 
Greenland. — The "Tjalfe” has taken it on Lille Hellefiskebanke, 
Stat, 422 (sparingly on Diphasia  abietina), on Store Hellefiske- 
banke, Stat. 100 and 371 (not uncommon on Dipk. abietina), 35 
miles south-west of Egedesminde, 415—525 meters, Stat. 107 (on 
Diph. abietina), near Godhavn, Disco, Stat. 113a (rare on Sertu- 
larella gigantea), and outside Fortunebay on the south coast of Disco, 
Stat. 180 (on Grammaria abietina and Sertularella tricuspidata). 
The species has a cosmopolitan distribution.
