rods, crosses, and rollers with girdles. In the inner coenenchym there are crosses and 
rods of about 0.07—0.10 mm. in length. 
The canal system is similar to that in Hunephthya rosea, although there does not 
appear to exist the same regularity, this being the result of the more irregular ramifi- 
cation. The indirect canals are well developed, but there is no direct connection.

Geographical Survey. 
In the”table on pag. 86, 87 there will be found a list of localities and depths from 
this and preceding works regarding Alcyonacea with northern distribution. Their geo- 
graphical distribution extends above the arctic, boreo-arctic, boreal and boreo- 
Atlantic zones. As regards the extension of the different geographical zones I refer the 
reader to APPELLÖF (1912). 
Arctic distribution: Gersemia rubiformis, G. uvaeformis., G. clavata, G. fruticosa, 
G. mirabilis, Hunephthya glomerata, EH. flavescens, E. groenlandica, EH. spitzbergensis, Xenia 
wandeli. 
Boreo-arctic distribution: Gersemia rubiformis, G. uvaeformis, G. clavata, G. 
fruticosa, Hunephthya glomerata, E. flavescens, H. rosea, KE. florida, E. spitzbergensis, 
Anthomastus agaricus, Alcyonium digitatum. 
Boreal distribution: Gersemia clavata, G. fruticosa, Hunephthya rosea, H. spitz- 
bergensis, Anthomastus purpureus, Alcyonium digitatum, Sympodium catenatum, Clavu- 
laria arctica, C. stormi, Anthelia borealis, ÅA. fallax. 
Boreo-Atlantic distribution: Eunephthya rosea, Alceyonium digitatum, Anthomastus 
agaricus, Sympodium catenatum. 
Atlantic-Mediterranean distribution: Alcyonium digitatum. 
In the arctic zones, species and genera belonging to Nephthyidae occur mostly, in the 
boreal zones the Cornulariidae and Alcyoniidae also exist. The latter have a more limited
