Tuhularia iiidivisa has a ver>- wide distribution. Its main occurrence in the boreal seas is bound to the middle and deeper parts of the littoral region and to the upper part of the deep sea region. From the cold area we find the species but once recorded, by Grieg (1914). After the examination of his specimens I cannot confirm this record; the specimens consisting only of hydrocauli without polyps, more probably belong to another species of Tuhuhiyia inhabiting the deep sea. To judge from literature, I'libiihirid iiidivisa penetrates rather far into the shallower parts of the Arctic regions, where it is recorded even from the New .Siberia Islands (Jaderholm 1908). How- ever, as appears from what is stated above, there is a possibility tluU .some of the Arctic individuals T(j.\t-fij. I). Till- (listrilnitioii of Tiibulan'a indivisa in the Norlliern AUaiUic. are in fact to be referred to 'ruhitlaria rciialis. — The species also penetrates far towards the south. It is recorded by Fewkes (18S1) even from the Caribbean Sea, by A11 m an (1877) from between Cuba and Florida, and by I'.illard (1906) from the west coast of Africa. As Tubiilaria iiidivisa is recorded at the same time both fnmi the Iast and the West coast of North America, it must be characterized as a circumpolar or rather 'circumboreal' (Nordgaard 1912) species.
