Fig. LXII. The distribution of .â iS/e/tnaria nbietina in the Northern Atlantic. In the hatched regions a common occurrence is reported. peculiar diaphragm of Abietinaria abietina^ as pointed out by Levinsen (1893 p. 56). Generally speak- ing, the stucture of the colonies will obviate any doubt when deahng with the last-named species, but this is not always the case. Occasionally, Abirlinaria abii/iiia may assume a finer struct- ure (of. Brocli 1908) and it was from observation of such doubtful colonies that I was led to combine the two species under a common name. In such dwarf colonies, however, identity ma}' easih- be deter- mined by examination of the diaphragm, which in Abiefinaria abietiiia is typically bilateral, whereas in Abietinaria Jiliaila the development is almost entireh- radially symmetrical. Abietinaria abietina is a circuin]wlar boreal species, capable of penetrating far into the arctic area, albeit its occurrence there is more sporadic. It can also move far to the south, and is found in the Mediterranean and at Madeira. It belongs really to the littoral region, but mav exceptionally.
