Ale yonarian | and Madreporarian Corals in the Museum of Bergen. 33 
and from the sea off the Norwegian coast as“far South as the 
latitude of Sognefjord or Bergen, and as far West as the Færøes 
and towards the Shetland Islands. The depth is between 140 
and 600 M. (70-328 Fathoms), and the bottom temperature in all 
cases recorded above zero. In the N. Atlantic W. of the Færøes 
and S. of Iceland it has hitherto never been taken, neither 
by the *Ingolf*, nor by the “Thor“, nor by the “Michael Sars“ 
so far it seems to keep out of the dominion of Flab. ala- 
bastrum*). It therefore appears to me at least doubtful, if 
the coral described by Duncan as Fl. laciniatum really be 
identical with Fl. Mac Andrewi. Duncan's description is not 
sufficient to settle the question; and while his figures resemble 
more F. Mac Andrewi than F. Alabastrum, the localities 
(“Porcupine* 1869, St. 3 and 25, resp. W. of the Southern 
part of Ireland, 723 Fathoms, and S. of Rockall, 164 Fathoms) 
seem to point towards FI. alabastrum. At any rate Duncan's 
statement (1. c. p. 323): ,It is a common form in the Nor- 
wegian and North Atlantic Seas, and has not yet been found 
in the Mediterranean or south of the British Channel,“ true 
as it is for the latter regions, seems not as to the ,North 
Atlantic Seas“ to be fully supported by the facts and obser- 
vations at hand").

1) Nordgaards statement, 1. ce. p. 158, that Fl. Mac Andrewi (Ulocya- 
thus arcticus) has been caught on two localities in the Murman Sea by the 
austro-hungarian Northpolarexpedition, is a mistake, the animal in question 
being Zoanthus arclticus M. Sars (efr. Marenzeller: Denkschr. Ak. Wiss. 
Wien, Vol. XXXV, 1878, p. 358, 379). 
1) Perhaps the only unbroken (small) specimen from the ,Porcupine*, 
which evidently is that figured by Duncan, was caught in the comparatively 
shallow waters S. of Rockall (St. 25, 164 Fathoms). In that case Duncan's 
name Fl. laciniatum might cover Fl. Mac Andrewi as well as Fl. alabastrum, 
and the distribution of the first would have to be extended further West 
than stated above.
