Landskrona), the Kattegat and Skager Rak, in the Limfjord, the 
North Sea, along the coasts and in the fjords of Norway,') here 
reaching its northern (and eastern) limit at Skjerstadfjord (Vest- 
fjord, ca. 67° N); further round the Ferges, at the south western 
coasts of Iceland (Faxebugt, Skage), round the British Isles 
(“it seems probable that there is no considerable extent of the 
British area which is free from it,” Hickson, 1901; cfr. also 
J. Stephens, 1909)*); probably it also occurs along part of the 
Atlantic coast of France; at any rate it is recorded by P. Fischer 
(1. ce. p. 189) as inhabiting “nos cötes occidentales sur les 
Pecten dragués au large, par 20—45 brasses” but rare, and 
from the Bay of Biscay (Roule 1896, Studer 1901 [A. com- 
pressum], Hickson 1907); here seems to be its southern limit; 
thus it does not enter the Mediterranean. It has not been 
found at the eastern and northern coasts of Iceland, nor along 
the greater part of the south coast of this island (where it 
perhaps some day may be found, while it seems most improb- 
able that it should turn up at the northern and eastern coasts 
of. Iceland; many dredgings have been made here without 
yielding a single specimen, and, besides, the coastal fauna here 
is greatly influenced by the access of cold water). From 
Greenland it is also completely absent, and the same seems to 
hold good for the eastern coasts of N. America.*) Alcyon. 
digitatum is mainly littoral or thriving in shallow waters, 
with a bottom temperature always above the freezing point, 
in depths ranging from a few fathoms to ca. 75 fathoms; it may 
however, occasionally, be found in greater depths, f. inst. at 
3) In the Hardangerfjord it penetrates to the very end of the fjord, having 
been found at Odda. (Sørfjord). 
*) On the French side of La Manche it seems to be absent; at least it 
is not mentioned in the list given by Pruvot (Arch. Zool. exp. (8), V, 1897, 
pe. 21). 
3) Verrill (Notice of rec. add. to the marine Invertebr. of the north east. 
coast of America etc. Proc. U. S. Nat. Mus. 1879, p. 199) describes an 
“Alcyonium digitatum Linné (?),“ from Clark’s Bank, east of Cape Cod, 80 
Fihms., and states: “If not identical with A. digitatum of Europe, it is at 
least very closely related, and belongs to the same section of the genus. 
A comparative study of the spicula has not yet been made.” It seems, how- 
ever, never to have been mentioned later in any of V.’s own publications, 
and it may perhaps be concluded from this fact, that his doubt, originally 
expressed by the query, proved to be well founded.
