Very little, next to nothing, has been published hitherto regarding 

 the occurrence of Alcyonarians at the eastern and north-eastern 

 coasts of Greenland. In 1874 Moebius mentioned Briareum grandiflo- 

 rum Sars as taken by the second German North-Polar-Expedition 1869 

 ^70 (Die zweite Deutsche Nordpolarfahrt etc. Vol. II, p. 260); this 

 statement, however, turns out to be wrong, the form in question being 

 an Eanephthya (see below under E. glomerata). In 1904 I made known 

 three different localities where UmbeUiila encrinus (L.) had been capt- 

 ured (Pennatulida Ingolf-Exped. p. 86 — 87). Nothing more is to be 

 found in the literature. The occurrence, however, at Eastern Green- 

 land of one or more of the widely distributed arctic species of the 

 genus Eunephthya might at least seem extremely probable; and in 

 fact specimens representing four species of this genus were several 

 years ago handed over to the Zoological Museum of Copenhagen 

 from Capt. Ryder's Expedition with the "Hekla" in 1891 — 92 and 

 the Carlsbergfond-Expedition with the "Antarctic" in 1900. Be- 

 sides, a single specimen of a Virgularia has been taken on the latter 

 expedition, a fact unknown to me, when I worked out my report of 

 the northern Pennatulida quoted above. 



As the somewhat scanty material of the Danmark Expedition 

 only contains four out of the six species of Alcyonarians already 

 brought back by the previous expeditions mentioned, and as no 

 account of this material has ever appeared, I take the opportunity 

 now to enumerate in the following lines all the species hitherto 

 found at Eastern Greenland, and the localities where they have been 

 caught.
