waters, from the North Atlantic and from the Polar Sea; and I have 

 been convinced of the impossibility of maintaining the above two 

 as distinct species. Consequently the oldest specific name, given by 

 LiNNÆUS, has to be used for the northern Umbellula. 



The occurrence of Umbelllula encrinus at Eastern Greenland has 

 previously been stated (cfr. Jungersen 1. с. 1904, p. 86); now the 

 Danmark-Expedition has added the following new locality: Off Ma- 

 roussia (76°40' N, east of Little Koldewey), 150 fathoms, mud with 

 a little gravel, "'/т 1908. The single specimen, captured with a beam- 

 trawl working for half an hour, is complete; the stalk is 420 mm. in 

 total length, its bulbous part 60 mm. long, ca. 6 mm. in diameter 

 where it is thickest, while the thinnest part of the stalk is less 

 than 1 mm. in diameter; the length of the upper "sheath formed" 

 dilatation is ca. 6 mm., that of the rhachis-club ca. 12 mm. The cluster 

 contains 9 polyps, two of which still undeveloped; the body of the 

 longest polyp measures about 12 mm, with tentacles ca. 27 mm. in 

 length. Thus this specimen is a young one; it is more slender than 

 any of the specimens described as U. encrinus in my account of the 

 Ingolf Pennatulids, and the tentacles are much longer in proportion 

 to the body of the polyps; in which respects it agrees with several 

 specimens among a large number of Umbelhilœ, captured in the 

 Umanakfjord in 1908 by the "Tjalfe". 



The East-Greenland localities formerly published are: Cape 

 Brewster (70°9' N, 22°5' W, on the southern side of the entrance 

 to Scoresby Sound), 250 fthms. ; Canning Land (71°30'N), 202 fthms. 

 (Carlsbergfond Exped. 1900); entrance of Franz Joseph Fjord 

 (73°20' N), 200—300 M. (Kolthoff, 1900). 



и. encrinus is known from the Arctic Sea and the nearest sub- 

 arctic parts of the North Atlantic, viz.: Baffin Bay and the Uma- 

 nakfjord (here in great numbers), Davis Strait; Danmark Strait; be- 

 tween East Greenland and Spitsbergen, at Spitsbergen, Jan Mayen, 

 north and north-east and east of Iceland; between the Færoes and 

 Norway; in the Færoe-channel ; east of Franz Joseph Land, and in 

 the Kara Sea. 



If the species really — as indicated by some authors (J. Stephens: 

 Alcyon, etc. of the Irish Coasts p. 21, Roule: Bull. Mus. d'Hist. 

 nat. Vol. XI, 1905, p. 416) — is distributed far south in the Atlantic 

 — to off Marocco — seems to me extremely doubtful; and the same 

 may be said regarding its occurrence in the Pacific, near the Gala- 

 pagos Islands (Studer: Bull. Mus. Comp. Zool. XXV, 1894, p. 57); 

 cfr. my remarks in Conspectus Fauna Groenlandicæ. Alcyon, etc.
