6d Canadian Arctic Expedition, 1913-18 



Entalophora sp. 



Lat. 70° 24' N., long. 161° 25' W., off northern Alaska, C.A.E. Station 23, 

 18 to 20 meters., Aug. 19, 1913. 



This species, of which there are several specimens, is much smaller than 

 the preceding, the free portions of the zooecia being shorter and narrower in 

 diameter, and more conspicuously punctate. There are no ovicells, and I 

 have no idea as to its identity. 



If exact identification were possible, the occurrence of these two species 

 in arctic waters would be interesting. E. clavata (Busk) and E. deflexa have 

 been recorded for Greenland, and E. capitata Robertson for southern Alaskan 

 waters, but little is known of the arctic species, and the genus is'mostly southern 

 in distribution. 



CTENOSTOMATA 



Alcyonidium mamillatum Alder 



Off Cockburn point. Dolphin and Union strait, at 100 meters, C.A.E. 

 Station 43a, Sept. 13, 1915, a colony of a few individuals on a hydroid stem. 



Richmond gulf. East side of Hudson bay, 15"-15 fathoms, June, 1899, A. P. 

 Low, collector. Branched specimens an inch or more in height. 



These colonies had all the appearance of those growing on hydroid stems, 

 but examination proved that they were growing free and branching, with no 

 stem of any sort at the center. I believe this habit has not been recorded for 

 this species, though it is common in the genus. 



Nolella dilatata (Hincks) 



Bernard harbour, C.A.E. Station 41/, 5 meters, Aug. 1, 1915, a number of 

 small colonies on Fucus. 



CHILOSTOMATA 



Gemellaria loricata (Linn6) 



Point Barrow, Alaska, on sandspit, C.A.E. Station 24, many colonies two 

 to three inches high attached to shells, etc., Aug. 23, 1913; Dolphin and Union 

 strait, off Stapylton bay, C.A.E. Station 436, 50 to 60 meters, one colony, 

 Sept. 14, 1915; Grantley harbour. Port Clarence, Alaska, C.A.E. Station 206, 

 July 30, 1913, one good-sized colony attached to a hydroid, at 2 to 3 fathoms; 

 CoUinson point, Camden bay, C.A.E. Station 27s, Oct. 3, 1913, 3 fathoms, 

 several colonies; C.A.E. Station 23, lat. 70° 24' N., long. 161° 2.5' W., a few small 

 colonies, at 9 to 10 fathoms. 



King George sound, Hudson strait, Ungava, Diana Expedition, Sept. 9, 

 1897, 40 fathoms. 



Dendrobeania murrayana (Johnston) 



Lat. 70° 24' N., long, 161° 25' W., C.A.E. Station 23, 9 to 10 fathoms, 

 Aug. 19, 1913, one colony of the typical variety attached to a hydroid stem. 



Dendrobeania murrayana var. fruticosa (Packard) 



Dolphin and Union strait, C.A.E. Station 43a, 100 meters, 2 colonies. 

 King George sound, south side of Hudson strait, Ungava, Sept. 9, 1897, 

 40 fathoms, Diana Expedition, several colonies.
