 Aug. 19, 1913, two colonies, with ovicells, on Callopora spitzbergensis.

 Aug. 19, 1913, one small colony on Callopora spitzbergensis. 



Idomonea atlantica (Johnston) 



Off Cockburn point, Dolphin and Union strait, C.A.E. Station 43a, 100 

 meters, Sept. 13, 1915, two colonies attached to a worm tube. 



Lichenopora verrucaria (Fabricius) 



Bernard harbour. Dolphin and Union strait, C.A.E. station 376, 2 to 3 

 fathoms, Aug. 25, 1914, one colony on an alga; C.A.E. Station 41c, July 28, 

 1915, 10 meters, on algae; C.A.E. Station 41/, 5 meters, Aug. 1, 1915, abundant 

 on Laminaria and less conmon on Fucus ; west of Cockburn point. Dolphin and 

 Union strait, C.A.E. Station 43c, 20 to 30 meters, Sept. 14, 1915, many colonies 

 on Laminaria. 



Neptune Expedition: Port JBurwell, Ungava, July 28, 1904; Hudson Bay, 

 1904, on hydroid stems; and North Somerset island, Aug., 1904, on beach. 



Lichenopora hispida (Fleming) 



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

 1897, 40 fathoms, one colony on a dead shell. 



Stomatopora fungia (Couch)? 



Off Cockburn point. Dolphin and Union strait, C.A.E. Station 43a, 100 

 meters, Sept. 13, 1915, several colonies, recumbent basal portions only, on shells. 

 The fasciated bases of erect portions are present, but the erect branches seem 

 all to have been lost. 



Diplosolen (Diastopora) obelium (Johnston) 



King George sound, Hudson strait, Ungava, Sept. 9, 1897, 40 fathoms, 

 Diana Expedition, two colonies, with ooecia, on a dead shell. 



Entalophora sp. 



Dolphin and Union strait, off Cockburn point, C.E.A. Station 43a, 100 

 meters, Sept. 13, 1915. 



The species of Entalophora are in such a tangle that, in the absence of 

 perfect specimens with ovicells, I decline to name the present one. There is 

 one specimen, about 15 mm. high, dichotomously divided into four branches. 

 The free portions of the zooecia are more than twice as long as the diameter 

 of the zooecium, irregularly distributed around the stem, and project in an 

 irregular manner. Two smaller specimens are also present, one of them with 

 an ovicell so broken as to be useless for purposes of identification. The species 

 may be the defiexa of Couch.
