Bryozoa 7d 



Dendrobeania murrayana var. quadridentata (Loven) 



Dolphin and Union strait, C.A.E Station 43&, 50 to 60 meters, Sept. 14, 

 1915, 1 colony on a pebble. 



This specimen varies from uniserial to quadriserial in different parts of 

 the colony. There are no avicularia and the zooecial characters are those 

 described for quadridentata. 



Scrupocellaria scabra (Van Beneden) 



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

 Aug. 19, 1913, numerous colonies nearly an inch in height growing on sponges, 

 pebbles and on Callopora spitzbergensis; Bernard harbour, C.A.E. Station 41/, 

 5 meters, Aug. 1, 1915, several small colonies on Fucus. 



Dorsal vibracula' are not uncommon. The large scutes mentioned by 

 Waters (Bryozoa from Franz Josef Land, p. 54) as characteristic of St. Lawrence 

 and Greenland specimens, are very noticeable, though some specimens show the 

 smaller type. 



Caberea ellisi (Fleming) 



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

 Aug. 19, 1913, one small portion of a colonj'' among Scrupocellaria scabra. 



Bicellaria ciliata (Linn6) 



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

 meters, Sept. 13, 1915, one colony with numerous ovicells. 



It was a surprise to find this species in the collections, as it is commonly 

 supposed to be more southern in its distribution. However, Nordgaard (1918, 

 p. 27) indicates that G. 0. Sars took it at Bodo, the northernmost point of 

 Norway. It is known from both sides of the North Atlantic, the Mediterranean 

 and Red seas,. South Africa and Australia. It has not been noted on the Pacific 

 side of North America, unless indeed, the Stirparia ciliata of Dr. Alice Robertson 

 (1905, p. 279, figs, 67-71) may be a variety of this species, as both her figures 

 and description lead one to suspect. 



Menipea stnitti Norman 



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

 meters, Sept. 13, 1915, one small portion of a colony with ovicells. It is a high- 

 arctic species, hitherto known from the Kara sea westward to Greenland. 



Menipea pribilofi Robertson has been recorded by the writer from the 

 Pribilof islands, Bering sea, where it was taken from the stomach of a king 

 eider (Osburn, 1921, p. 454). 



Membranipora serriilata (Busk) 



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

 meters, Sept. 13, 1915, one small portion of a colony. 



Callopora discreta (Hincks) 



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

 meters, Sept. 13, 1915, several colonies on shells. 



Callopora lineata (Linne) 



Bernard harbour, C.A.E. Station 37&, 2 to 3 fathoms, Aug. 25, 1914, one 

 colony on an alga.
