OsSBURN From the Kara sea westward to the American archipelago the marine bryozoa are perhaps as well known as in any other part of the world. Beyond these limits we have known practically nothing of the circumpolar distribution of this group. The bryozoan studies of Hincks (1884) and Robertson (1900) on the British Columbian and southern Alaskan species have indicated a simi- larity to the northern Atlantic fauna and the supposition has been general that most of the arctic bryozoa are circumpolar in distribution. The study of the bryzoan collections made by the Canadian Arctic Expe- dition, 1913-18, confirms this belief. Though this material contains only 48 species, and is therefore probably not half of the complete list that might be found in the region covered by the survey, all those obtained have previously been taken elsewhere and for the most part are well distributed in the arctic waters thus far explored. The region collected over extends from Bernard harbour, on Dolphin and Union strait, westward to Grantley harbour, on Bering strait; or from about 115 to 165 degrees west longitude. To make the series more complete for arctic America, I have included in the report the species taken farther eastward in Hudson bay and strait by the Diana and Neptune expeditions in the years 1897 and 1903-1904 respectively. The bryozoa of Greenland have been quite thoroughly studied,* and Nordgaard (1906) has reported on 77 species taken in the region of North Devon island, just west of Baffin bay. Our knowledge of the arctic bryozoa may be said to have made a partial advance some 80 degrees of longitude farther westward by the work of the Canadian Arctic Expedition, 1913-18. The collections are too small and the area covered too limited to yield more than a partial view of the distribution in this region. ; There still remains a vast region north of Siberia from Bering strait to the Kara sea, 165 degrees west longitude to 70 degrees east longitude, or nearly a third of the circumpolar area, in which the bryozoan fauna is quite unknown to us as yet. There can, however, be little doubt that the species will be found to be very similar to those of other arctic waters. Nordgaard (1917, p, 90) has indicated that ‘there seems to be some differ- ence between the arctic region of the Atlantic and that of the Pacific.” How- ever, it may be that when the unexplored regions of the Arctic ocean have been studied and the regions in which but little investigation has been made, are better known, we may come to the conclusion that there is no fundamental difference. It‘ is probably to be expected that certain species may occur in limited regions of the arctic seas, due to recent distribution from more southerly waters or for some, at present, “unknown reason, but the conditions of life in the waters about the north pole-and for an average of 20 degrees to the south- ward are so constant that a fairly uniform distribution of speries”s is to be ex- *For a digest of the wane done and a damplets list of the 186 Senoits and varieties known from Greenland, see Osburn, 1919. 3D 49889—14 4p Canadian Arctic Expedition, 1913-18 pected. One exception which Nordgaard makes is that of Callopora spitzberg- ensis, “hitherto obtained only in Spitzbergen waters,” but the writer has recently recorded this species from western Greenland (1919, p. 609) and, in the present paper, from as far west as 161 degrees, 25 minutes west longitude, northwestern Alaska. The species is therefore known to occur more than half way around the pole and is unknown only in the region north of Siberia, in which no studies have been made. In the “ Bryozoa of the Crocker Land Expedition” (1919), the writer added six species to the Greenland fauna, out of 50 reported on, which were already known to occur in arctic waters north of Europe. Iam therefore of the opinion that when our records of arctic bryozoa are fairly com- plete for the entire region around the North Pole, we will find that practically all of the true Arctic species are circumpolar in distribution. In the following report all the species taken by the Canadian Arctic Expe- dition, 1913-18, were collected by Mr. Frits Johansen; those of the Diana expedition were collected by Dr. A. P. Low and Commander Wm. Wakeham, and those of the Neptune expedition by Mr. A. Halkett. For the sake of brevity in recording, these will be referred to merely as ‘C.A.E,” “ Diana,” and aad A few other scattered records from far northern regions are included. The species are all found in the Victoria Memorial Museum, Ottawa, Canada. The localities where the specimens were collected, arranged in order from west to east are as follows:— WESTERN (Canadian Arctic Expedition, 1913-14-15) 1.

Station, August 19, 1913, dredged at 18 to 20 meters, one colony with two ovicells; also off Cockburn point, Dolphin and Union strait, C.A.E. Station 43a, 100 meters, Sept. 13, 1915, three colonies without ovicells, on worm tubes. Crisia eburnea (Linné) Lat. 70° 24’ N., long. 161° 25’ W., C.A.E. Station 23, 9 to 10 fathoms, Aug. 19, 1913, two colonies, with ovicells, on Callopora spitzbergensis. Tubulipora flabellaris (Fabricius) Lat. 70° 24’ N., long. 161° 25’ W., C.A.E. Station 23, 9 to 10 fathoms, Aug. 19, 1913, one small colony on Callopora spitzbergensis. Idomonea atlantica (Johnston) Off Cockburn point, Dolphin and Union strait, C.A.E. Station 48a, 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 37b, 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 41f, 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 Burwell, 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. 18, 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 deflera of Couch. 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. HE. clavata (Busk) and £. defleza 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 41f, 5 meters, Aug. 1, 1915, a number of small colonies on Fucus. CHILOSTOMATA Gemellaria loricata (Linné) 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 43b, 50 to 60 meters, one colony, Sept. 14, 1915; Grantley harbour, Port Clarence, Alaska, C.A.E. Station 20b, July 30, 1913, one good-sized colony attached to a hydroid, at 2 to 3 fathoms; Collinson point, Camden bay, C.A.E. Station 27s, Oct. 3, 1918, 3 fathoms, several colonies; C.A.E. Station 23, lat. 70° 24’ N., long. 161° 25’ 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. Bryozoa 7D Dendrobeania murrayana var. quadridentata (Lovén) Dolphin and Union strait, C.A.E Station 436,50 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 41f, 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 colony among Scrupocellaria scabra. Bicellaria ciliata (Linné) 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. O. Sars took it at Bodé, 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 smitti Norman Dolphin and Union strait, off Cockburn point, C.A.E. Station 48a, 100 meters, Sept. 18, 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 serrulata (Busk) Off Cockburn point, Dolphin and Union strait, C.A.E. Station 48a, 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 48a, 100 meters, Sept. 13, 1915, several colonies on shells. Callopora lineata (Linne) Bernard harbour, C.A.E. Station 37b, 2 to 3 fathoms, Aug. 25, 1914, one colony on an alga. 8D Canadian Arctic Expedition, 1918-18 Callopora craticula (Alder) Bernard harbour, C.A.E. Station 41f, 5 meters, Aug. 1, 1915, one well- developed colony on Fucus; off Cockburn point, Dolphin and Union strait, C.A.E. Station 43a, 100 meters, September 13, 1915, and Station 48¢ 20 to 30 meters, Sept. 14, 1915, several colonies on Laminaria. Callopora cymbaeformis (Hincks) Lat. 70° 24’ N., long. 161° 25’ W., C.A.E. Station 23, 9 to 10 fathoms, Aug. 19, 1913, one small colony on a hydroid stem. dean bay, Neptune expedition, 1904, on hydroid stems; south side of Hudson strait, Diana Expedition, 1897, on stem of Boltenia ovifera. Callopora nigrans (Hincks) Lat. 70° 24’ N., long. 161° 25’ W., C.A.E. Station 23, 9 to 10 fathoms, Aug. 19, 1913, one colony on a pebble. There is some variation in the position of the avicularia. Usually these are situated at the distal corners of the zooecium, but occasionally they are placed as much as one third of the way back toward the proximal end. The avicularian chambers also sometimes appear to be crowded together so closely as to form one structure, in which case the avicularian mandibles are lacking and a kenozooecium results. I am of the opinion that this is the nature of the structure which Nordgaard (1906, p. 13, Pl, 1, fig.8) interprets as an ooecium. If my interpretation is correct, the presence of rosette plates communicating with the zooecium in advance of it would require no explanation, while on Nordgaard’s interpretation this feature would be unique and difficult of explana- tion. In Nordgaard’s figure 8, that part labeled “proximal wall of the ooecium”’ should be the distal wall of the endozooecial ooecium. The internal structure of the zooecium also indicates that the ooecia are endozooecial. Callopora spitzbergensis (Bidenkap) Lat. 70° 24’ N., long. 161° 25’ W., C.A.E. Station 23, 9 to 10 fathoms, Aug. 19, 1913, numerous portions of colonies, one young colony inside of a dead Chrysodomus-shell. King George sound, Hudson strait, Ungava, Sept. 9, 1897, Diana Expe- dition, 40 fathoms, several colonies, with ooecia. Some of the specimens are bilaminate. There is much variation in the size of the avicularium and it may be turned in various directions. Some of the zooecia in specimens from both localities bear a short erect spine at each distal corner as figured by Smitt (1868, Pl. XX, fig. 35). Nordgaard (1918, p. 45) states that he has never seen the spines, and they appear to be of rare occurrence. What seems to be a variety of this occurred among the material from C.A.E. Station 23. In this one small specimen the zooecia are smaller, the avicularia are smaller, and there’ are sometimes two of them, at the distal corners of the zooecilum and faced toward each other. The ooecium and the zooecial characters are similar to those of spitzbergensis and the dorsal wall is similarly perforated. Tegella unicornis (Fleming) Bernard harbour, C.A.E.

This species in recent years, has been shifted back and forth between Porella and Smittina, by various authors, According to the most recent dis- criminating study by Canu and Bassler (1920, p. 457) its mode of calcification, as well as the presence of a lyrula and cardelles, shows it to be a Smittina.

Station 43a, 100 meters, Sept. 13, 1915. A portion of one colony on a dead shell. Canu and Bassler (1920, p. 457) point out that this species must be removed from the genus Porella on account of its mode of calcification (pleurocoyst) in spite of the absence of a lyrula. Mucronella (Escharella) indivisa (Levinsen) Off Cockburn point, Dolphin and Union strait, C.A.E.

Cheilopora sincera (Smitt) Off Cockburn point, Dolphin and Union strait, C.A.E. Station 43a, 100 meters. Three small colonies without ooecia. Cheilopora praelucida (Hincks) Off Cockburn point, Dolphin and Union strait, Station 48a, 100 meters, Sept. 13, 1915. One colony on a shell, very young, without ooecia. King George sound, Hudson strait, Ungava, Diana Expedition, Sept. 9, 1897, 40 fathoms. One colony without ooecia. The writer is of the opinion that praelucida will prove to be not more than a variety of C. sincera. There seems to be much variability in the length and breadth of the mucro. Hincks (1884, p, 27) states in his original description that praelucida has no avicularia, and again (1888, p, 225) that the processes at each side of the peristome are not really avicularia. Osburn (1912, p. 283) has shown that some of these processes may bear avicularia, while in others the avicularia are suppressed. The facts are these: some individuals and some entire colonies are devoid of avicularia, others have degenerate aviculara and still others fully developed avicularia similar to those of sincera. The peristome rises higher and the mucro is larger in typical praelucida, but these characters show considerable variation and apparently intergrade. Other zooecial characters seem to agree. As all my specimens from the present col- lection are young, I hesitate to positively merge the species. 12p Canadian Arctic Expedition, 1913-18 Schizomopora (Cellepora) surcularis (Packard) Lat. 70° 24’ N., long. 161° 25’ W., C.A.E. Station 23, 9 to 10 fathoms, August 19, 1913. One young colony, attached to a hydroid, consisted of only a few zooecia.. King George sound, Hudson strait, Ungava, Diana Expedition, Sept. 9, 1897, 40 fathoms. Several small colonies were attached to barnacles. The writer has listed the species from St. Paul island, one of the Pribilof group, in the Bering sea, where it was taken from the stomachs of the Pacific and king eiders.

APPENDIX Since the body of this report was prepared, the writer’s attention has been called to the omission of a brief reference to Bryozoa from Northern Alaska. John Murdoch, in the Report of the International Polar Expedition to Point Barrow, Alaska (Washington, 1885) mentions three species taken on that expe- dition pages (167, 168 and 170). The species listed by Murdoch are as follows: Gemellaria loricata (Linne) Washed up on the beach at Point Barrow. Flustra papyrea (Pallas) Smitt Point Franklin, 134 fathoms, and Plover bay, Siberia. This adds another species to the list for this region and if properly identified it should now be recorded as F’.. carbasea Solander. Leieschara subgracilis (D’Orbigny) Off Point Franklin. This species was not found among the collections of the Canadian Arctic Expedition. It is now placed in the genus Myrtozowm. Murdoch mentions also Membranipora sp. and Discopora sp.
