Stmuman Berry, Redlands, California. The cephalopoas collected by the Canadian Arctic Expedition during the years 1913 to 1916 comprise only a few fragments, principally mandibles, taken from the stomachs of two species of seals, the Bearded Seal, Erignathus barbatus (Erxteben), and the Common Rough Seal, Phoca hispida Schreber. In the light of present knowledge alone, proper identification of such material at the very least account is hazardous. But from the notes, and more especially from the figures given, it is just possible that a way will be left open for throwing a more illuminating light upon the material at some time in the future. It is hoped that the bibliographical portion of the present paper may prove of more immediate utility. It is unfortunate that knowledge of the cephalopods of the American Arctic is so incomplete, scattering, and fragmentary, as the study of this list shows. MATERIAL COLLECTED For convenience in reference, the materiat collected is listed in order accord- ing to the numbers under which it is entered in the author’s card register. [726] Numerous fragments taken from stomach of Phoca hispida Schreber, station 29f, ca. 30 fathoms, lat. 70° 13’ N., long. 140° 50’ W., a little east of Alaska-Yukon boundary, April 4, 1914. The material here entered consists of 3 fragmentary and semi-digested buccal masses of cephalopods, together with a few odd shreds of tissue and some 58 fragments of beaks, the latter consisting of half mandibles only. Not even those persisting in the buccal tissues are entire. Hach is split mesially. Evidently the median region of the mandibles is not only narrow in this species, but more than ordinarily weak. In fact, one is remimded very much of the appearance of the valves of the chiton Schizoplax after the dissolution of the median uncalcified wedge. There are other peculiarities of shape and _pro- portion (Fig. 1). On the whole the mandibles are fairly uniform in size. None a Fig. 1—The four mandibular fragments from the buccal mass of a cephalopod taken at Station 29f [726]; camera outline; the two outermost figures are internal views. 2411—2 4B Canadian Arctic Expedition, 1913-18 are very large, particuiarly in comparison with the relatively enormous size ot the buccal mass. Such structures should surely be identifiable with the passage of time—consequently it seems worth while to add figures of the four fragments aissected from the best preserved of the buccal masses. It is not, however, a glad commentary on the sufficiency of our knowledge regarding animals possessing such importance in the economy of the sea as these, that without more complete specimens or a better base of attack than is afforded by the literature, one dares not risk a guess at even the genus or family of cephalopods represented by the fragments. [727] 1 mandible from stomach of Phoca hispida Schreber, station 29f, about 30 fathoms, lat. 70°13’ N., long. 140° 50’ W., a little east of Alaska-Yukon boundary, April 4, 1914. A single dorsal mandible from the same stomach as the specimens entered as No. 726 is larger than the others, altogether differently shapea, and entire. Its cutting edge is sharp ana strongly curved, as in many decapods (Fig. 2). It clearly represents a quite different species. st 5mm. Fig. 2.—Mandible of cephalopod fromjStation 29f [727], camera outline. {j728]] 1 mandible from stomach of Erignathus barbatus (Erxleben), Station 42u, *Bernard harbour, Dolphin and Union strait, Northwest Territories, October 22, 1915. This is a singie dorsai: mandible somewhat resembling No. 727, but with the cutting edge appreciably shorter and stouter (Fig. 3). This specimen, which is preserved dry, is very likely representative of a third species. Fig. 3.—Mandible of cephalopod from Station 42u [728], camera outline, same scale as Fig. 2. In the diary of Captain Robert A. Bartlett, Report of the Department of the Naval Service for the Fiscal Year ending March 31, 1915, Ottawa, p. 35, there is an entry under Nov. 21st, (1913): “10 a.m. Sounding, 36 fathoms. Dredge to-day secured an octopus..... Lat. 72° 56’— Long. 163° 54’/W. at 5 p.m.” All the specimens secured by Mr. James Murray, marine biologist and the scientific staff of the Karluk during the drift northwest of Alaska in 1913 were lost with the ship north of Herald island, on January 11, 1914. Cephalopoda and Pteropoda BO BIBLIOGRAPHY It has been suggested that a bibliography for the Cephalopoda of the American Arctic would be found useful in connection with other bibliographies appearing in this series of papers. Defining the American quadrant as those Arctic waters lying between Davis and Bering straits, with possibly the 60th parallel as an arbitrary southern boundary, the following list of titles has been compiled as a contribution to this end. It is thought to be complete, at least to the point of serviceability, if unfortunateiy not to that of perfection. No attempt is here made to correct the synonymy quoted. A few titles incruded have not been available for consultation and are consequently quoted from the citations of other authors. Such are enclosed in brackets. Datu, W. H. 1884.

The Pteropoda Collected by the Canadian Arctic Expedition 1913-18, with description of a New Species from the North Pacific By Wituram Heautey Datu! Honorary Curator of Mollusks, United States National Museum. A small collection of Pteropoda was referred to me by the Arctic Publications Committee for a request for a report upon them. They consisted mainly of material collected by Mr. Frits Johansen, biologist with the Canadian Arctic Expedition, with a few Opisthobranchs and other specimens added from other northern Canadian localities. A peculiarity of the expedition series is the absence in great measure of aduJt specimens, nearly all the specimens of Clione and all the specimens of Sptiratella (Limacina of authors), were young, especially the latter; although Mr. Johansen frequently mentions its presence, not a single adult specimen is contained in the series. As most of the specimens were obtained near shore, it may indicate that it is the habit of the young to avoid the open sea until mature. Clione borealis Phipps. Station 6a, b.2.

Jan. 4, 1914. Camden bay, inside Collinson ae shallow water under four feet of ice; water temperature 28°.5 F. (F. The following data are derived from Mr. Johansen’s notes:— One adult Clione was 30 mm. long, the spread of the flippers 20 mm. wnen alive. The muscles of the tail were clearly visible through the trans- parent body. The purplish tint of the tail extended with decreasing in- tensity forward for about 5mm. The oral tentacles were aeep rose purple; the oesophagus rose colour, as also the edge of the body around the base of the parapodia; the intestinal mass was blackish-brown. The rest of the body was pale and translucent. The protruded oral tentacles were about 3mm. long, the hook bearing captacula when fully extendea appeared longer. When swimming, the parapodia were bent toward the ventral side, returning to a nearly horizontal position, and repeating. The anima! came up with the water in a hole cut through the ice and was caught swimming just below the surface film of new ice. Placed in a bottle of sea water which began to freeze, the animal became immobile among the ice particles. Only after arrival at camp when the ice began melting did it begin to move again. The tail is much used by the animal as a kind of rudder when changing direction of movement. When moving up or down the tail is recurved dorsally or sometimes ventrally. At times the animal would revolve in one place with the tail curved against the side of the body and the fins continually moving. When swimming horizontally it always tried to keep the ventral sice downward. When at rest it remained in a vertical position, head downward, or sank upon its ventral side to the bottom of the container. The resting periods were always shorter than those of activity. The fins if brought into contact with ice or the glass of the container, or when the animal is moribund, are folded up and held close to the body. They are subject to extreme contraction when placed in a preservative. In the warmth of the laboratory the movemeats decreased and the animal became sluggish, but if the container was placed in a colder situation activity revivea. From time to time the animal exuded mucus which seemed to embarrass its movements. On January 5, the container was put in a cool place and the water congealed during the night. When thawed the Pteropod was still alive, though less active and this was con- tinued for a week. January 12, it died, having been kept for eight days without renewal of water or tood. Station 377. Inner harbour at Eecrnard harbour, Dolphin and Union strait, Oct. 16, 1914. Under four inches of ice in about seven fect of water at a temperature of 30°.1 F. One adult Clione. (F.J.) Station 48a. Off Cockburn point, Dolphin and Union strait, September 13, 1915. Water temperature 32° I. about fifty fathoms deep. One Clione obtained. (F.J.) In view of the fact that so many good dissections have been published of this species, and that nearly all the specimens were immature and not in the best condition, it is not thought worth while to attempt anatomical work upon them. It may be noted that young are more deeply tinted than the adults and one specimen of which Mr. Johansen has made a rough coloured sketch is quite noticeably red, while others are less so. Cephalopoda and Pteropoda 11B Spiratella pacifica Dall? This genus is more generally known by the name of Limacina. The minute young specimens in the collection, perhaps from being preserved with formalin, have lost their shelly matter, and it is impossible to say whether they belong to the Pacific type or to the better known and much more common Atlantic species S. helicina Phipps.

Water temperature 50°.7 to 51°.3 F. One Spiratella with many young Clione, from at or near the surface. (F.J.) Station 13a, f. Latitude 54° 30’ N., longitude 159° 42’ W., July 1, 1913. Water temperature 47°.5 to 48°.1 F. Many Spiratella at or near the surface. (F.J.) Station 15a, f. Latitude 55° 22’ N., longitude 165° 45’ W., July 3, 1913. Noon to3 p.m. Many Spiratella. (F.J.) Station 20a. Grantley harbour, Port Clarence, Alaska, July 30, 1913. Several Spiratella from the surface. (F.J.) Station 40d. Off Bernard harbour, Dolphin and Union strait, June 8, 1915. Depth of water nine fathoms, temperature 32° F. Six vertical hauls through a hole in the ice to five fathoms depth, produced several veliger larvae of Spiratella. (F.J.) Station 46k. Off west end of Chantry isiand, in Dolphin and Union strait, June 10, 1916. Depth of water about eight fathoms, the temperature 32° F. A verticai hau: through four feet of ice to depth of five fathoms produced several veliger larvae of Spiratella. (F.J.). SPECIMENS FROM OTHER SOURCES Clione borealis Phipps. 1. Half digested young from the stomach of Myotocephalus grénlandicus, Nain, Labrador; coilected by Owen Bryant, 1908. 2. Port Burwell and Wakeham Bay Ungava, Neptune Expedition; collected by A.

Victoria Memorial Museum, Mollusks, No. 3177; cotype, presented to United States National Museum. 2. West side of Vancouver island, Ucluelet, British Columbia at low tide, C. H. Young and W. Spreadborough, May, 1919. Cotype, Victoria Memorial Museum, Ottawa, Cat. Mollusks, No. 3176. (Fig. 4) .1 1Drawn from alcoholic specimen, by Claude E. Johnson, artist of Biological Division, Victoria Memorial Museum. The lack of lateral symmetry is probably due to contraction in the preservative medium. 128 Canadian Arctic Expedition, 1913-18 Both the North Atlantic, Asiatic, and North Pacific species of Gastropteron are of a reddish colour sprinkled densely with darker red dots. The present form is of a uniform dusky slate colour and of a smaller size than the Pacific species described by Bergh. It is an interesting addition to the sparse list of known species. The spread of the parapodia totals 10 to 15mm., the length of the body 8 to 11 mm. (in spirits), in the living state it was probably larger. The anterior shield is about one-third the whole length of the body. Like G. pacificum, it lacks a posterior flagellum on the mantle. Tig. 4.—Gastropteron (pacificum Bergh var.?) cinereum Dall, new species. Left, dorsal aspect; right, ventral, X 4. Upper outline figure, natural size. Eggs of fish? Station 7a, b. Latitude 55° 42’ N., longitude 136° 20’ W., June 25, 1918. Eggs, probably of fish, were found floating on the surface. (F.J.) Young of Sipunculoid worm? Station 57. 1 fathom in marine plankton, off Cape Smyth, near Point Barrow, Alaska. This puzzled our experts, but is left without positive determination, being badly contracted by the preservative.
