. Report of the Canadian Arctic Expedition 1913-18. Scientific expeditions. 130 G Canadian Airtic Ex-pedition, 1913-1918 The central coated portion or scapus was slightly sulcated and transversely wrinkled; epidermal coating was firmly adherent, pale orange-brown, or dirt- Ijrown. Tentacles 16, long, slender, very mobile, variously curved, sometimes spirally, and often recurved, up to 10 to 12 mm. long. They were, in hfe, pale flesh-colour or yellowish, with a reddish median stripe on the outer surface distally and to near the tip; on the adoral side, near the base, there is a trans- verse spot of opaque flake-white or pale yellow, and an oval spot of the same on the outer side of the base running downward in a V-shaped marking, and extending upward as a white hne; on alternate tentacles the V-shaped spots sometimes connect with the yellow spots on the Fig. 17. Edwardsia elegans, var. picto, Verrill. Type, view of the expanded disk and tentacles, from life; x about 4; b, one of the tentacles, more enlarged. By the author. The disk is usuallj' projected in a low cone; the mouth has 8 small labial lobes; eight lines of reddish or purplish brown run from between the labial lobes and split in front of the tentcales, so as to pass each side of a tentacle; shorter radii of the same colour run to the bases of the alternate tentacles, but often do not reach the labial lobes. Between the reddish lines there are often squarish white spots, forming a circle; or else a continuous white line. The naked capitulum, which in extension may be 35 mm. long, has eight pale depressed lines, at the insertions of the mesenteries. Just below the ten- tacle bases there is a circle of light lemon-yellow angular spots; below these there is a band of alternately larger and smaller often ill-defined spots of hght reddish or ptu-plish brown; the smaller ones, situated a little higher, taper down into a line below; the larger spots are usually emarginate above and sometimes below.
