130 G 



Canadian Arctic Expedition, 1913-1918 



The central coated portion or scapus was slightly sulcated and transversely 

 wrinkled; epidermal coating was firmly adherent, pale orange-brown, or dirt- 

 brown. 



Tentacles 16, long, slender, very mobile, variously curved, sometimes 

 spirally, and often recurved, up to 10 to 12 mm. long. They were, in life, 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 line; on alternate tentacles the V-shaped spots 

 sometimes connect with the yellow spots on the capitulum.

 from life; x about 4; b, one of the tentacles, more enlarged. By the author. 



The disk is usually 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 light 

 reddish or purplish brown; the smaller ones, situated a little higher, taper 

 down into a line below; the larger spots are usually emarginate above and 

 sometimes below. Below the reddish spots there is a band of 8 broad-oval 

 pale yellow spots, each divided medially by the pale pink line at the mesentery 

 insertion. Below these spots the capitulum is pale orange, light flesh-colour, 

 pinkish, or yellowish, like the naked basal area. 



Found first at low water of a very low tide in gravel under stones at Clarks 

 ledge and Prince's cove, Eastport, Maine, 1864 and 1868. 



A slightly different colour variety occurred at Dog island, not far from 

 Clarks ledge, at low water mark.
