This genus agrees with Galvina in its dentition, which is an important point of resemblance, but diflfers so much in other ways that it can hardly be included in the same genus. The anterior corners of the foot are produced and pointed, the vent is medio-dorsal and the cerata, though they have inflated tips, are not ovate as in Galvina, but slender and bent. A few of them stand isolated near the centre of the back. The allied genus Galvina is common in the North Atlantic and G. rupium ia recorded from Greenland. 12.

One specimen from Winter Quarters, "Hole No. 11, rim," captured April 24th, 1903. It is rather stout and of a uniform yellow colour. Length 20 mm., breadth across tips of cerata 8 mm., across the back 6 mm., height 5 mm. The foot is much crinkled, but appears to have been about 4 mm. wide. It is grooved in front and produced into short, straight tentacular Pig. 28.—Galvinella antwrctica—Cbbata. The oral tentacles are short and thick, 3 mm. long and 2 mm. broad at the base. The rhinophores are longer (5 mm.), somewhat dark and thick towards the apex. Both the tentacles and rhinophores are wrinkled, but apparently not really perfoliate. The cerata (Fig. 28) have an unusual appearance owing to their standing a considerable distance from one another and pointing different ways. They are mostly bent, thick at the base and again thick at the apex, but rather slender in the middle. The arrangement appears to be as follows when one looks at the complete specimen :— Left side. Eight side. 5 5 4 5 6 fi C 6 5 5 5 4 3 Middle. 11 3 But an inspection of the facets after removing the cerata leads to the conclusion that the anterior group is a horse-shoe, or two lines inclined towards one another,.
