. Report of the Canadian Arctic Expedition 1913-18. Scientific expeditions. 96 G Canadian Arctic Expedition, 1913-1918 prominent usually compressed and irregular, obtuse or subcorneal tubercles; below these the surface, except near the base, is covered with rather scattered and unevenly placed firm tubercles, varying in size, and mostly transversely elongated in contraction; between these the surface is strongly transversely and longitudinally wrinkled in contraction. The tubercles in large specimens do not show any notable arrangement in vertical rows, in most cases, because of their fewness, but they are actually in rows, more evidently so in the young. The upper part, or capitulum, has a softer integument and is closely covered with numerous prominent folds or crests, having the thicker aboral lower edge lobed or verrucose, or irregularly scalloped or crenulated; less so in the young; each of these extends to and joins a tentacle, becoming thin and smooth near the margin. This capitulum can be completely contracted and infolded, together with the reversed tentacles. The tentacles are numerous, 96 or more in the larger specimens, arranged in about five cycles. They are rather stout not very long, usually blunt in expansion; the inner 12 or 24 are much the larger; those in the outer rows are not very small in the type. Two siphonogljqihs and the lip-lobes are_ large. The colour of the column, when cleaned of its dark coating, below the capitulum or coUor, in life was usually dull pale red or flesh-colour, with the exposed sum- mits of the tubercles whitish. The capitulum was brighter red and lubricous; tentacles were either dull salmon-colour or brown, sometimes Fig. 14. Actinauge rugosa Verrill. Imperfect mesenteries of the 4th and 5th cycles with the gonads partly removed, much enlarged. It was first taken by the "Bache," in 1873, in 430 fathoms, off Georges bank. It also occurred off Casco bay in 1873, in 95 fathoms. Also in the Gulf
