[H. 130.] The specimen upon which this new species the type of a new genus, is based consists unfortunately only of the head and arms, which have suffered denuda- tion of the integument here and there. The .suckers are, however, almost all intact, as also the filaments which spring from beside them. A description as complete as I have been able to prepare of the specimen is given below. The Head, so far as can be seen, was flattened on the dorsal side, and slightly excavated for the funnel below. The eyes are large and prominent, and occupy the whole of the lateral surface of the head. The eyelids have disappeared, but there can be little doubt that they were of the type common to the Oegojisida. A few patches of the integument remain, which are thickly covered with bright pink chromatophores. The Arms are slender, rounded, and tapering, and bear, besides the suckers, a series of long slen- der filaments which form the characteristic pecu- liarity of the genus. The first pair are about 15 mm. in length, measuring from tlie front edge of the eye. The suckers are in two rows, small and stalked, and do not show any trace of a modification into hooks. Immediately to the proximal .side of each sucker is a dull pink chro- niatophore. Close to the base of each sucker of the ventral row arises one of the filaments above menti
