    ScORPiENIDiE. Scorpcena dactyloptera (Delaroche). Station 15. 50° 15' N., 8° 1' W. 320 fathoms. Grey sand. Bottom temperature, 8'7° C. One, 285 millimetres. Sehastes marinus (L.). Station 8. 60° 18' N., 4° 43' W. 330 fathoms. Gravel and shells. Bottom temperature, l'S0 C. Two, 280 and 245 millimetres. Station 21. 58° 19' N., 8° 51' W. 191 fathoms. Sand. Bottom temperature, 9,6° C. One, 240 millimetres. CoTTimp. Cottunculus mice ops (Collett). Station 10. 00° 3' N., 0° 24' W. 49G fathoms. Gravel, sand, mud, shells and stones. Bottom temperature, — 0T°C. Ten specimens, 148 to 245 millimetres long. One of the smallest specimens, 148 millimetres long, was a female containing ripe ova, which were 4 millimetres in diameter. Collett (1905) observed ova 4\5 millimetres in diameter in a female 195 milli- metres long. The ova are evidently demersal, like those of Coitus^ and, in all probability, are similarly deposited in masses. Mr. Opie made the following note of the colours of these specimens when freshly caught : ‘ The tail was light-coloured ; anterior to this was a brown band, and in front of this another light band, including the dorsal and anal tins ; then another brown band, followed by another light band, and then a brown band extending to the operculum. In front of this another light band extended nearly to the eye. The face was spotted more distinctly in some specimens than in others ; the tip of the nose was light in most cases, but not in all ; there was a dark patch under the eye. The belly was a bluish-white ; the under side of the pectoral fin was very dark. The eye was bright bluish-green, with a bright margin.’ The specimens show considerable variation in the occipital spines or tubercles, which may be practically simple or bicornate or tri- cornate.
