Show 476 ON T H E FISHES O F T H E LATE ARCTIC EXPEDITION. [June 5, of which were not contained in Capt. Feilden's collection, as seen from the following list:- I. Marine Species, collected in Franklin-Pierce Bay, August 11, 1875. 1. ICELUS HAMATUS, Kroy. 2. TRIGLOPS PINGELII, Reinh. No specimens of this fish were previously in the national collection. It appears to be much scarcer than the preceding. Externally the ventral fin appears to be composed of three rays ; but on dissection four long rays and one rudimentary one are found. 3. CYCLOPTERUS SPINOSUS, adult1. Ova contained in the same bottle as these specimens are of the size of large hemp-seed. 4. LIPARIS FABRICII, Kroy. 5. GYMNELIS VIRIDIS, Fabr. 6. GADUS FABRICII, Rich. II. Freshwater Species obtained from Lakes in Discovery Bay. 1. SALMO ALIPES, Rich. Of this species two examples were obtained, about 15 inches long; it is a well-marked species of Charr, characterized by the deep radiating and concentric striation of the gill-covers. The typical specimens were obtained in Boothia Felix ; so that this Charr has an unsually wide range. Colour silvery, with scarcely any pinkish tinge. Caec. pyl. 41. 2. SALMO NARESII, n. sp. The body much elongate, its greatest depth being one fifth, or even one sixth, of the total length, without caudal. The length of the head is one fourth or two ninths of the same length, and nearly one half of the distance between the snout and the vertical from the origin of the dorsal fin. The snout is obtuse, the forehead flat; and the maxillary extends in the male to the vertical from the hind margin of the orbit, but in the female it is somewhat shorter. Teeth 1 Cyclopterus lumpus we did not receive either from Capt. Feilden or Mr. Hart. It does not seem to extend so far northwards as C. spinosus. M r. Horner, the Naturalist of the ' Pandora,' to w h o m we are indebted for several valuable additions to our series of Arctic animals, collected very young examples in lat. 64° 53' and long. 53° 20' W . attached to Fucus vesicula. H e remarks that these little fishes are very similar in form and colour to the air-vessels of that plant. |
