294 ON THE FISHES OF THE ARCTIC EXPEDITION. [Mar. 20, 
veloped as the largest, or even more so. The spines of the first 
dorsal fin are sometimes quite distinct, sometimes enveloped in loose 
skin, 

Cyclopterus spinosus. 
4, Lrparis FaBRicil, Kroyer. 
Previously known from Spitzbergen, Greenland, Fort Leopold ; 
is represented in the present collection by a specimen from Discovery 
Bay, and another from Franklin-Pierce Bay. 
5. GyMNELIS viripis, Fabr. 
One specimen, obtained in lat. 81° 52'; it is only 5 inches long, 
and belongs to a highly coloured variety, being brown with nume- 
rous white spots, and having four black ocelli on the dorsal fin. 
6. Gapus FaBrRici, Rich. 
Widely distributed in the arctic regions of the western hemisphere. 
One specimen, obtained off Cape Hayes, Grinnell Land. 
7. SALMO ARCTURUS, sp. n. (Plate XXXII.) 
The northernmost Salmonoid known at present. 
This Charr cannot be identified with any of the other races of 
this division of Salmo; it comes nearest to the Charr of Killin (In- 
verness-shire), but differs from it in having a more slender body, rather 
smaller scales, shorter fins, and a less number of pyloric appendages. 
Body rather elongate ; head small, two ninths or nearly one fifth 
of the total length (without caudal), scarcely more than one half 
of the distance between the snout and the vertical from the origin of 
the dorsal fin. The snout is remarkably obtuse; the maxillary 
varies in length: in males of the same size it sometimes reaches 
scarcely to, sometimes a little behind, the hind margin of the orbit ; 
in the female it is smaller and shorter. Teeth small; vomerine teeth 
limited to the anterior extremity of the bone; a band of villiform 
teeth along the middle of the hyoid bone. Preeoperculum with a 
distinct lower limb ; suboperculum about twice as long as deep ; pec- 
toral but little shorter than the head, exceeding in length one half 
of the distance of its root from the ventral. Ventral terminating at 
a considerable distance from the vent. D. 13, the longest ray as 
long as the head (without snout), A.12. Caudal moderately ex- 
cised, its middle rays half the length of the outer ones. Scales mi- 
nute. Branchiostegals 11. 
Upper parts of a dull brownish green, passing on the sides into 
the silvery or reddish colour of the lower parts. Dorsal and caudal
