26 EXPEDITION TO JAPAN. 
13 rays. Caudal with pointed lobes, and deeply forked. Anal in the figure seems placed too 
far forward. Lateral line straight. Scales rather small and rounded. 
Colors. Deep indigo blue on back of head and body, shading off on under side to white. 
Eight strongly marked bars of same color as the back, and equally spaced, extending vertically 
down on sides ; the first and last ones not reaching the lateral line, while the intermediate ones 
just pass over it. A large blue spot on the lateral line just behind the opercles. Three smaller 
spots below the lateral line at unequal heights, but placed vertically under the spaces between 
the first four bars. These bars and spots are shaded around their margins. Dorsal pale blue, 
with membrane between tips of first six rays darker. Pectorals, ventrals, and anal, nearly 
colorless. Caudal pale dusky, with dark-tipped lobes. Lateral line lighter than body. 
45. OSMERUS OLIDUS? Pallas. 
SALMO, (OSMERUS) oLIDUS, Pallas, Zoog. Ross. Asiat., Vol. III, p. 391. 
PLATE X, fig. 2. 
Norrs.—F rom Hakodadi, (64 inches. Ugoi.) 
No species of smelt is described in the Fanna Japonica, and as the fish noticed in that work 
seem to have been collected around the southern shores of Japan, it is probable that it is not 
found so far south. 
Diengkitsch pronounced Medhurst’s name for the smelt, Kisgo, to be erroneous, and also said 
that Ugoi was not its true name. Ugoi, or Foogoi, means that it is not a carp, but he could 
not remember the name of the smelt. 
Many Russian travellers have noticed smelt in the Pacific, and describe two species of Osmerus 
and one of Mallotus. (Vid. Kracheninnikow, Gmelin, and Pallas, op. cit., p. 386.) Mr. Collie 
appears to have met with two species of Osmerus in Awatscha bay, according to the notes on 
page 49 of the Zoology of Beechey’s Voyage in the Blossom. Pallas seems to have supposed 
that the Osmerus Lperlanus and Spirinchus of Europe were also found in the Pacific, which M. 
Valenciennes (vol. 11, pp. 378 and 388) seems to admit, though the species can hardly have so 
wide arange. Pallas (op. cit.) describes an Osmerus olidus, as peculiar to the Pacific, which 
is not noticed or even quoted in the Hist. des Poissons. In the absence of more certain data, it 
it is assumed to be the fish herewith figured, though the species is said by Pallas rarely to 
exceed a length of four and a half inches. It is the first time that an Osmerus from the North 
Pacific has been figured. Specimens of this and of other species, if any exist, will no doubt be 
found among the collections brought home by the North Pacific Surveying Expedition. 
46. CHATOESSUS PUNCTATUS, Temm. and Schleg. 
Cuatorssus punctatus, T. and S., Faun. Jap. Pisces. 240, pl. CIX., fig. 1. 
Norrs.—Yedo Bay, April, 1854, Konoshiro, (8 inches.) 
The drawing corresponds exactly with the quoted figure. The name given to the Herring 
in Medhurst’s vocabulary is the same as the one marked by a Japanese on the figure. Stro or 
Shiro signifies ‘‘ white.”’
