ZOOLOGY. 
Of the present species we have identified seven specimens now in the Smitlisonian collection. 
Several of these are perfect skins, obtained by the writer from Paget Sound; others are simply 
the heads of individuals received from different sources. The figure given by Richardson in 
the latter part of his work owf-slies, in the Fauna Boreali Americana, is an excellent representa- 
tion of the adult male of this species.

Si'. Ch. — Male: Dorsal profile much more arched than in S. Sconleri, Eicii. After entering fresh water, anadipofe linmp 
becomes strikingly apparent, its greatest prominence being nearly oppoi-ite a point midway on a line drawn fiom the eye to 
the anterior margin of the base of the dorsal fin; intermaxillary projtction curved strongly downwards as in 5 ScouUri ; 
jaws long, as in latter, the the lower terminated by a dilated knob, (as in several other species of the genus,) which is armed 
with four or five strong, sharp teeth on each side ; labials and limbs of the lower jaw closely set with very fine, sharp teeth' 
finer and more numerous than those of the S. Scouhri ; vomerine and palatine teeth much larger than those of the labials ; 
those on the vomer disposed in a single row on its anterior portion ; tail rather str-ongly lunated, and profusely d<jtted with 
elongated oval dark spots; the other fins usually unspotted, alipoie rather elongated ; scales much smaller than those of the 
S. Scouleri, those of the back are much smaller than those below the lateral line. 
Hub — The Northern Pacific coasts of Asiatic Piussia and America ; Puget Sound. 
The colors of this, like those of other species, vary much after the fish enters fri'sh water. 
Those caught in salt water are more or less silvery. After entering fresh rivers the color of 
the upper parts become of a dirty grayish yellow ; below white, blotched with yellow. These 
colors, however, vary considerably in different individuals. 
Dr Kennerly, who obtained a specimen of the present species at Anaimo, Vancouver's 
Island, September 22, 1857, remarks in his notes that it was a male, having the " head greenish 
yellow, clouded with black; opercula dull pinkish. Upjjer parts dirty grayish and yellow; under 
parts white, blotched with yellow; ventral and pectoral fins grass green; dorsal, ultramarine 
blue and green. Tail blotched (spotted?) with black." 
The teeth on the limbs of the lower jaw of this specimen extend backwards only half their 
length. Tongue apparently destitute of teeth. Branchial rays, 11. 11. Total length, 25.2 
inches. Length of head, 7 inches. Depth of hump, 7 inches. 
The Indians say that this salmon is usually quite fat, and that as food they like it very much. 
They state that it enters Puget Sound and the rivers on alternate years, it being very rare for 
even a single individual to be caught in the intermediate season. The "run" of the huddoh in its 
regular years is large, coming in vast numbers, comparing favorably, in this respect, with the 
satsup, slcoioitz, or Tl-hwhai. According to the natives of our coast, the liunch-back Heyer retui-ns 
to the sea after spawning, but die in fresh water. In this respect tliey again agree witli the 
Kamtschatka fish. — (See beyond.) 
Mr. George Gibbs says: Hunnoh come only every second year. The Indians say that when 
they do come there are always great abundance of salmon berries and other berries, and the 
summers are very warm. In the summer of 1853, when Captain McClellan's jjarty were in the 
Yakima country, berries were very abundant and salmon scarce, while tlie reverse was the 
case in 1854. The hmmoh arrive early in August, and last a month. Tlie I'eniale is like tlio 
others. The males have a large hump on the back, and an immense head ; llesli c>f tlie 
males white, females red. Upper jaw shuts over the under. The males have large hooked
