FISHES-SALMONIDAE—SALMO SPECTABILIS, 
307 
The ground color of the dorsal region is greyish olive, scattered all over with dark and 
irregular, sometimes confluent, spots, which do not. extend quite to the lateral line. The dorsal, 
adipose, and caudal fins are spotted also. The rest of the body is uriicolor, yellowish grey or 
straw color ; the anal and ventrals being of the same hue, whilst the pectorals are blackish 
grey. The upper surface of the head is bluish black ; the sides blue and silver, with a golden 
reflect. 
The specimen here figured and described was caught, June 1st, 1855, in the Columbia river, 
and prepared by Dr. Geo. Suckley, under Gov. I. I. Stevens. “ They reach,” says the 
Dr., “ a weight of 40 to 50 pounds ; those of 30 pounds being quite common.”

3. SALMO SPECTABILIS, Grd. 
Spec. Char. —Body sub-fusiform in profile, very much compressed, the head forming about the fourth of the total length. 
Maxillar bone curved, extending to a vertical line passing somewhat posteriorly to the entire orbit. Anterior margin of dorsal 
fin a little nearer the extremity of the snout than the base of the caudal. Bluish grey above ; silvery beneath. Dorsal region 
and upper portion of the flanks spread over with light spots.

The only specimen which we have before us being in a rather precarious state of keeping, 
our description of the species must, of course, remain incomplete. All the fins being broken 
off from their very base, the length and shape of the caudal could not be ascertained. The 
abdomen itself is ruptured, and all the viscera are lost. In its general appearance it resembles 
Salmo lioodii most; is, however, distinguished from it by a more elongated and conical head, 
lienee a mouth more deeply cleft and the maxillary extending further back. 
The body is gracefully elongated, very much depressed, and fusiform in its outline, seen in 
profile. The head, which is elongated and sub-conical, enters three times and a half in the 
length, the caudal fin excluded, whilst in S. lioodii it enters six times and a half in the total 
length. The mouth is deeply cleft, and both jaws are even anteriorly. The teeth are 
conspicuous and acerated ; the largest may be observed upon the dentary (lower jaw) ; the next 
in size are those of the premaxillar (intermaxillar), on which bones there are but few ; the 
maxillar teeth are very much alike to those on the pterygoidian bones, but are somewhat less 
acerated and a little stouter; thev occupy most of the limb of the maxillary, leaving a tree space 
posteriorly equal to that situated behind the premaxillary, likewise toothless. The pterygoidian
