SUCKLEY MONOGEAPH OF THE GENUS SALMO. 143 



Nathan Olney, esq., long a resident at tlie Dalles, Oregon, writes that 

 this species does not go down to the sea, but that the Indians take it all 

 the year round, except during the coklest weather in winter, and then, 

 perhaps, because they do not fish for it. He adds that he has eaten 

 them as late as December and as early as February, and thinks tbat if 

 they do go to the sea, they "run" all the year.

Sp.Ch.—^[ Based on three specimens in the Smithsonian collection.] 



ilfftfe. — Head contained nearly four and a half times in the total length 

 of the fish. Pectorals quite long, reaching to a line perpendicular 

 to a point about half an inch anterior to first ray of the dorsal. Gape 

 line of mouth much arched. Point of lower jaw armed with a conical 

 tlesh knob, projecting upward. Sides of the body, principally above 

 the lateral line, covered profusely with large black spots, of roundish 

 and irregular shapes, and occupying from three to five scales. The largest 

 black spots on the fish are those on the oi^erculum and pre-operculum. 

 Lower fins and tail unspotted, and of a bright color, bordered with 

 dark, (as seen in alcoliolic specimens.) Free margin of tail handsomely 

 (Tesceutic. Scales very large and adherent. A row^ of teeth on the 

 tongue, and another on the vomer. 



Female. — (SiJeeimen about 17 inches long.) Spotted much as on the 

 male. Caudal more furcate. No flesh}^ projection from the chin. 



Young, {8. gloveri, Grd). — According to Dr. Girard, have a few small, 

 reddish orange dots in the middle of the black spots. These seem to be 

 wanting in the adult. The color in the fem^ile is uniform silvery-gray, 

 darker on the back and head. Subquadrangular or subcircular black 

 spots are observed upon the sides of the head, behind the eyes, along 

 the back and half of the flanks, also on the dorsal and caudal fins, to 

 near the edge. In the male the same colors exist, but spread all over 

 with a reddish tint, more intense on the flanks and beneath than on the 

 head, back, and dorsal, and caudal fins where the red is sometimes but 

 faintly indicated. 



Hab. — Lakes in the "southern part of the State of Maiin\." Union 

 River, Maine, Saint Croix River, Passamaquoddy Bay. 



Diagnosis. — From the young of >S^. namaycush and 8. sislxOivet, by the 

 presence of its black "spots ; also by the cresy3)itic-shaped extremity of 

 the tail — that of both of the other species being strongly furcate. This 

 species, however, when not full grown, has a forked tail; th.it of the 

 female is more so than that of the male. The 3'oung S. scbcujo may
