SUCKLE Y MONOGRAPH OF THE GENUS SALMO. 143 



]!^attian Olney, esq., long a resident at the Dalles, Oi'ogon, writes that 

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

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

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

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

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

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



Male. — 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 

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

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

 and irregularshapes, and occupying from three to five scales. The largest 

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

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

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

 crescentic. Scales very large and adherent. A row of teeth on the 

 tongue, and another on the vomer. 



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

 male. Caudal more furcate. ]!*?o fleshy projection from the chin. 



Youug, {S. 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 female is uniform silvery-gray, 

 darker on the back and head. Subquackangular 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 Maine." Uuiou 

 River, Maine, Saint Croix River, Passamaquoddy Bay. 



Diagnosis. — From the young of 8. namaijcusli and 8. sisl-owet, by the 

 presence of its black spots ; also bj' the creseentic-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 ; that of the 

 female is more so than that of the male. The young 8. sehago may
