The body is rather elongated, with the abdominal profile more curved than that of the back.' But the proportions of one part to the remainder in this fish vary considerably, not merely consequent on the locality it inhabits, but likewise with its age and the season: thus in the young there is a comparatively largo head and eyes, a short snout and rounded body : but as the adult stage is attained there is greater depth of the body due to a more prominent abdomen.* After breeding, the kelts are recognizable by low, lanky bodies and long heads. The length of the head varies with the age and sex of the specimen, being comparatively slightly longer in the par than in the female grilse or salmon, in which latter, as age advances, the head becomes comparatively shorter, whereas in the male it is longer than in the female. The length of the head is from 4j to 4| or even 5 in the par and male salmon to 5 or 5;^ in the female salmon and grilse, the caudal fin is from 6 in the par to 7h in the salmon of the entire leno-th: while the height of the body (which is greatest beneath the origin of the dor'sal fin) is from 4^ to 5 in the total length. Eye—situated slightly in front of the middle of the length of the head in the par (fig. 13), or nearly in the middle of that length in breeding males (fig. 14) and comparatively much smaller in adult than in young fish: interorbital space convex and equal to about 2/3 the length of the postorbital portion of the head in young, but more in old fish. Snout much produced in the male, and during the breeding season the extremity of the lower jaw is provided with a strongly curved prominence which in old specimens precludes the closure of the jaws. The posterior extremity of the maxilla reaches to beneath the middle of the eye in the par, but beyond i
