Nelson (1887) records it from St. Michael and Norton Sound, where he says the run in the streams begins about September 1. The first examples ^oen by us were caught June 19, by trolling in the outer harbor at Nanaimo. After that date the lish was seen at most of the canneries visited, being in greatest abundance, however, at those canneries visited late in August. Dr. Gilbert, speaking of this species at Unalaska, say-: Two young were seined at Unalaska, June 16, 1890, the smaller of which, 100 mm. long, shows very conspicuous parr-marks. These have disappeared in the larger specimen, 225 mm. lone, which has also assumed more the proportions and appearance of the adult. In tin- specimen the spot- are more distinct than in the adult, being large, well defined, and close-set on head, back and dorsal tin, and the caudal fin is very indistinctly marked, the faint spots being confined to the outer rays of both lobes. It is a male with the testes so well developed as to make ii very probable that it would have sought the spawning-grounds within a few mouths. Three smaller specimens were taken in Herendeen Bay July 5. The smallest of these is 145 nun., the largest 185 mm. long. The distal half of the dorsal fin is black with the exception of the last two rays, which are entirely white. Mr. Rutter found the young common in sloughs along the edge of Karluk River near its source May 22. Forty-one specimens taken on that date were each about 1 25 in< lies long, 16 others were to 6 inches long. He gives the life color of a 6-inch specimen taken from th :ean June 18 as follows: Back olive brown thickly spotted with black: dorsal dusky
