26. Salmo gairdneri Ricliardsou. Sleelhead Trout; “Salmon Trout.'’ 
Seen in large numbers at Astoria and The Dalles. Not common in the Siuslaw, and only 2 speci- 
mens obtained in Upper Klamath Lake. While at The Dalles during the last week in September 
and the first half of October Mr. Alexander examined 4,179 steelheads, of these, 1,531 were males and 
2,648 females; 476 males, and 900 females were well developed, and would probably have spawned in 
four to six weeks. The remaining 2,803, he thinks, would not have spawned until some time in the 
spring. 
Sleelhead salmon taken by Mr. I. II. Taffe, at Celilo, September 18 to 22, 1896, and examined by Mr. Alexander.

Mr. Alexander states that not many steelhead are seen about Seattle until the latter part of Novem- 
ber or early in December, or about two months after they begin running up the rivers at the northern 
end of the sound. Daring the early part of January, 1897, a good many were taken near Seattle. 
They were considered equal in quality to those taken in other parts of the sound. Their eggs were in 
various stages of development; a few fish were spent, but themajority were well advanced and would 
have spawned in a short time.

Nineteen specimens from Sinslaw River at Florence, where it is abundant about the cannery wharf 
during the canning season. 
28. Gasterosteus cataphractus (Pallas). Alaska Stickleback.

obtained in Lake Washington by Mr. Alexander, where it was also obtained in 1892. 
30. Siphostoma griseolineatum (Ayres). Pipefish. 
One specimen, 10f inches in length, from the Siuslaw River near Point Terrace. It was caught in 
a 7-inch-mesh salmon gill net..
