NOTES ON ALASKAN FISHES. 



Gastbrosteus PUNGiTius Linn., subsp. brachypoda. Stickleback (Esk. Lluk- 

 clmgulc). 



32931. Audi'aevsky. Twenty-three specimens. 



32935. (119.) Yukon River, winter 1877-78. Two specimens. 



32986. (78 a.) Saint Miohaels, summer 1877. 



Several hundred Sticklebacks from salt pools near Saint Mioliaels. 



This is an extremely abandaut species from Bering Straits south to the Kuskoquiiu Eiver in 

 all the brackish pools, tide creeks, and adjacent pools and sluggish streams of fresh water. In the 

 marshy country between the mouths of the Yukon and the Kuskoquim they are particularly numer- 

 ous, and are caught in great numbers in dip nets, forming an important item in the food-supply of 

 that district. They are larger there than elsewhere, attaining an average of about 2 inches in 

 length. 



Charles Peterson, a fur trader, told me that the last of October one season he was on a stream 

 connecting the lakes of the Cape Vancouver district with the Lower Kuskoquim and saw a con- 

 tinuous line of these fish about 5 -inches wide passing up from the Kuskoquim to these lakes upon 

 each side of the stream. 



Aboat Saint Michaels the Sticklebacks always leave the small streams and gather along the 

 sea-shore in schools as cold weather approaches.

32851. (1.) Unalaska. 

 Bough Flounder (tTnalaska; Aleut, Oa-hok). — A curious species, with large rough scales 

 scattered over the upper surface, with bare skin between ; color light olive, a little darker on oper- 

 cujum. The fins are light reddish orange, with black bars extending from the body to the tip of 

 the fins. Also on the tail the same. The bases of these spots slightly color the white of the under 

 surface. This species grows to 20 or more inches in length and weighs several pounds. Under 

 pectoral and ventral fleshy red. 



32914 (83). Saint Michaels, August, 1877. 



Bough-bached Flounder. — This species has very nearly the same habits as its smooth-backed 

 relative about the shore of Korton Sound, where it is the more common of the two species, and 

 attains by far the larger size.
