Several Uuuclred Sticklebacks from salt pools near Saint Michaels. 



This is an extremely abamlaut species from Bering Straits south to the Kuskoquim Elver iu 

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

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

 ous, and are caught in great numbers in dip nets, forming an important item iu 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 tish about 5 inches wide passing up from the Kuskoquim to these lakes upon 

 each side of the stream. 



About Saint Michaels the Sticklebacks always leave the small streams aud gather along (he 

 sea-shore iu schools as cold weather approaches.

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

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

 attains by far the larger size.
