BULLETIN OP THE UNITED STATES FISH COMMISSION. 
who has twice made a canvass of the fisheries of the entire Pacific Coast under very 
favorable circumstances. 
In 1895, Mr. William Barnum, of the United States Fish Commission, visited 
parts of Idaho, Utah, Oregon, and Washington, and obtained information regarding 
non-iudigenous fishes of those States that has been incorporated in this article. 
The writer desires to express special obligations to Mr. John P. Babcock, chief 
deputy of the California Fish Commission, for numerous courtesies which have con- 
tributed to the completeness and accuracy of this paper. Mr. Arthur G. Fletcher, 
of the same commission, has also furnished a number of interesting notes. 
Messrs. Babcock and Fletcher, cooperating with the writer, were able to secure 
accurate figures showing the monthly receipts of shad, striped bass, carp, and catfish 
in 1893 and 1894, which information is given elsewhere. 
To the following fish-dealers of San Francisco acknowledgment is due for their 
kindness in according free access to their books, from which an accurate statement 
of the extent of the trade in the species under discussion could alone be obtained: 
American Union Fish Company, J. H. Kessing, A. Paladini, Pioneer Fish Company. 
G. Camilloni, S. Tarantino, B. Caito, and P. Gusmani. 
The following-named gentlemen have courteously responded to inquiries and 
supplied useful data: Hon. George T. Myers, Portland, Oreg. ; Mr. James Crawford, 
fish commissioner, Vancouver, Wash.; Mr. F. C. Beed, ex-fisli commissioner, Astoria, 
Oreg.; Mr. Charles F. Lauer, The Dalles, Oreg.; Mr. George T. Mills, fish commis- 
sioner, Carson City, Nev.; Mr. W. H. ftidenbaugh, Boise, Idaho. 
THE CATFISH. 
INTRODUCTION TO PACIFIC STATES, AND RESULTS. 
At least three species of catfish— the white catfish (Ameiurus catus ), the yellow 
catfish or bullhead ( Ameiurus nebnlosus), and the spotted catfish ( Ictalurus punc- 
tatus) — inhabiting parts of the United States east of the Bocky Mountains have been 
transferred to the Pacific States. Catfish were taken to California in 1874 by Mr. 
Livingston Stone,* of the United States Fish Commission, and subsequently one or 
two species were introduced into Oregon and Washington. Mr. Stone’s assortment 
of eastern catfish consisted of 56 large Schuylkill catfish ( Ameiurus catus ) from the 
Baritan Biver, New Jersey, and 70 hornpouts or bullheads (A. nebulosus) from Lake 
Champlain, Vermont. The large white catfish were deposited in the San Joaquin 
Biver, near Stockton, Cal., and the bullheads were placed in ponds and sloughs near 
Sutterville, Sacramento County, Cal.; both plants were made on June 12, 1874. 
It appears from Mr. Stone’s account of his trip across the continent in 1874 that 
at Fremont, Nebr., on the Elkhorn Biver, he took on board some cattish from that 
stream, and that 18 of these were placed in the San Joaquin Biver, near Stockton, in 
conjunction with the other large catfish from New Jersey. Mr. Stone refers to these 
as “Mississippi catfish,” but this designation is not definite enough to conclusively fix 
their identity; and as no specimens have recently been observed, and as no examples 
are preserved in collections, the ichthyological status of this fish must be considered 
unsettled. Becent collections in the Elkhorn Biver and neighboring waters by the
