blue cat, nor so highly esteemed; hut the two species are not 
kept separate in shipment to the market. 
11. Schilbeodes gyrinus. The only bullhead (as all small 
Siluridae are called in this general region) that we caught was 
a single specimen of this species, three centimeters in length. 
12. Ictiobus cyprinella. Buffalo. Very abundant. Caught 
and shipped in larger quantities than any other fish. When 
the price warrants, it is dressed by splitting up the back before 
shipping; otherwise it is shipped “in the round’ 7 together with 
carp, suckers, etc. 
13. Ictiobus urus. Deep-water Buffalo. During the 
summer of 1904, I attempted many times to select specimens 
which I could assign to this species, but without success. 
Fishermen point out what they consider a distinct “deep-water 
buffalo,” but in no case was I able to distinguish them by any 
constant characters from I. cyprineilla. At present I am very 
much inclined to doubt the distinctness of the two species. 
However, I hope to be able before long to return to this field 
and gather more detailed evidence on the subject. 
II. Ictiobus bubalus. Small-mouthed Buffalo. Occurs 
very much less abundantly than I. cyprinella. As market fish 
the two forms are not kept separate. 
15. Carpiodes velifer. Quillback. Hot very abundant, 
but one or two appeared in the big seine almost daily. As 
elsewhere, this form is very variable, and fishermen apply va¬ 
rious names. All specimens of Carpiodes examined by me, how¬ 
ever, could be referred to this species. 
16. Catostoynus commersonii. A number of young speci¬ 
mens were taken, near the mouth of the creek at the south end 
of Best Island. Ho large specimens were found, and the 
species probably belongs to the creek rather than to the lake. 
17. Moxostoma anisurum. Bed Horse. A single large 
specimen and a number of young were taken. 
18. Moxostoma aureolum. Bed Horse. Hot at all com¬ 
mon. In fact, to one who knows the abundance of Catostomids 
in the lakes and rivers of Minnesota tributary to the Missis¬ 
sippi, their comparative rarity in Lake Pepin, with the excep¬ 
tion of Ictiobus, comes somewhat as a surprise.
