NOTES ON FISHES OBSERVED AT THE HEAD OF CHESAPEAKE BAY 
IN THE SPRING OF 1882; AND UPON OTHER SPECIES OF THE SAME 
REGION. 
By TARLETON H. BEAN, M. D., 
Curator of the Department of Fishes in the United States National Museum. 
Early in June, 1882, the writer made a short visit to the station of the 
United States Fish Commission near Havre de Grace, Maryland, while 
the work of hatching eggs of the shad and other economic fishes was in 
progress. An immense seine was in use here by the Commission, and 
in it were captured most of the species which are the subjects of the 
present brief sketch. Information concerning species not seen by me, 
but perfectly well known to persons employed at the station, and taken 
in the seine previous to the time of my visit, or by some other means of 
capture, was furnished by one of the most experienced of the fishermen, 
and is here reproduced. The species marked by an asterisk were taker 
June 9 and 10 and examined after they reached the Museum, where they 
‘are now preserved. The common names given are in use at Havre de 
Grace. 
1. Achirus lineatus (L.) Cuy. Hogchoke. 
2. Liostomus xanthurus Lac. Spot. 
The “ spot” is said to occur only in very dry seasons. 
3. Lepomis auritus (L.) Raf. Sun-fish. 
Said to be present throughout the year. 
4. * Lepomis gibbosus (L.) McKay. Moccasin. 
Said to be present all the year. 
5. Micropterus dolomiei Lac. Black Bass. 
6. *Perca americana Schranck. Yellow Perch; Ring Perch; Yellow Ned. 
In February yellow perch come into the creeks to spawn ; the spawn- 
ing season ends in March, when the fish go out to the flats. They re- 
mInain in the vicinity all the year. The maximum weight here is about 
2 pounds. 
7. Stizostedium vitreum (Mitch.) Jor. & Copel’d. Salmon Trout ; Salmon. 
This species is highly esteemed in the Susquehanna. In the year 
1862 or 1863 an individual weighing 8 pounds was sold at Bainbridge, 
Pennsylvania, for $2. 
8. Roccus saxatilis (Bl. Schn.) Jor. & Gilb. Rock. 
Rock-fish are said to be present from April to October, and to be 
most abundant in August and September on the flats in the celery 
ass. They are always plentiful, occurring in hundreds of thousands. 
hey will live in “ live cars,” and a great many are so kept now. The 
pecies reaches a length of 4 feet and sometimes weighs 60 pounds.
