FISHES OF LORAIN COUNTY, OHIO. 23 
Very rare. Ihave but two records, and it is almost unknown 
to the fishermen here, though common in the eastern part of the 
lake. 
FAMILY XII. PERCOPSID A. THE TROUT-PERCHES. 
53. Perecopsis guttatus Agassiz. TROUT-PERCH. 
[Jord. Man. 195. O. St. Surv. 103.] 
Head conical, naked, scales rough, an adipose fin present, 
silvery, upper parts marked with dark spots made up of minute 
dots; length of largest taken 4 inches, but Jordan gives to inches 
as the length. 
Common in Lake Erie, Black River, and Beaver Creek this 
year (1891-2). I did not detect it before, and do not think it was 
““common.” Specimens taken in the latter part of April show well- 
developed spawn. 
FAMILY XIII. CYPRINODONTIDA. THE KILLI- 
FISHES. 
54. Fundulus diaphanus (Le Sueur). Barrep KILii- 
FISH: 
[Jord. Man. 203. O. St. Surv. 104.] 
Rather slender, depressed in front, compressed behind, rather 
light colored, with 8 to 16 (25 in eastern forms) narrow, dark cross- 
bands on szdes, dorsal fin soft and set far back: Length 3 inches. 
Taken once near Lorain. I found this little fish common near 
Huron and Put-in-Bay in the soft-bottomed, grassy inlets. One 
was seined out of open water in Put-in-Bay. All specimens taken 
here show broader, darker markings than eastern forms, several 
having only 8 bars on the sides. 
FAMILY XIV. UMBRIDA. THE: MUD-MINNOWS. 
55- Umbra limi (Kirtland). Mup-minnow. 
[Jord. Man. 212. O. St. Surv. 107.] 
A handsome, thick-set fish, dark greenish olive with mottled 
sides, a distinct black bar at base of tail, fins all soft, dorsal set far 
back. Length 5 inches. 
Very common in the soft black mud in sloughs and bayous, 
also very hard to get hold of insaid mud. Early in the spring they 
may sometimes be found in large numbers in the channels that run 
through the snipe marshes, and are even found in the open streams.
