through the winter. When the warm days of spring return these 

 fish leave the deeper water and run up stream into the shallow, 

 swifter portions. This spring run of the suckers was, in the 

 early days, one of the phenomena in Indiana and Illinois which 

 never failed to attract the attention and excite the interest of those 

 who were at all observing. 



The Redhorse may be readily known from all other species of 

 suckers of this region by the following description, based on the 

 one Maxinkuckee specimen : 



Head 4.2 in length ; depth 3.9 ; eye 4.75 in head ; snout 2.6 ; in- 

 terorbital 2.5; dorsal I, 13; anal 7; scales 7-42-4. Body stoutish, 

 varying to moderately elongate, considerably compressed, dorsal 

 outline arched; head rather long, bluntish, rather broad, flattened 

 above; lips full, the nose projecting; lower lip strongly plicate. 

 Color in life yellowish or light rosy above, paler on sides, whitish 

 beneath ; fins more or less red, fading to light yellow in alcohol. 



16. ROT-GUT MINNOW 



CAMPOSTOMA ANOMALUM (Rafinesque) 



(Plate 9) 



This minnow is common in streams from central New York 

 westward to Wyoming and south to Tennessee and Texas. It is 

 usually most abundant in deep or still places in small streams with 

 muddy bottom. In the spring it runs into the smaller brooks at 

 spawning time. Although not a lake fish it occurs in Maxinkuckee 

 in some numbers. In July and August, 1899, more than 30 speci- 

 mens were seined in various places about the lake, though chiefly 

 in the small streams flowing into it. It was most abundant in 

 Aubeenaubee Creek ; it was found also in Norris Inlet, Culver Inlet 

 and the Outlet. Only rarely have we taken it in the lake proper; 

 two were got July 25, 1899, near the pumping house of the Van- 

 dalia railroad in the northwest corner of the lake on sandy bot- 

 tom covered with Hydrodyction and other aquatics, and another 

 was obtained near shore west of Lakeview Hotel, June 18, 1901. 

 The smallest specimen in our collection is 2 inches long, the largest 

 5.625 inches. 



This species is known also as Stone-roller, Stone-lugger, Steel- 

 backed Chub, Mammy and Doughbelly. It attains a length of 5 

 to 9 inches. As a food fish it possesses very little value, albeit, it 

 often adorns the small boy's string. Its flesh is soft and doughy, 

 full of small bones, and quick to decay, hastened, no doubt, by the 

 character and quantity of food usually found in the remarkably
