LAMPREYS AND FISHES OF INDIANA. 239 



Umbea limi (Kirtland). 

 Mud Minnow. 



Jordan and Gilbert, 1882, 8, 350; Blatchley, W. S., 1885, 1, 12 

 (synonomy). 



Form compressed, the caudal peduncle deep. Depth in the length, 

 four and one-fourth. Head short, about four times in length. Mouth 

 moderate, little oblique, the maxillary reaching the pupil. Whole head 

 scaly. No lateral line. Scales, thirty-five along the side, about fifteen 

 in a transverse row. Dorsal rays, fourteen ; anal rays, eight. Color 

 very dark, the sides usually with pale, irregular cross-bars. A vertical 

 black bar at the base of the caudal. Length about four inches. 



Canada to Minnesota and south to Indiana and North Carolina. In 

 Indiana has been taken at many points. Carroll County (23, '88, 48); 

 White River, at Indianapolis (i, '77, 376); lakes of Laporte County, 

 St. Joseph's River, Mauraee River, Tippecanoe River (1, '77, 44); region 

 of Monroe County (:?J, '84, 204); Whitley County, Marshall County 

 {4, '88, 159); Terre Haute (4, '88, 167); Vigo County {16, 95); Wina- 

 mac and Winchester; Eel River Basin (4, '94, 38). 



This species appears to delight in swampy situations. It often buries 

 itself in the mud at tbe bottoms of clear ponds and quiet streams, and on 

 stirring up such places one may sometimes find numerous fishes, where 

 before none were to be seen. Professor Forbes {H, '78, 78) determined 

 the food of this fish to consist of water-mites, the larvse of various insects, 

 entomostraca and small mollusks. Elsewhere {l^.. No. 6, 73) he 

 informs us that it also eats a considerable per cent, of low vegetable 

 matter. 



Family LUCIID.E. 



PIKES AND PICKERELS. 



Body elongated, slightly compressed, and often of large size. Heads 

 long, with produced and depressed snouts. Mouth large and armed with 

 strongly developed teeth. Margin of upper jaw formed mostly by the 

 maxillaries. A supplemental bone present behind the maxillary. Teeth 

 on the premaxillaries, vomer and palatines. Scales cycloid, small. 

 Dorsal fin placed far back, opposite the anal. No adipose fin. 



Contains only the single genus Lucius (Jordan, 4, '88, 111). This is 

 represented in Indiana by three species.
