222 REPORT OF STATE GEOLOGIST. 



Abundant from New England to Dakota and Texas In Indiana it 

 probably occurs in every stream and pond. It has been reported from 

 the following localities : Carroll County {23, '88, 48) ; Franklin County 

 (5, No. 2, 6); Marion County (i, '77, 45, 377); lakes of Laporte 

 County, Maumee River, Kankakee River, Tippecanoe River, Lower 

 Wabash River, White River at Indianapolis (i, '77, 45) ; Lawrence 

 County (^5, '84, 204); Greene County (^-5, '84, 208); Posey County 

 (^, '88, 163) ; Vigo County {16, 95) ;"A¥abash River at Wabash; Eel 

 River basin (4, '94, 37) ; Laporte County {2J^, '93, 93). 



This species appears to prefer slow streams and grassy ponds. It is 

 sometimes found in numbers in the muddiest and apparently most unin- 

 viting holes In its food habits it appears to be omnivorous. Forbes 

 {llf.. No. 2, 81) found that its diet varies considerably in different situ- 

 ations. In some cases they had eaten altogether univalve mollusks. 

 Some were found to have filled their intestines with mud. Other speci- 

 mens had eaten only entomostaca, while one was discovered to have 

 filled itself with wild rice.

II, 1884. 



A species originally from Asia, introduced into Europe and America 

 as a food fish adapted for domestic culture, but which has escaped into 

 our streams. The body is heavy and reaches a length of one or two 

 feet. Dorsal rays, twenty, preceded by a stout spine, which is serrated 

 behind. Anal rays, about five, also preceded by a serrated spine. The 

 lateral line is complete. Scales, 6-40-5. In the "leather carp" the scales 

 are entirely absent, while in the " mirror carp" there are a few rows of 

 very large scales. Color, dusky above, brassy on sides and below. 



For further information regarding the carp the reader is referred to 

 the various publications of the United States Fish Commission. This 

 fish is now reared in many artificial ponds, and from these has escaped 

 and appears to be establishing itself in our streams. One specimen was 

 taken by the writer in a small branch of the Tippecanoe River at 

 Winamac, and another was seen on the border of Hyde Lake, near the
