males of diaphaniis, while the individuals having the dark bars on a sil- 

 very ground are the females. 



This species is found along the Atlantic Coast in brackish waters, and 

 ranges in fresh- water streams and lakes westward to Colorado. In Indi- 

 ana, it has been taken in Lake Maxinkuckee and neighboring streams 

 (23, '88, 55; 4, '88, 159); Lakes of Laporte County and St. Joseph's 

 River {1, '77, 44). "In Lake Michigan it abounds about the sandy 

 mouths of tributaries, keeping in schools in the shallow water near the 

 edge of Calumet River," (Jordan, 14-, No. 2). 



Forbes (1^, No. 2, 78) found this species to have eaten mollusks be- 

 longing to the genera Pisidiuvi and Planorbis, larvae of dipterous insects, 

 Allorchestes, and Cladocera. He also informs us (14, No. 6, 71) that 

 about one-fifth of the food is composed of vegetable matter. The fish 

 appears to prefer the colder and clearer waters of streams and springs.

This fish prefers still waters, where it may be seen swimming near the 

 surface. Unlike some members of the same family, this species lays its 

 eggs, instead^ if hatching them within the body. As to its food, Forbes 

 (14, No. 2, '78) found in the stomachs of specimens examined the bones 

 of a small fish, various small insects, and small crustaceans. Elsewhere
