Four collections of the blacknose shiner, Notropis heterolepis Eigenmann and Eigenmann, were made from three different streams in Clay, Dickinson and Osceola Counties, Iowa. Twenty-six specimens were collected. These are the only known specimens of this species collected from a stream environment in Iowa in the last twenty years. Thus, it was demonstrated that the species is not yet extinct in Iowa streams.
