The Nonindigenous Occurrences section of the NAS species profiles has a new structure. The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. Occurrences are summarized in Table 1, alphabetically by state, with years of earliest and most recent observations, and the tally and names of drainages where the species was observed. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. References to specimens that were not obtained through sighting reports and personal communications are found through the hyperlink in the Table 1 caption or through the individual specimens linked in the collections tables.

Means of Introduction: One of the collectors, G. A. Moore, thought that the Bricken Spring specimen represented a bait introduction, based on the fact that it was taken on the premises of Thomas Bricken, a bait dealer, who obtained his fish from the Arkansas and Red river drainages (Hubbs and Bonham 1951).

Status: Reported from a part of Oklahoma.

Impact of Introduction: The impacts of this species are currently unknown, as no studies have been done to determine how it has affected ecosystems in the invaded range. The absence of data does not equate to lack of effects. It does, however, mean that research is required to evaluate effects before conclusions can be made.

Remarks: Hubbs and Bonham (1951) noted that the Bricken Spring specimen to be typical of Notropis blennius blennius, one two subspecies recognized by some authors. Gilbert (1998) apparently did not recognize subspecies. In commenting on the belief that the Bricken Spring specimen represented a bait introduction, Suttkus and Clemmer (1968) remarked "perhaps this is true."
