Bichardsonius egregius (Girard). Red-striped shiner. 



This beautiful little fish is almost universally distributed throughout the brooks, rivers, and lakes 

 of tlie region.^ It is found not only in the lower courses of the rivers where the water is deep and 

 quiet, but it also stems tlie swift currents of the high mountain tributaries, following closely in the 



o R. egregms has been reported from two localities in the Sacramento Valley (Bulletin, United States Bureau Fisheries, vol- 

 XXVn. p. 135). On direct comparison with examples from the Truckee Basin, the specimens upon which this report was based, 

 including the type of Ph»xinus clevelandi, were found to differ in no respect from typical individuals of R. egrcgms. The writer 

 has at different times attempted to secure specimens of this spedes from the Putah Basin, including Aetna Springs Creek, the 

 supposed type locality of P, clevelandi, but without success, and it seemed safe to conclude that it is not a native of that basin. 

 Now, Rutter's discovery of the species in a tributary of Feather River reopens the question. In this connection, however, it 

 will be recalled that Agosia robttsta. Pantosteus lahontan, and Catostcrnius iahocnsis were also reported by the same author from 

 a tributary of the Feather River. Since neither of these four forms has been seen elsewhere in the Sacramento River, excepting 

 possibly R. egregius as P. clevelandi. the suggestion is offered that either these species have been recently introduced along with 

 trout from the Truckee Basin or that Rutter was lead into an erroneous statement from a confusion of labels.
