Salmo Salar Linnaeus. "Salmon." 



Introduced in the Delaware River, and Harmsworth mentions 

 subsequently that they had been taken one season in most shad 

 fisheries from Fort Delaware to the Water Gap. 8 I have no recent 

 information and never saw an example. 



Salvelinus fontinalis (Mitchill). "Brook Trout." 



Several streams in Kent County were reported, some years ago, 

 as having been stocked with brook trout. 9 Though apparently rare 

 or entirely absent in suitable localities at present, it is likely to have 

 been indigenous perhaps in some streams in the northern portions of 

 Newcastle County in early times. No examples. 



Osmerus mordax (Mitchill). "Smelt." 



Recorded many years ago from the Brandywine Creek at Wil- 

 mington. 10 No examples. 



Anguilla chrisypa Rafinesque. "Eel." 



Abundant in almost all waters. Many have been taken about Lewes, 

 and in Indian River Bay quite an eel-pot industry is carried on, though 

 the eels taken in these pots are all rather small or of moderate size. 

 My examples from Mispillion Creek, Milford, Brown's Branch near 

 Harrington, Armstrong's Creek, Newcastle and Wilmington. 



Leptocephalus conger (Linnaeus). 



No examples. Reported about the breakwater at Lewes, where Mr. 

 F. J. Keeley secured one of 15^ pounds. 



Hybognathus nuchalis regius (Girard). 



A few from the Brandywine Creek near Wilmington. 



Pimephales notatus (Rafinesque). 



No examples. Said 11 to range from the "St. Lawrence River to 

 Delaware." 



Semotilus bullaris (Rafinesque). "Fall Fish." 



Abundant in the Christiana Creek basin. Dr. Phillips has found 

 it in Burrow's Run, the Red Clay Creek throughout its course, Mill 

 Creek near Hockessin, and the White Clay Creek near its mouth. My 

 examples from near Holly Oak in a small run, and the Brandywine 

 basin near Wilmington. 



Semotilus atromaoulatus (Mitchill). 

 Abundant in the Christiana upland basin. Dr. Phillips has found
