27. Lepomis pallidus (Mitchill). Blue perch, (b.) Common at Weldon. Probably occurs at Ply- 
mouth, but was not detected there. 
28. Lepomis gibbosus (Linnaeus). Robin; Yellow-belly; Becl-belly. (a, b.) Very common. Regu- 
larly exposed for sale in Plymouth, where it is caught in gill nets with Centrarchus macrop- 
terus and Chcenobryttus gulosus. 
29. Micropterus salmoides (Lacdpede). Chub. ( a , b.) Common. 
30. Etheostoma nigrum olmstedi (Storer). (a.) Fourteen specimens. 
31. Perea flavescens (Mitchill). Raccoon perch, (a.) Abundant. 
32. Stizostedion vitreum (Mitchill). Brook trout; Salmon. (a,b.) At a seine fishery near Plymouth 
an example 2 feet long was seen. While not common in the river, several fish, mostly under 
a foot in length, are taken at nearly every haul of the large shad seines. At Weldon the 
fish is rare and was not observed, although it was reported by the fishermen under' the name 
“ salmon.” 
33. Roccus lineatus (Bloch). Rock. ( a,b .) Very abundant during the shad season. Caught chiefly 
in seines, the most important fishery being about 2 miles above Plymouth. The fish ascend 
the river as far as the falls near Weldon, where they spawn, according to Mr. Worth. 
34. Morone americana (Gmelin). Perch; Silver perch. ( a,b .) Abundant, but less numerous than 
formerly in the lower river. 
35. Paralichthys lethostigma Jordan & Gilbert. Flounder, (a.) The tendency of this species to 
ascend fresh-water streams has often been observed, but its occurrence so far up the muddy 
waters of the Roanoke River is a matter of unusual interest. The fish is said to be quite 
rare in the vicinity of Plymouth, 2 miles above which place, on April 8, a specimen, about 
2 feet long, was taken in a seine, and on April 11 another example, 8 inches long, was 
obtained.
