area. In A. rupestris the cheek scales are well developed, usually iu about nine rows. 
The scales on the breast are also more obscure in A. cavifrons, but tlie scales on the 
body are alike iu the two forms. There is no tangible difference in the profile, but the 
different squamation of the head seems to justify the recognition of A. cavifrons as a 
slight geographical variety. 
20. Lepomis auritus (L.). 
Common. The specimens belong to the noi-thern variety, with small scales on 
breast and cheeks. Lepomis ophthabiiicus (Cope), from some tributary of the Roanoke, 
is probably the same species. 
21. Lepomis gibbosus (L.). 
Scarce. 
22. Etheostoma podostenione Jordan & Jeukius. 
Very common, especially in swift waters among river weeds. Most abundant in 
Bottom Creek. 
23. Etheostoma nigrum (Rafinesque). 
One specimen of var. vexilJare (scales 40,41,) from Salem; many from Bottom 
Creek, above Alleghany Springs. 
24. Etheostoma roanoka Jordan & Evermaini. 
Very common in swift and grassy waters; one of the most elegant of the darters. 
25. Etheostoma aspro (Cope & Jordan). 
Several specimens, the longest 4J inches in length; most common in Bottom 
Creek in rather deep water. D. Xll-13, XIV-13 iu two specimens ; A. II-9, scales 
60, 64, 61 in three specimens. These specimens agree fairly with E. aspro from Illi- 
nois River. The dark blotches on the .^ides are smaller, less broadly confluent, but 
rather resembling widenings of a narrow black band. The scales are a little larger, 
those on the cheeks faint and imbedded, and iu one specimen wanting altogether. 
26. Etheostoma rex Jordan & Evermann. 
Two specimens of this superb darter were taken in the Roanoke River. The 
larger of these (5J inches long) was taken in the rapids under the bridge 2 miles 
southwest of Roanoke. 
27. Etheostoma flabellare (Rafinesque). 
Common ; scales 46. These specimens are not different from others from Indiana. 
F.— THE PAMLICO RIVER. 
The Pamlico River is abroad, tide- water estuary opening into the southern part 
of Pamlico Sound. Its principal tributary is known as Tar River, a stream which 
rises near tbe Virginia line, and flows southeast through pine forests into the head of 
the Pamlico. Collections were made in the Tar River, at a point 2 miles below the 
village of Rocky Mount. August 29 ; temperature 73°. 
In the Tar River, at the point referred to, a large dam crosses the stream. This 
dam rests on a ledge of granite, and for a long distance below the dam the bottom of 
the river is very rocky. There are a few deep holes iu the river, and some other 
points suitable for collecting. The rocks are covered with water-plants. The water 
iu the river was muddy, although it had not been raised by rains.
