26. Micropterus salmoides (Lac^pfede). S. 
The Large-mouthed Black Bass is found only in the lowland streams. It is com- 
mon in Swift Creek. 
27. Micropterus dolomieu (Lacdpide). L. 
The Small-mouthed Black Bass abounds in all suitable places in the upland tribu- 
taries of the James. Several localities, as Eagle Eock, Gala Water, Craig’s Creek, 
etc., are noted among anglers for the abundance of bass. The species seems to be 
indigenous in this river, though not in the Potomac. It rarely ascends the small 
creeks like Buffalo or Elk. 
28. Lepomis auritus (L.). L.,B.,N.,S. “ Yellow Belly.” 
This species is generally common in the tributaries of the James. It ascends 
streams further than the next species. 
29. Lepomis gibbosus (L.). L., S., N. 
Generally common, especially in the Lower James. 
30. Roccus lineatus (Bloch). S. “Rock.” 
Young specimens taken in Swift Creek. 
31. Etheostoma flabellare (Eaflnesque). B. 
Generally common, especially in swift shallow brooks. 
32. Etheostoma nigrum (Rafinesque) var. umiZare Jordan. B., L., N., S. 
Extremely common, except in the trout-brooks ; very variable. 
Many specimens from Buffalo Creek and the specimens from Loch Laird and Elk 
Creek apparently belong to the form called Boleosoma vexillare. None of these 
exceed 2 inches in length. The female of this form has the ordinary speckled colora- 
tion; the male is gray with the edges of the scales above more or less dusky, and the 
head is nearly black; spots on back and sides faintly marked. First dorsal very 
high, chiefly black, especially anteriorly; second dorsal and caudal spotted; ventrals 
and anal dusky or black. 
Cheeks and nape naked, opercles scaly, t). VIII-12, IX-11, IX-11, IX-12, 
IX-12, in five specimens. Scales 38, 39, 40, 40, 41, 42, 38, 38, 39, in nine specimens. 
Lateral line usually not quite complete. 
The original type of vexillare (from Eappahannock Eiver at Warrenton) had D. 
VIII-10, scales 35, but was otherwise similar to these. Vexillare doubtless repre- 
sents a slight variety of B. nigrum^ which may be called E. nigrum vexillare. 
The three specimens from Swift Creek are a little more slender, with smaller scales 
and the usual pale, speckled coloration. Scales 43, 45, 47, in three specimens. One 
of these has the cheek well scaled as in var. olmstedi. The others have the cheek 
naked as in vars. nigrum, effulgens, and vexillare. 
33. Etheostoma longimane Jordan. B., N., E. 
This graceful little darter is very abundant in the tributaries of the Upper James, 
especially in weedy places where the current is swift. In Buffalo and Elk Creeks it 
was found to be the commonest of the darters. 
34. Etheostoma aspro (Cope & Jordan). L. 
A single specimen, similar to those found in the Roanoke, was taken in the James 
River at Lick Run. Scales 64 ; cheeks scaly.
