band; pectorals yellow, banded with olive; anal faintly spotted with 

 black. In life the adult example was olive green, straw color below ; 

 back with 5 obscure, dusky, cross blotches ; 9 obscure, dark, olive cross 

 blotches on sides; a small, dark, caudal spot; snout and nape dashed 

 with orange; cheeks yellow; first dorsal pale olive, with darker olive 

 spots at base; a broad band of brilliant orange toward margin, the 

 edge dusky; soft dorsal and caudal light yellow, with bands of black 

 spots ; anal pale yellow, with 2 rows of olive spots ; pectorals and ven- 

 trals yellow, with olive spots ; ventrals edged with orange. The smaller 

 specimen had the dark blotches on side inky black, the back more 

 sharply mottled, and the orange on dorsal very faint. Length of type 

 5i inches. Two specimens of this species were taken in swift water in 

 the Roanoke River, near the city of Roanoke, Virginia. A splendid fish, 

 probably the largest of all the darters, looking like a Ludoperca. (rex, 

 king.)

1417. PERCINA CAPRODES (Rafinesque). 

 (Loo PERCH*; ROCKFISH ; HOG MOLLY; HOGFISH.) 



Head 4 to 4|; depth 5 to 6i; eye H in snout, 4 in head. D. XIII to 

 XVII-12 to 17; A. II, 9 to 12; scales 9-90 to 95-15, pores 76 to 93. Body 

 elongate, compressed. Head long and pointed, depressed and sloping 

 above. Mouth small, quite inferior, the maxillary not reaching to the 

 front of the eye. Cheeks, opercles, and nape scaly (the nape naked in var. 

 zebra)', cheet naked. Fins rather low. Middle line of belly with a row 

 of enlarged caducous scales ; pectoral about as long as head ; anal spines 

 feeble, subequal, or the second the longer; caudal truncate; vertebrae 

 23+21=44. Color yellowish green, or yellow, with about 15 transverse 

 dark bands from the back to the belly, these usually alternating with 

 shorter and fainter ones, which reach about to the lateral line ; a black 

 spot at the base of the caudal ; fins barred. Length 6 to 8 inches. Great 



*The Log Perch is the giant of the family, the most of a fish, and therefore the least of a 

 darter. It may be readily known by its zebra-like colors. Its hue is pal* olive, silvery below, 

 darker above. On this ground color are about 15 black vertical bars or incomplete rings, alter- 

 nating with as many shorter bars which reach only halfway down the side. The hindmost 

 bar forms a mere spot on the base of the tail, and there are many dots and speckles on the fins. 

 The body is long and slender, spindle-shaped, and firm and wiry to the touch. The head is flat 

 on top and tapers into a flat-pointed snout which is squared oft' at the end like the snout of a 

 pig, and this resemblance is heightened by the form of the small mouth underneath it. From 

 this pig-like snout has come the scientific name caprodes. This is a translation of the older 

 name of "hogfish," which Rafinesque heard applied to it in his time and which is still used in 

 the same regions. Percina reaches a length of 6 or 8 inches and it may readily be caught on a 

 small hook baited with a worm. We often meet au urchin with two or three of them strung 

 through the gills on a forked stick along with "red-eyes," "stone toters," "hornyheads," 

 and other "boys 1 fish.". We find Percina usually in rapid and rather deep water. We rarely 

 hnd them small enough for ordinary aquarium purposes; and the living specimen before us, 

 though wonderfully quick and graceful in its movements, has shown little that is noteworthy, 

 save his courage, his fondness for angleworms, and a possible disposition to bury himself in the 

 sand. There is something in the expression of his face, as he rests on his "hands and feet" 

 on a stone, that is remarkably lizard-like. suggesting the Blue-tailed Skink (Ihmeoes fasciatus).
