FISHES OF TEXAS AND THE RIO GRANDE BASIN. 
113 
151 . Lepomis albulus (Girard). Rio Blanco fas Bryttus alb ulus types, Girard, 1857, and Girard, 1858, 
pi. vi, figs. 1-4). The type (U. S. N. M. No. 421) is 7 inches long and in excellent condition. 
Head, 2f; depth, 2|; eye, 4|; snout, 3£; scales, 7-42-12, 5 rows on cheek. 
152 . Micropterus salmoides (Lac.). Big-mouthed Black Bass; “ Trout.” Rio Frio and Rio Nueces (as 
G-rystes nuecensis types, Baird & Girard, 1854). Rio Blanco, Rio Frio, Rio Leon, Rio Seco, 
Rio Medina, Rio Brazos, Rio Nueces, Rio Leona, Rio Sabinal, Minneville River, Delaware 
Creek, Live Oak Creek, Dry Creek, Turkey Creek, Elm Creek, and San Pedro Creek; San 
Juan River, New Leon (as Dioplites nuecensis, Girard, 1858). Rio Frio, Rio Nueces, Live 
Oak Creek, Turkey Creek, Rio Leona, Elm Creek, Rio Sabinal, Dry Creek, San Pedro Creek, 
Minneville River, and San Juan River, New Leon (as Dioplites nuecensis, Girard, 1859, 
pi. i). Trinity, Llano, Guadalupe, and Medina rivers, and Johnson Fork of Llano River in 
Kimble County (as Micropterus floridanus, Cope, 1880). Red River at Fulton, Ark., Sabine 
River at Longview, Rio Lampasas at Belton, Rio Colorado at Austin, Rio San Marcos at 
San Marcos, and Rio Comal at New Braunfels (Jordan & Gilbert, 1886). Neches River east of 
Palestine, Trinity River and Long Lake at Magnolia Point, San Jacinto River at Lynch- 
burg, Dickinson Bayou near Dickinson, Buffalo Bayou, Hunter Creek, Big White Oak 
Bayou near Houston, San Marcos River at San Marcos, and San Antonio River at San 
Antonio. The big-mouthed black bass is, as the above list of localities shows, an abundant 
and widely distributed fish in Texan waters. It is not confined to the fresh-water streams, 
but is also found in brackish- water bayous. In Dickinson Bayou we found it associated 
with such salt or brackish water forms as oysters, shrimps, flounders, and Scicena ocellaia. 
With these were also found Lepomis pallidus, Ictiobus cyprinella, Notemigonus chrysoleucus, 
Lepisosteus platystomus, and Gerres gracilis. 
XXXII.— PERCIDiE. THE DARTERS. 
153 . Etheostoma pellucidum clarum (Jordan & Meek). Sand Darter. Red River at Fultou, Ark., 
and Sabine River at Longview (as Ammocrypta clara, Jordan & Gilbert, 1886). 
154 . Etheostoma vivax (Hay). Sabine River at Longview (as Ammocrypta vivax, Jordan &. Gilbert, 
1886). 
155 . Etheostoma phlox (Cope). Trinity River near Fort Worth (as Boleosoma phlox types, Cope, 
1880). Trinity River (as Ulocentra phlox, Synopsis). 
156 . Etheostoma chlorosoma (Hay). Three specimens of this little darter were taken in a pond 
on the bank of the Neches River east of Palestine, and one each in Kilper’s Pond and Buffalo 
Bayou at Houston. 
157 . Etheostoma shumardi (Grd.). Red River, Fulton, Ark. (as Gottogaster shumardi, Jordan & 
Gilbert, 1886). 
158 . Etheostoma caprodes (Raf. ). Log Perch. Rio Salado (as Pileoma carbonaria types, Baird & 
Girard, 1853). Rio Salado, Rio Medina, and San Pedro Creek (as Pileoma carbonaria, Girard, 
1859, pi. viii, figs. 10-13). Trinity River near Dallas and Llano River, Kimble County (as 
Percina caprodes carbonaria, Cope, 1880). Rio Colorado at Austin (as Percina caprodes, Jor- 
dan & Gilbert, 1886). Three specimens from Long Lake near Magnolia Point and one from 
the Neches River east of Palestine. The Long Lake specimens are quite thickly covered 
with larval trematodes occurring as small black specks scattered over the body with no 
apparent regularity, or, in other words, no one portion of the fish seems much more vul- 
nerable than another to the attacks of this parasite. This darter is a species which fre- 
quents clear running water or clear lakes and its occurrence in such stagnant bodies of 
water as that of Long Lake is unusual ; its being attacked by trematodes well illustrates 
one of the dangers which result from the transfer of any fish from clear, cool, running water 
to water which is more or less stagnant ami impure. Active species transferred to such a 
pond or bayou are almost certain to suffer from the attacks of trematodes and other para- 
sites, while those fishes which live habitually in such waters are less liable to be affected. 
159 . Etheostoma fasciatus (Grd.). Chihuahua River (as Diplesion fasciatus types, Girard, 18596). 
160 . Etheostoma scierum serrula (J. & G.). Sabine River at Longview (as Hadropterus scierus 
serrula var. nov. types, Jordan & Gilbert, 1886). Trinity River at Dallas, Rio Lampasas at 
Belton, Rio San Marcos afi San Marcos, and Rio Comal at New Braunfels (as Hadropterus 
scierus serrula, Jordan & Gilbert, 1886), The recent collection contains 42 specimens from 
F. C. B. 1892—8
