FISHES OF TEXAS AND THE RIO GRANDE BASIN. 115 
plainest markings being at about one-third the distance from the tips of the tin ; caudal 
like the soft dorsal, but the colors deeper; all the other fins unmarked. 
From Etheostoma lepidum, which this species most resembles and which we at first sup- 
posed it to be, it differs chiefly in the squamation of the cheeks. In that species the cheeks,' 
as well as the opercles, are scaleless, while in this the cheeks are densely scaled. It also 
differs from E. lepidu.in in having smaller mouth, shorter, blunter, more decurved snout, and 
in the slightly smaller scales. In lepidum the number of scales in a longitudinal series, in 
9 specimens from Comal Creek, varies from 48 to 54, while in this species the variation is 
from 54 to 61. This species resembles Etlieostoma ceeruleum also, but in that species the 
opercles are more or less scaled and the cheeks naked or very nearly so ; the scales are also 
larger in coeruleum and the color is different. The types of this species consist of two 
specimens, If and 2 inches long, respectively, obtained in Comal Creek at its beginning in 
the largest of the Comal Springs, at New Braunfels, Tex., December 3, 1891. (U. S. N. M. 
No. 44840-) . 
163. Etheostoma micropterus Gilbert. “ A single specimen If inches long; collected by Mr. E. 
Wilkinson, at Chihuahua, Mexico. U. S. N. M. No. 38245.’' (Type, Gilbert, 1890.) 
164. Etheostoma australe Jordan. Chihuahua River (as Diplesion fasciatus types, perhaps only in 
part, Girard, 18596, and as Etheostoma australe types, Jordan, 1888). Rio de las Conchas, 
Chihuahua (as Etlieostoma scovelli types, Woolman, 1892). The types of E. australe were 
found among the original types of D. fasciatus (No. 24625, M. C. Z.). 
165. Etheostoma jessise (Jordan & Brayton). Sabine River at Longview (Jordan & Gilbert, 1886). 
166. Etheostoma fusiforme (Grd.). Rio Seco and Rio Leona at Uvalde (as Boleosoma gracile types, 
Girard, 18596), and (as Pcecilichtliys gracilis, Synopsis). Trinity River at Dallas (Jordan & 
Gilbert, 1886). We have 3 specimens from Buffalo Bayou at Houston, 42 from Sims Bayou 
near Houston, 12 from Hunter Creek near Houston, and 1 from Neches River east of Pales- 
tine. The cheeks and opercles on all of these specimens are densely scaled, and the lateral 
line is developed on 20 to 22 scales. 
167. Etheostoma lateralis (Grd.). Mouth of the Rio Grande del Norte (as Alvarius lateralis types of 
genus and species, Girard, 18596). Rio Grande (as Pcecilichtliys lateralis, Synopsis). 
168. Etheostoma fonticola J. & G. Rio San Marcos (as Alvarius fonticola types, Jordan & Gilbert, 
1886). This interesting little darter was found in abundance in Comal River at New Braun- 
fels and the collection contains 43 specimens taken there. One specimen was found in 
Dickinson Bayou very close to brackish water. This is one of the smallest of darters, the 
largest specimens scarcely exceeding l.£ inches in total length. 
XXXIII.— SERRANIDiE. THE SEA BASS. 
169. Centropomus undecimalis (Bloch). Eobalo. Galveston (Jordan &> Gilbert, 1882). A few 
fish of this species were examined in the market at Corpus Christi, but we saw none at Gal- 
veston. 
170. Roccus chrysops (Raf.). White Bass. Red River at Fulton, Ark. (Jordan & Gilbert, 1886). 
171. Morone interrupta Gill. Yellow Bass. Common in the lower portions of the San Jacinto and 
Trinity rivers, from which it is brought in considerable numbers to the Houston market. 
XXXIV.— SFARIDiE. THE SPAROID FISHES. 
172. Lutjanus caxis (Bloch & Schneider). Gray Snapper. Brazos Santiago and mouth of Rio 
Grande (as Neonw.nsis emarginatus, Girard, 1859, pi. ix, figs. 5-8). 
173. Lutjanus aya (Bloch). Red Snapper. This important food-fish is brought to the Galveston 
market from banks not far distant. 
174. Rhomboplites aurorubens (C. & V.). Brazos Santiago (as Conodon antillanus, Girard, 1859). 
175. Orthopristis chrysopterus (L.). Pigfish; Sailor’s Choice. Indianola and Brazos Santiago (as 
Ortliopristis duplex types, Girard, 1859, pi. ix, figs. 1-4). Galveston (as Pomadasys fulvomac- 
ulatns, Jordan & Gilbert, 1882). Three specimens of this were gotten at Corpus Christi, 
where it is of some value as a food-fish. An example 9 inches long gives the following meas- 
urements: Head, 3£; depth, 2); eye, 5); D. xn-15; A. in— 13 ; scales, about 55 in length of
