FISHES OF TEXAS AND THE RIO GRANDE BASIN. 
105 
This is a very variable species, a fact shown not only by the several nominal species 
which we have united in the above synonymy, but as well by the different individuals of any 
one of the types. However, as shown in the table, the variations are, chiefly a least, in parts 
which in this group are not of value for purposes of classification. The size and number 
of the scales have heretofore been used for this purpose, but, as may be seen, the variation 
in squamation among the individuals of any one of the types, for example, Tigoma pulchpa, 
is as great as among the types of the several nominal species. We have not been able to 
find the types of Gila gula, which probably also belongs here. 
84 . Leuciscus conspersus (Garman). Nazas River, Coahuila(as Gila conspersatjpe, Garman, 1881), 
Saltillo, Coahuila (as ? Cheonda modesta types, Garman, 1881). 
85 . Opsopceodus oscula Evermann. Neches River and Long Lake near Palestine. Buffalo Bayou, 
Sims Bayou, and Kilper’s Pond near Houston. Dickinson Bayou at Nicholstone (types, 
Evermann, 1892). 
86. Notemigonus chrysoleucus (Mitchill). Rio Seco, a tributary of the Rio Nueces (as Luxilus 
seoo types, Girard, 1856, and Girard, 1858). Dry Creek near Victoria (as Luxilus leptosomus 
types, Girard, 1856, and Girard, 1859, pi. xix, figs. 9-12). Brownsville (Jordan, 1878). 
Neches River, Long Lake, and Trinity River near Palestine. Sims Bayou, Kilper’s Ponds 
and Big White Oak Bayou near Houston. Dickinson Bayou near Dickinson (Evermann, 
1892). Fulton Creek near Creswell (Coate). The type of Luxilus leptosomus is inches long 
(U. S. N. M. No. 61) and is very mellow. It does not differ from Notemigonus chrgsoleucus. 
X. — CHARACINIDJE. THE CHARACINS. 
87 . Tetragonopterus argentatus (B. & G.). Upper tributaries of the Rio Nueces (as Astyanax 
argentatus types, Baird & Girard, 1854). Rio Nueces, Rio Leona, Rio Sabinal, mouth of the 
Rio Grande, Zoquico, Comanche Springs, Elm Creek, Turkey Creek, San Felipe, Devil River, 
and Brownsville (as Astyanax argentatus, Girard, 1859, pi. vm, figs. 5-9). 
XI. — HIODONTIDiE. THE MOON-EYES. 
88. Hiodon alosoides (Raf.). Red River at Fulton, Ark. (Jordan & Gilbert, 1886). 
XII.— ELOPIDiE. THE BIG-EYED HERRINGS. 
89 . Megalops atlanticus C. & V. Galveston (Jordan & Gilbert, 1882). 
XIII.— CLUPEIDiE. THE HERRINGS. 
90 . Clupea chrysochloris (Raf.). Red River at Fulton, Ark., and Galveston (Jordan & Gilbert, 
1882 and 1886). 
91 . Harengula arcuata (Jenyns). Nine specimens from Galveston and Corpus Christi. Clupea 
humeralis Cuv. & Val. and Harengula pensacolce Goode & Bean seem to be identical with this 
species. 
92 . Opisthonema thrissa (Osbeck). Galveston (Jordan & Gilbert, 1882). 
93 . Brevoortia tyrannus patronus Goode. Brazos Santiago (as Brevoortia patronus types, Goode, 
1878). Galveston (Jordan & Gilbert, 1882). One young specimen obtained by us at Gal- 
veston. The differences said to distinguish the Gulf menhaden from the common form are 
not of great value. Our specimen shows no differences in the scales, but the fins are a trifle 
larger or longer than in specimens of the same size from further north. 
94 . Dorosoma cepedianum (Le S.). Galveston (Jordan & Gilbert, 1882). Red River at Fulton, 
Ark., and Rio Comal at New Braunfels (Jordan & Gilbert, 1886). This worthless fish was 
very abundant in Long Lake near Magnolia Point and in Kilper’s Ponds at Houston. 
XIV.— ENGRAULIDiE. THE ANCHOVIES. 
95 . Stolephorus browni (Gmelin). Anchovy. The collection made at Galveston contains seven speci- 
mens of this species. 
96 . Stolephorus mitchilli (C. & V.). Galveston (Jordan <fc Gilbert, 1882). A few specimens taken 
at Galveston, Corpus Christi, and in Dickinson Bayou.
