this species, 8 inches long. The locality given on the label is Brownsville, Tex. The name

IX.— CYPRINIDiE. THE MINNOWS. 
32. Campostoma ornatum Grd. Chihuahua River and a tributary only a few miles long (type, 
Girard, 1856, and Girard, 1859, pi. xxv, figs. 1-4). Chihuahua River (Synopsis). The type 
(U. S. N. M. No. 77) is about 5 inches long and is in fair condition. The dorsal fin is still quite 
black, having held its color remarkably well. There are about 82 scales in the lateral line. 
33. Campostoma anomalum (Raf.). Cadereita and near Monterey, New Leon (as Campostoma 
nasutum types, Girard, 1856). Cadereita and Acapulco, New Leon (as Campostoma nasutum,

River (Synopsis). There are 16 specimens, 2| to 4 inches long (U. S. N. M. No. 76), recorded 
as the types of this species. The scales in the lateral line vary from 45 to 48, and thus appear 
to be a trifle larger than in C. anomalum, from which it does not seem to differ otherwise.
