Pimelodus affinis, described by Baird and Girard 1854, collected by John H. Clark in the “Rio Grande del Norte”. Now considered Ictalurus furcatus (Blue Catfish or Blue Channel Catfish), it was first described in 1840 by Valenciennes. Clark collected the specimen depicted here while part of the U.S. and Mexican Boundary Survey of 1851. He also collected the type specimen of Catostomus clarkii, the Desert Sucker (Plate 27, Vol. II, Part 2, Report on the United States and Mexican Boundary Survey), which is found in the Gila and the type for Catostomus plebeius, the Rio Grande Sucker. Baird’s official description of the latter indicates that Clark collected it in the Rio Mimbres.
