Evarra Woolman 1894 Mexican forename that achieved some level of fame in an 1890 verse by Rudyard Kipling, “Evarra and His Gods,” which drew upon an Indian tradition of producing idols from oddly shaped stones, trees and other objects into “gods” that are recognizably in the image of the maker, who, in the verse, is named Evarra, a “maker of gods in lands beyond the sea” (Woolman did not explain his selection of the Evarra epithet; perhaps he simply gave a nice-sounding Mexican name to a uniquely Mexican fish)

Gila Baird & Girard 1853 allusion not explained, presumably referring to Gila River of Arizona and western New Mexico, USA, but Baird & Girard said the three taxa they included in the genus were all from the Zuni River of New Mexico; perhaps the authors believed the Zuni was part of the nearby but separate Gila basin, or selected Gila (reportedly derived from a Spanish contraction of Hah-quah-sa-eel, a Yuma Indian word meaning “running water which is salty”) as nothing more than a locally flavored name from the American Southwest

Gila pandora (Cope 1872) etymology not explained nor evident; Cope was unsure of the “truer affinities” of this species and mentions several genera to which it may belong, so perhaps its taxonomic ambiguity was a Pandora’s box, i.e., a source of troubles for Cope (M. H. S. Pérez, pers. comm.); another possibility: since Cope invested in silver mines in Colorado and New Mexico (ca. 1880), perhaps he named this fish for the Pandora mine and subsequent mining town (ca. 1875) just east of Telluride, Colorado, USA, 225 km away from type locality in Costilla County, Colorado

Lavinia exilicauda harengus Girard 1856 Medieval Latin for herring, probably derived from an Old English (haéring, heringas), Old Frisian (hêreng), Old High German (hâring), or similar Anglo-Saxon or Germanic vernacular, allusion not explained; since Girard’s specimens were missing scales, he may have been referring to a herring’s proclivity to shed scales when handled
