The fish was originally described by Agassiz under the name Osmerus cordieri.

Description of the genus by Woodward 1901, p.247 “Head small and trunk moderately elongated, the maximum depth at the insertion of the dorsal fin. Mandibular suspensorium much inclined backwards, and cleft of mouth large; jaws slender, and maxilla not expanded behind; teeth minute, numerous and sharply pointed. Gill-rakers large and slender. Vertebrae about 45 in number, half caudal and half abdominal; the centra at least as long as deep, longitudinally striated; ribs delicate. No fin-rays elongated, but two or three in front of the median fins undivided and spinous. Pectoral fins with about 18 rays, relatively large and inserted just above the ventral border; pelvic fins smaller, with about 10 rays, opposed to the dorsal fin, which is nearly median and comprises about 18 rays; anal fin behind the dorsal, longer than deep, with 20 rays; caudal fin slightly forked. Scales large and uniform, pectinated and serrated, not deepened or thickened along the course of the lateral line.”

Identified by oilshale using Woodward, 1901.
