A species iiUied to the preceding, described as follows: " The body is slender, tail greatly attenuated, head constituting something more than one-lifth of the total length. Eye rather small, subelliptical, its diam- eter (5^ times in the entire length of the head. The posterior extremity of the maxilltiry extends to a vertical line drawn posteriorly to the an- terior edge of the orbit. Anterior margin of the dorsal fin nearer the base of the caudal than the extremity of the snout. Anterior margins of the ventral (ins somewhat nearer the extremity of the snout than the base of the caudal. The lateral line is nearly concurrent with the ven- tral outline. The numbers of the fln-rays are: D. 10; P. 10; V. 8; A. l);C. ; {Abbott.) Dull violet above, pinkish below. Kansas Hiver; Platie River. (We have some time since examined specimens from Platte River, and thought them distinct from 0. robusta and G. grahami, but iiaving lost our notes are unable to add to Dr. Abbott's account.)

Head large, its upper pro- file not very strongly concave. Mouth large, terminal and oblique, the upper jaw scarcely longer than the lower, maxillary reaching past the frout of the eye. Interorbital space broad. Pectorals falling consid- era
