The Grass Valley speckled dace (Rhinichthys osculus reliquus) occurred in a single spring-fed creek in a grassy meadow in eastern Lander County, Nevada. Specimens were collected only once in 1938, and it was then considered common.[1] The species had a distinctive speckled lower lip and silver sided body. The introduction of brook and rainbow trout to the creek is believed to be the reason for their extinction.[1]
