Three varieties of some importance have been indicated, Salmo irideus stonei, the Nissui trout of the Klamath, with spots on the posterior parts only, Salmo irideus shasta of the upper Sacramento, and the small-scaled Salmo irideus gilberti of the Kings and Kern rivers. In the head-waters of the Kern, in a stream called Volcano Creek or Whitney Creek, the waterfall some- times called Agua-Bonita shuts ofE the movements of the trout. Above this fall is a dwarf form with bright golden fins, and the scales scarcely imbricated. This is the "golden trout of Mount Whitney," Salmo irideus agua-honita.
