Leuciaciis h<ilte((tii!f w^vvwds the tributai'ies of the I''ra/.cr and Cohnnbia as liioh 

 as the falls will permit. Xo oIIkm- species is found in the 1^'razer system nor in 

 the Coliiuibia b;isin pinper. The specimens from Brown's < iulch were described 

 as difl'eient from those of the lower ('ohnnl)ia. but a comparison of lar^'e numbers 

 from other localities has shown them to be but one of the numerous local \aria- 

 lions. Three other species, L. Iii/flrophlo.r, lineatus and alinar are found in the 

 Snake above the falls. The last two belon<;- to a diirerent section of the .<«enns 

 Leiici.<rus and are not closely related to balteuliix. All three have i)robabIy 

 enteri'd the Snake River from the Utah H.isin. As far as known the territories of 

 L. I>nltf(ttii.< and Inidiophlux do not overlap, unless those specinu'iis of h(illeutu.-< 

 with ojiiy 18 or 14 anal rays are in reality hijdrophiox, and as far as my e.xperienoe 

 soes, the nund)er of anal rays is the only ready means of distinijuishinn the two. 

 L Ixillidliis extends uji to or near to the lirst falls of the Snake, lii/droplihr. 

 is found from this ))oint to the lu'adwaters. A com[)arison of ht/ilrnphlo.r, bul- 

 todtii!' and (jiUi. the specimens from Brown's (iulch, makes it quite certain that 

 they are all modifications of the same form.
