_Gros ventres_ is another of their designations; _Minetari of the Prairie_ another. This last is inconvenient, as well as incorrect, since the true _Minetari_ are a Sioux tribe, different in language, manners, and descent. _Arrapaho_ is a third synonym; and this is important, since there are other _Arrapahoes_ as far south as the Platte and Arkansas Rivers. The identity of name is _primâ facie_ evidence of two tribes so distant as those of Arkansas and the Saskatchewan being either offsets from one another, or else from some common stock; but it is not more. Nothing can be less conclusive. This has just been shown to be in the case of the term _Minetari_. The Ahnenin, or Atsina language is peculiar; though the confederacy to which the Indians who speak it belong, is the Blackfoot. Of the southern Arrapaho we have no vocabulary; neither do we know whether the name be native or not. * * * * * A tract still stands over for notice. As we have no exact northern limits for the Nehanni, no exact western ones for the Dahodinni, and no exact southern ones for the Loucheux, the parts due east of the Russian boundary are undescribed. I can only _contribute_ to the ethnology here. _The Ugalentses._--Round Mount St. Elias we have a population of _Ugalentses_ or Ugalyakhmutsi. Though said to consist of less than forty families,[76] as their manners are migratory, it is highly probable that some of them are British. _The Tshugatsi_.--In contact with the Ugalents, who are transitional between the true Eskimo and the true Kolúch, the Tshugatsi are unequivocally Eskimo. The parts about Prince William's Sound are their locality. _The Haidah._--Queen Charlotte's, and the southern extremity of the Prince of Wales' Archipelago, are the parts to which the Indians speaking the Haidah language have been referred. In case, however, any members of their family extend into the British territory, they are mentioned here. Three Haidah tribes are more particularly named-- _a._ The _Skittegat_. _b._ The _Cumshahas_--a name remarkably like that of the _Chimsheyan_, hereafter to be noticed. _c._ The _Kygani_. _The Tungaas._--This is the name of the language of the most Northern Indians, with which the Hudson's Bay Company comes in contact. It is Kolúch; and more Russian than British.
