Having reached the River Sabine, we may look both west and east. Eastward the question lies as to the extent to which the present list has been exhaustive--if not of individual tribes, at least of families and groups. Now the Creeks and Choctahs have been tribes of an _encroaching_ area; whilst as special fact, we find that in A.D. 1763, the Colooses retreated before the Creeks: first to the extremity of Florida, and afterwards to the Havannah. Upon good grounds, then, it has been believed that the natives of Florida, anterior to the spread of the Creeks, were other than Creek or Choctah. Into how many divisions this Floridian population fell, and amongst what known families (if any) it was divided, is unascertained. It might be one. It might be distributable amongst many--Uché, Catawba, Natchez, &c. It might, too, be represented by a wholly extinct family. Probably it was Uché on the south-west, and Catawba on the north. The Yamassis may have been the latter, the Colooses the former. Still the question is wholly open. Westward we come to Texas. Now the imperfect and fragmentary character of our information makes the consideration of the Texian Indians (known by little beyond their names) most conveniently follow the enumeration of the tribes to the north and west of them--besides which, four unplaced families have still to be enumerated as belonging to, and interrupting the great Algonkin and Sioux areas. THE AHNENIN. _Synonym._--Arrapahoes(?)--Fall Indians, from their locality. _Locality._--The Falls of the River Saskatchewan. _Language._--Peculiar. ARRAPAHOES. A tribe of this name is placed in Mr. Catlin's map, in California, on one of the eastern feeders of the Colorado, in the latitude of Santa Fé. The Arrapahoes, again, according to Gallatin, are a detached tribe of the Ahnenin, who have wandered as far south as the Platte and Arkansas Rivers. The identity, when ascertained, of name, is _primâ facie_ of this. Still it is not much more. On the other hand the fact is by no means improbable. A vocabulary of the southern Arrapahoes has yet to be collected. RICCAREES. _Locality._--The Missouri, about 150 miles below the Mandans. The Riccarees have been classed in the section next following. The scanty vocabulary, however, of the two languages, by no means justifies us in making this affinity a very close one. On the other hand, they are kept distinct in the present work, provisionally. PAWNEES (PANIS). _Locality._---Valley of River Platte, extending as far west as its sources, and as far south as the Arkansas. _Divisions._--_a._ The Loup Pawnees. _b._ The Republican Pawnees. The Towiatch[129] of Texas are also called Pawnees; probably improperly. * * * * *
