TUNICAS. _Original locality._--Opposite the mouth of the Red River. _Present locality._--Avoyelle, on the Red River. PACANAS. _Present locality._--West of the Mississippi. _Original locality._--West Florida. There is the special evidence of Dr. Sibley, the chief authority for the Indians west of the Mississippi, that the Humas, Tunicas, Biluxas, and Pascagoulas, each speak (or spoke) a different language. The tribes which now follow are considered by Dr. Sibley to be _indigenous_ to the country west of the Mississippi; those last-mentioned having moved thither from the present states of Mississippi, Alabama, and West Florida, within the memory of man, or at least within the period of authentic history. They chiefly lie to the east of the River Sabine; (_i.e._ between that river and the Mississippi), so as to belong to the original area of the United States, rather than to Texas, a distinction of importance; inasmuch as, whilst the ethnology of the parts which belonged to the United States in A. D. 1836,[128] is, comparatively speaking, well understood, that of Texas is still fragmentary and imperfect. As far, however, as the Sabine, Dr. Sibley is the chief first-hand authority. NATCHITOCHES. _Divisions._--1. Natchitoches. 2. Yatassis. _Numbers._--In 1836, about 150, together. _Language._--Stated by Dr. Sibley to be different from any other.--Gallatin, p. 116. ADAHI. _Conterminous_ with the Natchitoches and Yatassis. _Language._--Known by a vocabulary. With no particular, but with miscellaneous affinities.--Gallatin's Synopsis. _Numbers._--In 1836, about fifty. APELUSAS. _Numbers._--In 1836, about 40. Said by Dr. Sibley to speak a distinct language. _Locality._--The district so called. ATTACAPAS. _Numbers._--In 1836, about 50. Said to have been cannibals and flat-heads. _Language._--Known by a vocabulary. With no special but with miscellaneous affinities. _Divisions._--1, Attacapas; 2, Carankuas. At least this latter tribe, according to Dr. Sibley, speaks the same language with the Attacapas.--Gallatin, 116. Now if the Karanchuhuas of Texas be the Carankua Attacapas, the extension of that family is remarkable, since the locality of the Karanchuhuas is sea-coast about Matagorda Bay. Again,--the Cokes are a branch (extinct or nearly so) of the Karanchuhuas.
