A list of the principal stocks or families, tribes, and many sub-tribes of the North American Amerinds, based on the linguistic classification of the U. S. Bureau of Ethnology, as given in the _Seventh Annual Report_; on Brinton’s classification in his _The American Race_, on Mason’s “Linguistic Families of Mexico,” in the _American Anthropologist_, N. S., vol. ii., No. 1; in _Mexico_, Washington, 1900, Bureau of American Republics; Dall’s Tribes of the Extreme Northwest, _Contributions to North American Ethnology_, vol. i.; James Mooney’s _Siouan Tribes of the East_; and on lists in the _Bibliographies_ of James C. Pilling, with tribal names from other sources. +List of Stocks and Sub-Stocks+[408] The abbreviations are the ones used in the alphabetical list of tribes. By referring back from that list to this, the linguistic affinity and general geographical location of a tribe may be determined. The author has added the term “+Hopitan+” as a sub-stock of the +Shoshonean+ to designate the group of Hopi tribes, which, while showing strong linguistic affinity, are otherwise, like the +Piman+ and +Nahuatlan+, so markedly separated in habits from the true +Shoshonean+ stock that an individual classification for them seems desirable. As the +Hopitan+ are ranked as +Shoshonean+ in the general scheme the harmony of the classification is not interfered with. +Puebloan+ is also given as a comprehensive descriptive term for all the permanent house-building tribes, regardless of linguistic affinities, or ancient or modern existence. This is necessary because it is not possible to assign a linguistic place to the former occupants of ruins like those of the Chaco, yet it is settled that they were of a kind with the other town builders. Thus, also, the Cliff-dwellers may be conveniently classed under this head. Tusayan and Cibola, as applied respectively to the +Hopitan+ and the +Zuñian+, should never be used, for the reason that it is not certain that these are the places that were so designated by Coronado in 1540. The author believes they were not seen by Coronado.[409] It is in the interest of accuracy to avoid these unnecessary designations, which confuse ethnological and geographical matters. _Ada._ +Adaizan.+ Western Louisiana. _Alq._ +Algonquian.+ North-east third of the continent, from Tennessee and Montana. _Ath._ +Athapascan.+ North-west part of the continent, and from the Utah-Colorado line southward into Mexico. There are also some small groups on the Pacific coast in south-western Oregon and north-western California. _Att._ +Attacapan.+ Southern Louisiana. _Beo._ +Beothukan.+ Northern Newfoundland. Extinct. Formerly all Newfoundland. _Cad._ +Caddoan.+ Louisiana, Texas, Arkansas, and North Dakota. _Crb._ +Caribbean.+ Caribbean Islands and British Honduras. Also probably Florida and S. E. United States at a very early period.
