But here a discrepancy presents itself in the Iroquois system, which has perplexed all who have written on the subject. Two of the Six Nations, the Caniengas and Oneidas, had only three clans, the Wolf, the Tortoise and the Bear; while the others had, or at least have, each eight or nine, and these variously styled in the different nations. The three which have been named are, indeed, found in all; but besides these three, the Onondagas have five, Deer, Eel, Beaver, Ball and Snipe. The Cayugas and Senecas have also eight clans, which are similar to those of the Onondagas, except that among the Cayugas the Ball clan is replaced by the Hawk, and among the Senecas both Ball and Eel disappear, and are replaced by Hawk and Heron. The Tuscaroras have likewise eight clans, but among these are neither the Hawk, the Heron or the Ball. In lieu of them the Wolf clan is divided into two, the Gray Wolf and the Yellow Wolf, and the Tortoise furnishes two, the Great Tortoise and the Little Tortoise; [Footnote: It is deserving of notice that this division of the Tortoise clan seems to exist in a nascent form among the Onondagas. The name of this clan is Hahnowa, which is the general word for tortoise; but the clan is divided into two septs or subdivisions, the Hanyatengona, or Great Tortoise, and the Nikahnowaksa, or Little Tortoise, which together are held to constitute but one clan. How or why the distinction is kept up I did not learn. In the Book of Rites the Tortoise clan is also spoken of in the dual number--"the two clans of the Tortoise." It is probable, therefore, that this partial subdivision extended throughout the original Five Nations, and became complete among the Tuscaroras.] the Bear, the Beaver, the Eel and the Snipe remain, as among the Onondagas, Cayugas and Senecas.
