he name of a species of marsh fly. It was also the name
of the sixth ruler of Mexico (flor. about 1500), and doubtless of
other distinguished persons. See Ixtlilxochitl, _Historia
Chichimeca_, cap. 51.

AZCAPOTZALCO, 50, 51. An ancient town in the valley of Mexico, once
the capital city of the Tepanecas (q. v.). The word means "place of
the ant-hills," from _azcaputzalli_.

AZTECS, 25. A Nahuatl tribe who derived their name from their
mythical ancient home, Aztlan. The derivation is obscure, but
probably is from the same radical as _iztac_, white, and, therefore,
Father Duran was right in translating Aztlan, "place of whiteness,"
the reference being to the East, whence the Aztecs claim to have
come. See Duran, _Historia de las Indias_, cap. II.

CACAMATL, 94, 95. The reference appears to be to Cacamatzin (the
_Noble Sad One_, from _cacamaua_, fig. to be sad), last ruler of
Tezcuco, son and successor, in 1516, of Nezahualpilli. He was put to
death by Cortes.

CATOCIH, 89. A doubtful word, which may not be a proper name.

CHALCO, 16, 69, 95. A town and lake in the valley of Mexico. The
people were Nahuas and subject to Mexico. The word is probably
derived from _Challi_, with the postpos. _co_, meaning "at the mouth"
(of a river). See Buschmann, _Ueber die Aztekischen Ortsnamen_, s.
689, and comp. _Codex Ramirez_, p. 18.

CHIAPA, CHIAPANECA, 70, 71. The province and inhabitants of Chiapas,
in Southern Mexico. There were colonies of Nahuas in Chiapas, though
most of the natives spoke other tongues. The derivation is probably
from _chia_, a mucilaginous seed highly esteemed in Mexico.

CHICHIMECATL or CHICHIMECS, 88, 89, 91, 101. A rude hunting tribe,
speaking Nahuatl, who settled, in early times, in the valley of
Mexico. The name was said to be derived from _chichi_, a dog, on
account of their devotion to hunting (_Cod. Ramirez_). Others say it
was that of their first chieftain.

CHICOMOZTOC, 88, 89. "At the seven caves," the name of the mythical
locality from which the seven Nahuatl tribes derived their origin.
The _Codex Ramirez_ explains the seven caves to mean the seven houses
or lineages (totems) of which the nation consisted.

CHILILITLI, 36. Name of a tower of sacred import. It is apparently a
compound of _chia_ or _chielia_, to watch, and _tlilli_, blackness,
obscurity, hence "a night watch-tower." It was probably used for the
study of the sky at night.

CHIMALPOPOCA, 43. "The smoking shield," from _c
