The Astor Library of New York has an incomplete copy of a work of Carriedo on Oajaca, with colored drawings by him,—unfinished. Copious notes by the author's own hand accompany the text. In historical questions Carriedo mostly follows and cites Burgoa.

Francisco Pimentel. "Cuadro descriptivó de las Lenguas Indígenas de México." (See Yucatan and Chiapas.)

Manuel Orozco y Berra. In "Geografia de las Lenguas."—Reference is made to a number of very important papers on Oajaca, the title of one, among others, "Estado que comprende el número de Parroquias de la Diócesis de Oajaca, con expresion de sus nombres, Estado ó Territorio en que están situadas, número de pueblos, &c., &c."

Further, certain official reports are quoted,—the originals of which are in the hands of my friend Sr J. G. Icazbalceta,—Sr Orozco mentions the following:

Pedro de Ledesma. "Relacion de Oajaca, por el alcalde...." 1579.

Hernando de Cervantes. "Relacion de Teotzacualco y Amoltepec...." 1580.

Augustin de Salazar. "Relacion del vicario de Chilapa."

Juan Lopez. "Relacion del Corregidor...." 1579.

Finally, I must call attention to a linguistical work, known to me only through Sr Orozco y Berra's citation, and through references given by Sr Pimentel—to wit:

Antonio de Los Reyes. "Arte en lengua mixteca." México, 1593.
