Complete list of caste terms

After 9 years of working on records, I came across "coiota" for the first time today. Thanks to a Portuguese-language web site's footnote I now know that it means media-mestiza/media-india.

But I was surprised that it was so difficult to find the meaning online -- and that I could not find a complete list of all the different caste terms used in Mexico over the centuries.

Does anyone know if there is such a list online?
