This paper presents, in a compact and usable form, the body of known material on the diverse dialectical forms of the Karankawa Indians of coastal Texas, who have been extinct since the last of their number perished in the 1850s. John Reed Swanton (1940) published 5 of the 6 main sources in a Karankawa-English vocabulary, but his works omitted the most extensive vocabulary, collected by Rafael Chowell in 1828-29. The material includes a phonetic key, an English-Karankawa vocabulary list of several hundred words and expressions, authentic Karankawa texts and sentences, notes on Karankawa personal names, and an analysis of Joseph H. Greenberg's use of Karankawa in his book "Language in the Americas" (1987). Contains 30 references. (MDM)
