He was taken to the house of Senor Francisco Galeochoa at Posedas, and was there discovered to have a tail ten inches long.

On interrogation the boy stated that he had a brother who had a tail as long as his own, and that all the tribe had tails.
Aetius, Bartholinus, Falk, Harvey, Kolping, Hesse, Paulinus, Strauss, and Wolff give descriptions of tails.

Blanchard says he saw a tail fully a span in length: and there is a description in 1690 of a man by the name of Emanuel Konig, a son of a doctor of laws who had a tail half a span long, which grew directly downward from the coccyx and was coiled on the perineum, causing much discomfort.

Jacob describes a pouch of skin resembling a tail which hung from the tip of the coccyx to the length of six inches.

It was removed and was found to be thicker than the thumb, consisted of distinctly jointed portions with synovial capsules.
