In the book of the twenty-fifth of the Association the editors made a mistake in attributing the photo published on page 52 which depicts the entrance of the Cueva de la Vuelta into the Rio la Venta on the day it was discovered and explored for the first time.

Rightly the author pointed this out to us and we want to give him credit. The photo was incorrectly attributed to Tullio Bernabei while the author is MARCO TOPANI.

We apologize.
