I've just spent a frustrating few minutes trying to find a reference in BioStor. The reference in question is and comes from the Reptile Database page for the gecko Phyllodactylus gilberti HELLER, 1903. This is primary database for reptile taxonomy, and supplies the Catalogue of Life, which repeats this reference verbatim. Thing is, this reference doesn't exist! Page 39 of Proc. Biol. Soc.
