In 1828, a scientific commission was created to accompany an expeditionary force to the Peloponnesus, sent as a mediation army between the Greeks and the Ottomans. This commission, originally conceived on the model of the Commission to Egypt that accompanied Bonaparte's forces, was to be more modest. The Cybèle, commanded by Marie Antoine Chevalier de Robillard, left on 10 February 1829. On board were three zoologists, Gaspard Auguste Brulle, Sextius Delaunay and Pector, the botanist J. Mary Despréaux, the geologist Pierre Théodore Virlet d'Aoust, and the artist Prosper Baccauet all under the direction of Jean Baptiste Georges Bory de Saint-Vincent. For several months, these naturalists combed the Peloponnesus and brought back a harvest of samples for the Museum, including fishes. Several fishes were described by Valenciennes in the 'Histoire naturelle des poissons'. Gabriel Bibron and J.B.G. Bory de Saint-Vincent also wrote about fishes in the third volume of the report of the scientific expedition to Morea (see Bauchot et al. 1990).
