He is most famous for his work in the areas of herpetology, malacology, and ichthyology.

In 1854 he graduated from the College d'Arras, followed by studies in medicine and zoology in Paris.

In 1861, he received his medical doctorate, then continued his zoological studies with Henri Milne-Edwards (1800–1885), earning his degree in natural sciences in 1865.

He held a special interest involving the systematics and anatomy of turtles and crocodiles, but also made significant contributions in his investigations of reptilian physiology and behavior.
