The classification of Vertebrate and Invertebrate Animals was primarily due to Lamarck; but in his Système des animaux sans vertèbres, 1801, he does not use the word invertébrés, which occurs however in his Philosophie Zoologique of 1809; it had been used by Cuvier and Duméril in 1805 (Cuvier Leçons d'Anatomie compar. I, Table I), and by Duméril, in 1806, in his Zoologie analytique, 3, Table I.]
