The natural history of fishes, amphibians, & reptiles, or monocardian animals . maybe conveniently divided, observes Cuvier, by a re-gard to the position of their ventral fins, which areeither situated behind the abdomen, as in the Abdo-minales; sometimes placed adjoining the shoulder, as inthe Subbrachiati j or altogether wanting, as in the Apodes(Linn.). It is impossible, however, as Cuvier thinks, to apply this mode of division to the Acanthopte-rygii; and their subdivision in any other way than bythat of natural families is a problem that I have hithertovainly endeavoured to solve.

The natural history of fishes, amphibians, & reptiles, or monocardian animals . maybe conveniently divided, observes Cuvier, by a re-gard to the position of their ventral fins, which areeither situated behind the abdomen, as in the Abdo-minales; sometimes placed adjoining the shoulder, as inthe Subbrachiati j or altogether wanting, as in the Apodes(Linn.). It is impossible, however, as Cuvier thinks, to apply this mode of division to the Acanthopte-rygii; and their subdivision in any other way than bythat of natural families is a problem that I have hithertovainly endeavoured to solve. Fortunately, many of thesefamilies are possessed of characters nearly as exact asthose that could be given to orders. (78.) ^Ye shall first concentrate the foregoing out-lines of Cuviers system in the following table, and thenproceed to enumerate more particularly the genera com-prised in the families.
