Summary:
Reptile genera in JH's [Physical Geography ] are consistent with those of [Edward] Forbes cited in Johnston's Physical Atlas [1854], but new genera have been discovered. Questions JH's claim that Elgin sandstone is Devonian. Notes Richard Owen's estimates on pterodactyl size, and distinct tail feathers [illustration] on recent specimen from Bavaria. Corrects JH's names for beaver genera.
