[68] Cope has proposed the names _Camerosaurus_, _Amphicœlias_, &c., for these problematical animals. Marsh names them _Titanosaurus_, _Atlantosaurus_, &c., while Owen holds that some of them at least are identical with his genus _Chondrosteosaurus_. Seeley and Hulke adopt the name _Ornithopsis_, and support Cope’s view of their nature. [69] _Ratitæ._ [70] Woodward in a recent paper refers to a still more curious resemblance of the Dinosaurs to the biped lizard of Australia (_Chlamydosaurus_), which runs on its hind limbs, and even perches on trees. [71] A poplar occurs in Greenland, in beds held to be Lower Cretaceous. [72] By some regarded as Upper Cretaceous. [73] First recognized in American Eocene by Newberry. [74] Described by La Harpe and Gaudin, and recently by Gardner. [75] Recent discoveries have since the publication of the first edition removed the Bovey Tracey beds from the Miocene to the Eocene.

[78] Gray’s reasoning is based on the extreme view of the Glacial period now prevalent in America, contrary, as it appears to me, to the actual facts; but with limitations it holds good on more moderate views as well.

[85] The actual reason for belief in the past existence of land in the basin of the Indian Ocean is found in the close relationship of forms of life found in Madagascar, Southern Asia, and Australia. [86] Traditions of this animal, a veritable primæval unicorn, are said still to exist in Siberia. [87] As, for instance, those of Cro-Magnon, and Mentone, and Engis.
