And it is in fresh water that we find seven genera of Ganoid fishes, remnants of a once preponderant order: and in fresh water we find some of the most anomalous forms now known in the world, as the Ornithorhynchus and Lepidosiren, which, like fossils, connect to a certain extent orders now widely separated in the natural scale.
The genera Ornithorhynchus and Lepidosiren, for example, would not have been less aberrant had each been represented by a dozen species instead of by a single one; but such richness in species, as I find after some investigation, does not commonly fall to the lot of aberrant genera.
As we here and there see a thin, straggling branch springing from a fork low down in a tree, and which by some chance has been favoured and is still alive on its summit, so we occasionally see an animal like the Ornithorhynchus or Lepidosiren, which in some small degree connects by its affinities two large branches of life, and which has apparently been saved from fatal competition by having inhabited a protected station.
"I didn't mean an altogether animal, or even a bird, but any a a a ." She seemed puzzled how to speak of the Platypus, when the strange creature, seeing the well-meaning embarrassment of the Kangaroo, said affably, "any mammal or Ornithorhynchus Paradoxus." "Exactly," said the Kangaroo, brightening up, although she hadn't the least idea what a mammal was.
Even in Australia itself the ornithorhynchus and echidna have had to put up perforce with the lower places in the hierarchy of nature.
And it is in fresh water basins that we find seven genera of Ganoid fishes, remnants of a once preponderant order: and in fresh water we find some of the most anomalous forms now known in the world, as the Ornithorhynchus and Lepidosiren, which, like fossils, connect to a certain extent orders at present widely separated in the natural scale.
