Lepidosiren

I fear it is a tadpole, but I keep the specimen lest it should be a Lepidosiren.

_Lepidosiren_, whose skeleton resembles the archetype in many ways, the pectoral girdle is likewise attached to the occipital segment.

Form and Function A Contribution to the History of Animal Morphology

_Lepidosiren_ in the river, and have heard of an electrical fish, I believe a _Malopteruris_, such as I formerly found.

Journal of the Proceedings of the Linnean Society - Vol. 3 Zoology Various

The fore-limb is a simple filament in _Lepidosiren_, and presents few joints in _Proteus_ and _Amphiuma_; in other air-breathing Vertebrates it shows

Form and Function A Contribution to the History of Animal Morphology

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 sundered in the natural scale.

IV. Natural Selection; or the Survival of the Fittest. Circumstances Favourable for the Production of New Forms Through Natural Selection 1909

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.

IV. Natural Selection; or the Survival of the Fittest. Summary of Chapter 1909

This remark no doubt must be restricted to those groups which have undergone much change in the course of geological ages; and it would be difficult to prove the truth of the proposition, for every now and then even a living animal, as the Lepidosiren, is discovered having affinities directed towards very distinct groups.

From these primitive fishes were evolved higher fishes of the ganoid type and others of the type of Lepidosiren

Evolution in Modern Thought Gustav Schwalbe 1880

This is confirmed by a number of interesting facts that have lately come to our knowledge in connection with the embryonic development of the Ceratodus and Lepidosiren; they give us important information as to the stem-history of the lower

There are only three genera of the class living to-day: Protopterus annectens in the rivers of tropical Africa (the White Nile, the Niger, Quelliman, etc.), Lepidosiren paradoxa in tropical South America (in the tributaries of the Amazon), and Ceratodus Forsteri in the rivers of
