Amphibia the lungs on either side are still very simple transparent sacs with thin walls, as in the common water-salamander, the Triton. ❋ Ernst Heinrich Philipp August Haeckel (1876)

The lower or ventral wall of the flat dividing space (vw) is made up of larger and darker segmentation-cells; it corresponds to the lower or vegetal hemisphere of the blastula of the water-salamander (Figure 1.45 dz). ❋ Ernst Heinrich Philipp August Haeckel (1876)

Our common water-salamander (Triton taeniatus) is a particularly good subject for observation. ❋ Ernst Heinrich Philipp August Haeckel (1876)

Nature meant for a land-salamander into a water-salamander, with new rudder-tail and gills instead of lungs and feet suppressed, by feeding him with water animals in oxygenated water and cajoling his functions. ❋ Theodore Watts-Dunton (1873)

In the amphibia, also, especially the water-salamander (Triton), we can observe very clearly the articulation of the coelom-pouches and the rise of the primitive segments from their dorsal half (cf. Figure ❋ Ernst Heinrich Philipp August Haeckel (1876)
