They are not wholly herbivorous; for though they nibble the fronds of Riccia and threads of Conferva, they do not scruple to eat their dead kindred, and half a dozen may be seen engaged upon the carcase of a defunct brother. In this stage the gills form a fine microscopic object. As the “ tad ” increases in bulk, the hinder part of the body swells, and at last the budding of the hind legs may be distinctly seen. These at last acquire some degree of completeness, and then the other
pair of legs sprout in a similar manner, and the tail begins to shrink rapidly as the general bulk of the reptile increases.
