1886 W. Pepper et al. Syst. Pract. Med. IV. 257 I think this pressure often inaugurates a retromorphosis that results in the final disappearance of the tumor.

1961 R. E. Snodgrass in Trans. Amer. Entomol. Soc. 87 279 The apparent metamorphosis of the larva into the imago, therefore, is simply the return to the parental form accompanied by the discarding of the specialized larval structures.

1996 Tectonophysics 260 122/1 It develops And–Cd–Ch or Sill–Mu paragenesis with retromorphosis of kyanite in sillimanite.
