None. Cuvier begins his summary about Savigny on p. 176 thus (translated): "But one of the most surprising discoveries that have been made in zoology is that of the multiplicity of earthworm species, observed by Mr. Savigny. Who would have thought that animals so well known, that we trample on feet every day, and whose differences we had never suspected, offered such, however, only by limiting themselves to those around Paris, we could count up to twenty-two species? However, this multiplicity is today certain, according to the author; and since these species are all found in our gardens, and most of them are common there, ... Cuvier ends by writing: "This is the analysis of the work of M. Savigny, which we have believed to have to given with some extent because of interest that a series of such unexpected events cannot be missed to inspire all naturalists. It is important to remember each day how little we are little advanced in the study treasures of nature, and there were certainly never any more striking proof than this."
[ The species names briefly diagnosed by Cuvier (1826) in his precis of Savigny are:
Enterion terrestre, Enterion caliginosum, Enterion carneum, Enterion festivum, Enterion herculeum, Enterion tyrtaeum, Enterion castaneumm Enterion mammale, Enterion cyaneum, Enterion roseum, Enterion fetidum, Enterion rubidum, Enterion chloroticum, Enterion virescens, Enterion ictericum, Enterion opimum, Enterion octaedruni, Enterion pygmaeum, Enterion tetraedrum. It is not made clear which are new taxa. Possibly Cuvier did not know. However, at least E. terrestre and E. fetidum had been described earlier (Savigny, 1822)].
