[1] Cratinus fr. 214 Kock, now 221 Kassel-Austin. On Cratinus see generally OCD(4) s.v. (p.391), and kappa 2344. His Seriphians dealt with the arrival of Perseus and Danae in their chest onto the shore of the island of Seriphos; Strabo 10.5.10 (C487) conveniently summarizes the myth as a whole. (A lost satyr play of Aeschylus, Dictyulci or Net-Draggers, apparently had much the same plot.) "Squeezers" or "drainers" are explained by Photius (Lexicon alpha1233) and Eustathius on the Iliad, p. 838.54, as men who inflict outrages on the common weal.
[2] The lexicographer is clearly correct about the occurrence of apheresis in the last two examples, but the principal case is more ambiguous: morgo/s has no literary attestations but occurs only in commentators or scholiasts. Both Photius, Lexicon alpha1235 Theodoridis, and Eustathius on the Odyssey p. 1608, 57 agree with the Suda, perhaps drawing on some lost scholiast. For asphodel, see alpha 4298, alpha 4299, sigma 1751; for a)mauro/s see alpha 1511, mu 295.
