Same entry in ps.-Zonaras. The headword, presumably extrtacted from the quotation given, is neuter singular of this adjective.
[1] Greek Anthology 6.223.1 (generally ascribed to Antipater of Sidon), a fisherman's dedication of a scolopendra that he found on a beach; cf. Gow and Page (vol. I, 28); (vol. II, 74-75); and further extracts from this epigram at gamma 456, epsilon 3049, omicron 521, pi 1426, and xi 15. For the creature in question -- a sort of maritime millipede -- cf. epsilon 37, kappa 2635, xi 15, sigma 646, and see generally LSJ s.v. Gow and Page note (vol. II, 75) that the headword adjective is not found elsewhere and that a(liplanh/s -- here in the epic/doric genitive singular -- is rare and, as instanced at Greek Anthology 11.390 (Lucillus), applies to sailing ships.
