[1] The headword is dative plural, evidently quoted from somewhere (perhaps, but not necessarily, the second quotation here).
[2] Polybius fr. 162 Büttner-Wobst; quoted again at upsilon 299. For keletes (another type of ship), see kappa 1301. Büttner-Wobst notes (535) that Valesius (Henri de Valois 1603-1676) attributed this fragment to Polybius and that Schweighäuser thought the likely subject to be Philip V of Macedon (cf. OCD(4) p.1129). Walbank concurs (753) with Schweighäuser and further suggests that the time frame of the fragment could be the years 215-214 BCE, a period when many of Philip's movements remain unknown.
[3] Quotation unidentifiable (but perhaps, in view of the vocabulary, Polybius again).
