[1] The headword is dative plural of this present middle/passive participle, presumably extracted from the quotation given. The verb e)mfalko/omai is otherwise unattested. LSJ s.v. gives no translation for it but does have a cross-reference under the noun fa/lkhs, 'part of a ship, rib'.
[2] Quotation (also in ps.-Zonaras) unidentifiable. This fragment is also Polybius fr. 136 Büttner-Wobst. Büttner-Wobst notes (532) that Valesius (Henri de Valois 1603-1676) attributed the fragment to Polybius. However, Schweighäuser rejected it, and Büttner-Wobst agrees that the fragment is unlikely to be Polybian (ibid.).
[3] For which cf. generally kappa 2432, kappa 2434.
