Same entry in other lexica (see the references at Photius mu248 Theodoridis), and in a scholion on Thucydides 1.86.2, where mellh/somen and me/llousi occur (in the short speech by the Spartan ephor Sthenelaidas). The present headword must be quoted from somewhere else; perhaps Demosthenes 54.40, though there are numerous other possibilities.
[1] Aorist participle of me/llw, masculine nominative singular; cf. epsilon 973, mu 538, mu 539.
[2] With single lambda, from me/lw: cf. mu 493, mu 539, mu 540.
