cf. generally upsilon 689.
[1] The headword is an adjective in the feminine nominative singular: understand h(me/ra "day." It is presumably extracted from somewhere, or generated by an oblique case somewhere. (If the latter, perhaps the passage about to be quoted here, though there are numerous alternatives.) No precise equivalent for the glossing in other lexica.
[2] Quotation (transmitted, in Adler's, view, via the Excerpts made for Constantine Porphyrogenitus) unidentifiable.
[3] This looks like a shorter version of the quotation from Dionysius of Halicarnassus, Roman Antiquities 20.3.5, at upsilon 689.
