[207] ἁλοσύδνης, a word recurring only Od. 4.404 “φῶκαι νέποδες καλῆς ἁλοσύδνης”, a passage which throws no light on the present. Hesych. has “ὕδναι: ἔγγονοι”, but that is probably only an attempt to explain the word, which was presumably written as two, “ἁλὸς ὕδνης”. It was, however, accepted in Alexandrian times, as Kallim. has “῾γδατοσύδνη” as the name of a Nereid. It is possible that -“υδν”may be the same as the stem “υδα-τ” for “υδν-τ” (G. Meyer Gr. § 335). The word will then mean ‘daughter of the saltwater,’ the patronymic force residing only in the noun-termination -“η”.
