[1] Same entry in the Synagoge (tau53) and Photius (tau101 Theodoridis), similar one elsewhere. The perfect active participle of qa/llw, masculine accusative singular or neuter nominative/accusative plural, is glossed with the present participle (corresponding part) of the same verb. The headword must be quoted from somewhere (other than the quotation given here); there are numerous possibilities.
[2] Quotation (transmitted, in Adler's view, via the Excerpta Constantini Porphyrogeniti) unidentifiable. (Adler notes Valckenaer's attribution of it to Aelian.)
