Perfect middle/passive participles, in the masculine accusative singular or neuter nominative/accusative singular. Similar entry in other lexica; references at Photius sigma758, where Theodoridis registers the headword as, variously, suneirhme/non and (as here) sunh|rhme/non but is inclined to follow L. Dindorf in thinking it should be emended to suneilhme/non. (If so, perhaps [DW] quoted from Lucian, Imagines 9.)
