Same or similar entry (from Aelius Dionysius) elsewhere; references at Photius omicron62 Theodoridis. The headword is the feminine nominative plural, presumably quoted from somewhere (though not necessarily in the nominative), of the adjective o)/i+os "of sheep," used (apparently) to refer to sheepskins.
For the first gloss, see delta 1290; for the second, mu 941.
