Lost River Island Purse/Wallet

Orange snakeskin wallet. Fairly bulky i reckon it was left on the 23 bus home from Busaras in Dublin last Tuesday night the 4th of November. Irreplaceable and urgent items included so i'm pretty desperate to find it. All help appreciated. Stations after I got off would've been Longford, Rooskey, Dromod, Collooney and Sligo. Have checked in all the stations so it'd be much appreciated if someone could help. Thanks
