Unknown daffodil 2

Here is the second one. This one I think is a species, It grows on mass on the banks of the River Weaver in Cheshire, the storey goes that it was planted by the Romans 2000yrs while they hung out here for a few years. It is a delicate shade of yellow and is an enchanting little flower, does anyone have this growing near them and what is it? Looking at it I would say it’s related to N.bicolour in some way ! Any ideas!
