Another flower needing an ID!

[Printemps]

I've long lost the label for these and can't for the life of me remember what these flowers are called. I did wonder whether they might be fritillaria or nerines, but then thought better of my limited floral knowledge, so can anyone tell me what they are please?

Erythronium or Dog's tooth violet. I think.

Spot on Jeanied - thank you! I was a touch wide of the mark, putting it mildly lol!!
