That Extra Race

[Aiwendil]

I think it should be noted that the quote:

many of those lesser Vali who loved them and played nigh them and attuned their music to theirs, and these are the Mánir and the Sùruli, the slyphs of the air and the winds

appears to be from an early version of the Silmarillion (note 'Vali' rather than 'Valar'). I'm pretty sure that in later versions, the Manir and Suruli are not mentioned.
