Yes. In the Sarcopterygii, owls.

(Sorry, Ken, but you set yourself up for that one.

I do want to say that I value your attention to these features, and I'd 
be interested in your take on the presence/absence of eccrine glands on 
most body surfaces of mammals. Dogs have eccrine glands more or less 
restricted to the feet, iirc, but humans and horses have them over the 
entire body surface.)
