Pliny's Gaulish Rhaphius: Celtic confirmation?

Of the Chaus and Cephus.
THE Hind-wolfe, which some call Chaüs, and the Gaules were wont to name Rhaphius (resembling in some sort a wolfe with Leopards spots) were shewed first in the solemnitie of the games and plaies exhibited by Cn. Pompeius the Great. He also brought out of Æthyopia other beasts, named ***Cephi, whose fore-feet were like to mens hands, and the hinder feet and legges resembled those of a man. He was never seene afterwards at Rome.

This is in Pliny Elder's Natural History about the chaus, a dubious species of wild cat, fox or wolf. I'd like to know if there's some attested Celtic matching this name Rhaphius. This "leopard-spotted wolf" seems to be the lynx.

Thanking,
