An alternative spelling to Cyprus, Ciprus, Chipre, Cipris, etc. It is one of two anglicized versions that I know of, and I can never remember which version is more accepted.
What's the other anglicized version? "Cyprus" is the only correct spelling, as far as I know, and I'm Greek. Or are you referring to the transliteration, "Kypros"? That's pretty much never used (same with "Hellas" for Greece).
