Narrative:

Air carrier X cleared the runway. After landing ground cleared us to taxi to the ramp via charlie 7, cross 31, enter tango 4. We (the captain and I) cleared by looking out each side prior to entering runway 31. We were 3/4 the way across when an aircraft Y flew right over the top. He wasn't called or pointed out. We were cleared across the runway he was using. Apparently local and ground weren't talking to each other.
