Narrative:

After landing on and clearing runway 31L we turned right onto taxiway J and held short of runway 31R. We requested clearance to taxi. The controller cleared us to taxi via taxiway C and to hold short of runway 31R at taxiway B. Taxiway C lies between and parallel to runways 31L and 31R. On taxiway J we were already past the taxiway signage for taxiway C and could not turn around to get back to taxiway C without crossing the runway 31R hold short line on taxiway J. I was confused as to the exact location of taxiway C since we were already beyond the signage for taxiway C. I was under the (mistaken) impression that taxiway C was still in front of us and I indicated to my copilot to continue straight ahead to reach taxiway C. It was at this point the ground controller indicated that we were not cleared across runway 31R and that we should stop immediately. We did stop and the airplane had crossed the hold short line; but did not enter the runway.
