The higher figure came out a week after the kidnappings when the Borno state governor insisted a military escort take him to the town. Parents told the governor that officials would not listen to them when they drew up their list of names of missing children and the total reached 234.
The discrepancy in the figures could not immediately be resolved.
Security officials had warned Gov. Kashim Shettima that it was too dangerous for him to drive to Chibok, 130 kilometers (80 miles) from Maiduguri, the Borno state capital and birthplace of the Boko Haram terrorist network blamed for the abductions.
Twenty-eight pupils escaped from their captors between Tuesday and Friday. Then another 16 were found to be day scholars who had returned to their homes in Chibok before the attack. That left 85 missing students, according to school officials.
This latest confusion comes after the military had reported last week that all but eight of those abducted had been rescued but then retracted the claim the following day.
Parents and other town residents have joined the search for the students in the Sambisa Forest which borders Chibok town and is a known hideout for the militants.
The kidnappings are believed to have been carried out by Nigeria's Islamic extremist rebels, known as Boko Haram. Boko Haram the nickname means "Western education is sinful" is violently campaigning to establish an Islamic Shariah state in Nigeria, whose 170 million people are about half Muslim and half Christian.
