Answer:
They are the gifts listed in Romans 7 and they are granted to believers by the indwelling Holy Spirit. Each believer has one gift given to him to use for the glory of God.
First Corinthians 12 is a list of gifts that are manifestations of the Holy Spirit and a believer may receive the work of the Spirit in any one of those areas at different times but they are not "possessed" by the believer like the gifts in Romans 12. Then you have the office gifts of the Holy Spirit given to the church in Ephesians 4.
