What is the eighth multiple intelligence which was not discussed in our lecture

The theory of multiple intelligences was first proposed by Howard Gardner in 1983 on his book Frames of Mind: The Theory of Multiple Intelligences. In this book, he broke intelligence down into eight categories. The modalities are:
1) Musical-rhythmic and harmonic
2) Visual-Spatial
3) verbal (linguistic)
4) logical mathematial
5) Kinesthetics
6) interpersonal
7) intrapersonal
8) naturalistic
9) existential

Not to mention in a recent interview Gardner is considering adding on the modality of teaching pedagogical as the last modality.
