In two previous notes I have given the various types of non-singular surfaces with sectional genera 4 and 5. In this paper the methods previously adopted are applied to the non-singular surfaces of sectional genus 6. For purposes of classification these may be divided into the four classes:
(1) Regular, non-rational.
(2) Rational.
(3) Irregular, non-referable.
(4) Referable.
