  This paper, pursuing the work started in [10] and [11], holds six new
formulae for {\pi}, see equations, through ratios of first kind elliptic
integrals and some values of hypergeometric functions of three or four
variables of Lauricella type. This will be accomplished by reducing some
hyperelliptic integrals to elliptic by the methods taught by Legendre in his
treatise. Eventually, evaluating some hyperelliptic integrals by means of
hypergeometric Lauricella functions, we obtain some further evaluations of
themselves in some particular points and also in their analytic continuation.
