  We classify all the zeros and non-zero values of a family of hypergeometric
series in the $p$-adic setting. These values of hypergeometric series in the
$p$-adic setting lead to transformations of hypergeometric series in the
$p$-adic setting which can be described as $p$-adic analogues of Kummer's and
Pfaff's linear transformations on classical hypergeometric series. We also
evaluate certain summation identities for hypergeometric series in the $p$-adic
setting as well as Gaussian hypergeometric series.
