A pure excedance in a permutation $\pi=\pi_1\pi_2\ldots \pi_n$ is a position$i<\pi_i$ such that there is no $j<i$ with $i\leq \pi_j<\pi_i$. We present aone-to-one correspondence on the symmetric group that transports pureexcedances to descents of special kind. As a byproduct, we prove that thepopularity of pure excedances equals those of pure descents on permutations,while their distributions are different.
