Abstract: The purpose of this note is two-fold: (1) To point out that Stampfli's characterization of subnormal shifts can be reformulated in operator form which turns out to be the Spitkovskii's characterization of subnormal operators; (2) To use this reformulation to give a new proof of the subnormality of a class of shifts.
