We thank Professor B.A.F. Wehrfritz for pointing out that the main Theorem 1.5 of [2] is incorrect. The first two authors showed in [1] that the quotient G/H of the periodic linear groupG in characteristic p remains p-linear provided the unipotent radical of G is trivial. The paper [2] sought a converse, asking: if G/H and H are both p-linear with finite unipotent radical, then when must G also be p-linear? As Professor Wehrfritz noted, the further condition assumed in [2], that the Hirsch-Plotkin radical of H is C̆ernikov, is not sufficient. A correct result with a similar proof is: Theorem. Let H be a normal subgroup of G and assume that (a) G/H is a periodic p-linear group with finite unipotent radical; (b) H is a periodic p-linear group...
