Abstract
In this article we further investigate the class (ZTR) of "zero-trace" quasidiagonal operators defined by D. A. Herrero in [Her 2]. Also, partial results are obtained towards answering the question of whether or not quasidiagonal quasinilpotent operators are limits of block-diagonal nilpotent operators.
