Summary G e n e r a l i z a t i o n s of the B a n a c h - S a k s p r o p e r t y were used by several authors to characterize reflexive Banach spaces (cf. [Ii~, [12~, and [16~). We give a c h a r a c t e r i z a t i o n of separable conjugate Banach spaces by a similar summability condition. As a consequence, we obtain analogous c h a r a c t e r i z a tions of separable second conjugate Banach spaces and of q u a s i - r e f l e x i v e spaces. N o n s e p a r a b l e conjugate Banach spaces p o s s e s s i n g a smooth predual are also c h a r a c t e r i z e d in terms of a s u m m a b i l i t y condition.
