Let D be a commutative integral domain with 1. An element x ED is called primal if xlab implies that x= rs where rla and slb. An integrally closed integral domain D is called a Schreier domain if every element of D is primal. We call D pre-Schreier if every element of D is primal. Schreier domains were introduced by Cohn [5]-and what we call pre-Schreier domains, have featured in [? I and in several other papers (cf. eg [6] and [131). Along with several other characterizations of pre-Schreier domains we show that D is a pre-Schreier domain if and only if for al, a2, bl, b2 ED, ab lx implies that x= rs where a. lr and b. ls
