ABSTRACT
The structure of the gonad primordia is described in the embryos of three species of poeciliid fish. Prior to the sexualisation of the germ cells, a dimorphism exists based upon the gonadal somatic features. This serves as a basis for distinguishing between male and female specimens. Presumptive males are characterised by the presence in at least one of their gonad primordia of a conspicuous stalk whereas in presumptive females, a stalk is completely lacking.
