Abstract : In this paper, we introduce and investigate two new subclasses of the function class of - - - spirallike functions defined in the open unit disc. Furthermore, We find estimates on the coefficients for functions in these two new subclasses for functions.

Keywords : Univalent Functions, -Univalent Functions, - -Spirallike, Subordination, Coefficients Bounds.
