Abstract: A symbolic calculus for some algebras of Mellin operators on the finite interval $ J \equiv \left[ {0,1} \right]$ is developed. The algebras are ample enough to include singular integral operators and analytic double layer potentials and their adjoints on $ {C^1}$ curves and piecewise $ {C^1}$ curves with corners. Fredholmness and the index of the operators on $ {L^p}\left( J \right)$ are completely determined by the principal symbol on $ {L^p}\left( J \right),{\text{Smb}}{{\text{l}}^{1/p}}$.
