Suppose that M is a hyperbolic 3‐manifold which admits two Dehn fillings M ( r 1 ) and M ( r 2 ) such that M ( r 1 ) contains an essential annulus, and M ( r 2 ) contains an essential torus. It is known that Δ = Δ ( r 1 , r 2 ) ⩽ 5. We will show that if Δ = 5 then M is the Whitehead sister link exterior, and if Δ = 4 then M is the exterior of either the Whitehead link or the 2‐bridge link associated to the rational number 3 10 . There are infinitely many examples with Δ = 3. 1991 Mathematics Subject Classification : 11D25, 11G05, 14G05.
