  We extend the investigation of nonextremal enhancons, finding the most
general solutions with the correct symmetry and charges. There are two families
of solutions. One of these contains a solution with a regular horizon found
previously; this previous example is shown to be the unique solution with a
regular horizon. The other family generalises a previous nonextreme extension
of the enhancon, producing solutions with shells which satisfy the weak energy
condition. We argue that identifying a unique solution with a shell requires
input beyond supergravity.
