It has been proposed that spacetimes with a U(1) isometry group have
contributions to the entropy from Misner strings as well as from
the area of $d-2$ dimensional fixed point sets. In this paper we
test this proposal by constructing Taub-Nut-AdS and Taub-Bolt-AdS
solutions which are examples of a new class of asymptotically locally
anti-de Sitter spaces. We find that with the additional contribution
from the Misner strings, we exactly reproduce the entropy calculated
from the action by the usual thermodynamic relations. This entropy
has the right parameter dependence to agree with the entropy of a
conformal field theory on the boundary, which is a squashed three-sphere,
at least in the limit of large squashing. However the conformal field
theory and the normalisation of the entropy remain to be determined.
