  Let $\gamma$ be a pseudo-Anosov homeomorphism and $X$ an element of the
Teichmuller space of a genus $g$ surface. In this paper, we find asymptotics
for the number of pseudo-Anosov homeomorphisms that are conjugate to $\gamma$
and the axis of their action on Teichmuller space intersects the ball of radius
$R$ centered at $X$, as $R$ tends to infinity.
