  We show the manifolds at infinity of the complex hyperbolic triangle groups
$\Delta_{3,4,4;\infty}$ and $\Delta_{3,4,6;\infty}$,are one-cusped hyperbolic
3-manifolds $m038$ and $s090$ in the Snappy Census respectively.That is,these
two manifolds admit spherical CR uniformizations.
  Moreover, these two hyperbolic 3-manifolds above can be obtained by Dehn
surgeries on the first cusp of the two-cusped hyperbolic 3-manifold $m295$ in
the Snappy Census with slopes $2$ and $4$ respectively. In general,the main
result in this paper allow us to conjecture that the manifold at infinity of
the complex hyperbolic triangle group $\Delta_{3,4,n;\infty}$ is the one-cusped
hyperbolic 3-manifold obtained by Dehn surgery on the first cusp of $m295$ with
slope $n-2$.
