  We have performed high energy resolution angle-resolved photoemission studies
of the normal state band structure of oxygen overdoped
$Bi_{2}Sr_{2}Ca_{1}Cu_{2}O_{8+x}$. We find that there is an extended saddle
point singularity in the density of states along $\Gamma-\bar{M}-Z$ direction.
The data also indicate that there is an asymmetry in the Fermi surface for both
the $\Gamma-\bar{M}-Z$ and perpendicular directions.
