  The Extended Chandra Deep Field-South (E-CDF-S) survey consists of 4 Chandra
ACIS-I pointings and covers ~1100 square arcminutes (~0.3 deg^2) centered on
the original CDF-S field to a depth of approximately 228 ks (PI: Niel Brandt;
Lehmer et al, 2005). This is the largest Chandra survey ever conducted at such
depth. In our analysis (Virani et al, 2005), we detect 651 unique sources --
587 using a conservative source detection limit and 64 using a lower source
detection limit. Of these 651 sources, 561 are detected in the full 0.5--8.0
keV band, 529 in the soft 0.5--2.0 keV band, and 335 in the hard 2.0--8.0 keV
band. For point sources near the aim point, the limiting fluxes are
approximately $1.7 \times 10^{-16}$ $\rm{erg cm^{-2} s^{-1}}$ and $3.9 \times
10^{-16}$ $\rm{erg cm^{-2} s^{-1}}$ in the 0.5--2.0 keV and 2.0--8.0 keV bands,
respectively. We present the optical properties of these X-ray sources,
specifically the R-band magnitude distribution and a preliminary spectroscopic
redshift distribution. One exciting result is the discovery of 7 new Extreme
X-ray-to-Optical flux ratio objects (EXOs) found in the E-CDF-S field.
