$\sharp$ -- Heavy-element line in the \Lya\ forest region of the spectrum;  
$\ddag$ -- line blended by identified line (\OI\ line is blended by
\CIV\ from System J);\\ 
$\dag$ -- line is probably blended with an unidentified line; 
\P\ -- saturated line;  
(a) -- detected in the MMT spectrum, but not seen in the Keck spectrum;\\ 
(b) -- detected in the MMT spectrum, but noise is too strong in
order to fit this line in the Keck spectrum.
