In Eq. 5, the factor of $(p_\perp-p_\par)$ should be $(p_\par-p_\perp)$.

Right after Eq. 33, in the expression for $r_{\par,\par,0s}$, the pressure
$p_{\par 0s}$ should be squared. Likewise, on the next line, in the
expression for $r_{\perp,\perp 0 s}$, the factor of $p_{\perp 0s}$ should
also be squared. (Found by Prateek Sharma.)

On p.3980, 2 lines above Eq. 44, and on p.3981, 3 lines below the first
unnumbered displayed equation, a coefficient of 2 on the bb component of
the stress tensor should be replaced by a factor of 3, which is of course
required to insure that the stress tensor is traceless.

2009.08.27: On p. 3980, the first term on the 2cd line of Eq. 45, which
reads
-3 q_{\perp s} \grad \cdot \vec U
is wrong (it is dimensionally incorrect in this equation as it stands).
The "U" should be replaced with "b" so that it reads:
-3 q_{\perp s} \grad \cdot \vec b
(Thanks to Alex Schekochihin for point this out.)

A recent paper by J. Ramos (Phys. Plasmas 10, 3601 (2003)) derives a
similar set of fluid moment equations as derived in Snyder et al. Ramos
does this by first taking moments of the full Vlasov-Boltzmann equation,
and then doing an MHD-like low-frequency (omega<
