  We compare the peculiar velocity field within 65 $h^{-1}$ Mpc predicted from
2MASS photometry and public redshift data to three independent peculiar
velocity surveys based on type Ia supernovae, surface brightness fluctuations
in ellipticals, and Tully-Fisher distances to spirals. The three peculiar
velocity samples are each in good agreement with the predicted velocities and
produce consistent results for $\beta_{K}=\Omega\sbr{m}^{0.6}/b_{K}$. Taken
together the best fit $\beta_{K} = 0.49 \pm 0.04$. We explore the effects of
morphology on the determination of $\beta$ by splitting the 2MASS sample into
E+S0 and S+Irr density fields and find both samples are equally good tracers of
the underlying dark matter distribution, but that early-types are more
clustered by a relative factor $b\sbr{E}/b\sbr{S} \sim 1.6$. The density
fluctuations of 2MASS galaxies in $8 h^{-1}$ Mpc spheres in the local volume is
found to be $\sigma\sbr{8,K} = 0.9$. From this result and our value of
$\beta_{K}$, we find $\sigma_8 (\Omega\sbr{m}/0.3)^{0.6} = 0.91\pm0.12$. This
is in excellent agreement with results from the IRAS redshift surveys, as well
as other cosmological probes. Combining the 2MASS and IRAS peculiar velocity
results yields $\sigma_8 (\Omega\sbr{m}^/0.3)^{0.6} = 0.85\pm0.05$.
