  At least one state in the first family of D-wave $b \bar b$ quarkonium levels
has been discovered near the predicted mass of 10.16 GeV/$c^2$. This state is
probably the one with J=2. This state and the ones with J=1 and J=3 may
contribute a detectable amount to the decay $\Upsilon(1D) \to \Upsilon(1S) \pi
\pi$, depending on the partial widths for these decays for which predictions
vary considerably. The prospects for detection of the chain $\Upsilon(3S) \to
\Upsilon(1D) + X \to \Upsilon \pi \pi + X$ are discussed.
