We partially generalize the results of Kudla and Rallis on the poles of
degenerate, Siegel-parabolic Eisenstein series to residual-data Eisenstein
series. In particular, for $a,b$ integers greater than 1, we show that poles of
the Eisenstein series induced from the Speh representation $\Delta(\tau,b)$ on
the Levi $\mathrm{GL}_{ab}$ of $\mathrm{Sp}_{2ab}$ are located in the "segment"
of half integers $X_{b}$ between a "right endpoint" and its negative, inclusive
of endpoints.
