  Using initial-state radiation events from a total integrated luminosity of
11.957 fb$^{-1}$ of $e^+e^-$ collision data collected at center-of-mass
energies between 3.773 and 4.258 GeV with the BESIII detector at BEPCII, the
cross section for the process $e^{+}e^{-}\rightarrow\Lambda\bar{\Lambda}$ is
measured in 16 $\Lambda\bar{\Lambda}$ invariant mass intervals from the
production threshold up to 3.00 GeV$/c^{2}$. The results are consistent with
previous results from BaBar and BESIII, but with better precision and with
narrower $\Lambda\bar{\Lambda}$ invariant mass intervals than BaBar.
