We have discovered two new high redshift (z=2.38) galaxies, near thepreviously known z=2.38 galaxy 2139-4434 B1 (Francis et al. 1996). All three galaxies are strong Ly-alpha emitters, and have much reddercontinuum colors (I-K about 5) than other optically-selected high redshiftgalaxies. We hypothesize that these three galaxies are QSO IIs; radio-quietcounterparts of high redshift radio galaxies, containing concealed QSO nuclei.The red colors are most easily modelled by an old (> 0.5 Gyr), massive (> 10E11solar masses) stellar population. If true, this implies that at least onegalaxy cluster of mass much greater than 3E11 solar masses had collapsed beforeredshift five.Comment: 12 pages, 2 figures, uses aaspp4 style file. Accepted for publication in Astrophysical Journal Letter
