The authors report IUE observations of five blue, low-metallicity, star-forming galaxies sufficiently redshifted to permit detection of Lyα. Two of the galaxies exhibit Lyα emission at modest levels far below the recombination limit; two objects have Lyα in absorption. These observations confirm and extend earlier work which indicates that relatively unevolved galaxies do not exhibit striking Lyα emission signatures, even when strong ultraviolet continuum emission from hot stellar populations is observed. The sample fo 13 blue galaxies observed with IUE shows an anti-correlation of Lyα emission with metallicity.
