We present single-dish Lovell telescope HI observations of a sample of 67 emission-line and UV-excess galaxies, of which 52 are taken from the University of Michigan (UM) catalogue. In addition, HI observations of 24 gas-rich irregular galaxies are presented. We find that emission-line galaxies are Hi-rich with a median HI mass to blue luminosity ratio M_HI/L_B of ∼0.45M_☉/L_☉. Within the UM galaxy sample the M_HI/L_B ratio tends to increase with decreasing luminosity. Finally, it is found that the most Hi-rich UM galaxies are the most metal deficient, implying that these objects are less evolved.
