摘要：

We present a search for neutral hydrogen (HI) emission from optically identified dwarf galaxy candidates in the larger M 81 group area. Of 136 candidates, 68 galax ies have been detected (this corresponds to a detection rate of similar to 49%). Most of the detected galaxies are background objects and fail to be classified as dwarfs. Many known dwarfs in the M81 group have been detected, but no new members have been discovered.
