Long-slit observations of 4 dwarf spheroidal galaxies in the M 81 group are presented. We have obtained the heliocentric velocity of a globular cluster candidate located near the center of DDO 78 to be $55 \pm 10 \mathrm{km} \mathrm{s}^{-1}$ by cross-correlation with template stars. We estimated a heliocentric radial velocity of $-116 \pm 21 \mathrm{km} \mathrm{s}^{-1}$ for an HII region seen in K 61. A red diffuse object near the K 64 center is found to be a remote galaxy with a heliocentric velocity of +46 530 km s-1.
