These galaxies are a pair lying at northern field of Sextans. A left one(eastern galaxy) is NGC3169 and a right galaxy (western one) is NGC3166, two galaxies are about 7 arc minutes apart. Both galaxies are compact spirals having diameters of 5 arc minutes and 11th magnitude. You can observe those only as very dimmed lumps of light through telescopes. This image shows you a slant dark lane in eastern NGC3169.
