Confusing sources of Seyferts and H II galaxies in the IRAS point source catalogue may be caused by companion objects of those galaxies. Comparison between confused galaxies and nonconfused galaxies have been made. The preliminary comparison shows that confused galaxies are fainter than nonconfused galaxies generally, and colour diagrams illustrate that confused Seyferts are separated from nonconfused Seyferts obviously. The redshift distribution histogram shows that the sample is not even at very small redshifts.
