merging) has occured (Schweizer et al. 1983, Whitmore et al. 1987). From the other side, recent simulations by Curir & Diaferio (1994) seem to indicate that a single dissipationless collapse of rotating triaxial system can produce misaligned spins.

Here we give the results of new observations of two candidates to PRGs from the PRC which obviously demonstrate the possibility of polar-ring galaxy formation as a result of interaction between galaxies.

Throught this paper the value $\rm H_{0}\,=\,$75 km/s/Mpc is adopted.

Observations and reductions
===========================

The photometric observations of galaxies were carried out in 1992 and 1994 in the prime focus of the 6-m telescope of the Special Astrophysical Observatory of Russian Academy of Sciences. The photon collector was virtual phase CCD of 520$\times$580 pixels, each 18$\times$24 $\mu$m (0.15$\times$0.2$\arcsec$) (Borisenko et al.1991). Reimaged optics, that realized a field of view $\rm 4.5\,\times\,6.9'$ with angular resolution $\rm 0.53\,\times\,0.71"$, was used during our observations of NGC 6286. Observations of NGC 3808 were obtained without reimaged optics $-$ with a field of view $\rm 1.3\,\times\,2.0'$ and resolution $\rm 0.15\,\times\,
0.2"$. The data were acquired with standard Johnson $B$, $V$ and Cousins $R$ filters for NGC 6286, and with Johnson $V$ and Cousins $R$, $I$
