The fifth list of objects of the Second Byurakan Spectral Sky Survey is given. It relates to the 40 x 40 region centered on the coordinates approx. = 15/sup h/30/sup m/, delta = +59/sup 0/00'. The observations were made with the 40-52'' Schmidt telescope of the Byurakan Astrophysical Observatory with a set of three objective prisms. The list contains data on 104 objects and galaxies having a peculiar physical nature and 11 blue stars. In this area there have been found 14 candidates for QSOs and four Seyfert galaxies, 24 BSOs, 27 galaxies with appreciable ultraviolet continuum, and 39 emission galaxies without appreciable ultraviolet continuum. The surface density of the QSOs and Seyfert galaxies in the investigated region down to the limiting magnitude 19/sup m/0 is more than one per square degree; the surface density of emission galaxies is more than four per square degree.
