NGC 4960 is probably NGC 4961 with a 15 arcmin error in the declination. D'A saw N4960 only once, on a night when he did not record N4961 (he observed that on four other nights). The descriptions and RA's match, too. D'A also leaves us a brief note: "Nebula indubie visa, etiamsi locus confirmatione adhuc indigebit." This seems to be saying that while the nebula was certainly seen, there could be some doubt about its position.
Since there is nothing else obvious nearby that might be N4960, I'm going with N4961 for the time being.
The RNGC (Sulentic and Tifft 1973) notes that this is a galaxy. Their coded description reads ALMSTEL.
