DeLisle Stewart found IC 4455 = D.S. 410 on an Arequipa plate taken in Jul 1899. There is nothing at Stewart's reported position, but 0.8 minutes of RA west and 3' N is NGC 5664, which also has a poor position (see that number). Due to the discrepancy in position, Dreyer assumed Stewart's object was new, but his comment "considerably elongated [in PA] 30°" clinches the identification IC 4455 = NGC 5664. MCG labels this galaxy as IC 4455.

400/500mm - 17.5" faint, small, elongated 5:3 SSW-NNE, 0.5'x0.3'. A mag 14.5 star is close SE. A tight knot of 4 or 5 mag 13-15 stars within 45" lies 10' SSW. Located 4.5° NE of Zubenelgenubi.
