William Herschel discovered NGC 3571 = H II-819 on 8 Mar 1790 (sweep 936) and reported "pF, pL, bM, iF." His position matches ESO 570-011 = PGC 34028.

Ormond Stone independently discovered the galaxy on 7 Jan 1886 at the Leander-McCormick Observatory. His rough position (nearest min of RA) for NGC 3544 = LM 1-184 is two tmin too far west, but his description matches. So, NGC 3571 = NGC 3544. The primary designation should be NGC 3571, although RC3 labels this galaxy NGC 3544.

400/500mm - 17.5" (1/31/87): fairly faint, moderately large. Contains a small bright core surrounded by a faint halo elongated 2:1 ~E-W. Located 19' NW of mag 6.1 Psi Crateris.
