IC 3057 may be ESO 267-G036, but that is well off Stewart's nominal position. Also, the galaxy is a low surface brightness, late-type spiral, while Stewart's description reads "cF, S, R neb or defect, susp." Finally, the Bruce plate was exposed for only one hour rather than the usual four hours for deep sky-limited plates at Arequipa.

So, IC 3057 is most likely, as Stewart suggested, a defect.
