The observational material consists of CCD images of four $36$ arcmin ${\\times} 36$ arcmin fields obtained with the MOSAIC II camera at the Blanco 4-m telescope at CTIO. Our present work supersedes previous Antlia studies in the sense that the covered area is four times larger, the limiting magnitude is $M_{B} {\\sim} -9.6$ mag, and the surface photometry parameters of each galaxy are derived from S\\'ersic model fits extrapolated to infinity.
