We carried out a K′ band survey during August and September, 1994, in the south galactic pole region that covers 180.8 arcmin2 to K = 19 and 2.21 arcmin2 to K = 21 by the ANU 2.3 m telescope at SSO, Australia, equipped with PICNIC, developed at NAOJ. New galaxy number counts from K = 13 to 22 were obtained, which provided the best determination of the galaxy counts from K = 17.5 to 19.0 because of our large survey area. They were very consistent with Gardner, Cowie, & Wainscoat (1993, ApJL, 415, 9) and other observations to K < 19, however, they were larger than the galaxy counts of Saracco et al. (1997, AJ, 114, 887) with similar area and depth of survey around that magnitudes.
