Two 5 square degree regions around the NGC 7332/9 galaxy pair and theisolated galaxy NGC 1156 have been mapped in the 21-cm line of neutral hydrogen(HI) with the Arecibo L-band Feed Array out to a redshift of ~0.065$ (~20,000$km/s) as part of the Arecibo Galaxy Environment Survey. One of the aims of thissurvey is to investigate the environment of galaxies by identifying dwarfcompanions and interaction remnants; both of these areas provide the potentialfor such discoveries. The neutral hydrogen observations were complemented byoptical and radio follow-up observations with a number of telescopes. A totalof 87 galaxies were found, of which 39 (45 per cent) were previously catalogedand 15 (17 per cent) have prior redshifts. Two dwarf galaxies have beendiscovered in the NGC 7332 group and a single dwarf galaxy in the vicinity NGC1156 . A parallel optical search of the area revealed one further possibledwarf galaxy near NGC 7332.
