One of the aims of this survey is to investigate the environment of galaxies by identifying dwarf companions and interaction remnants; both of these areas provide the potential for such discoveries. The neutral hydrogen observations were complemented by optical and radio follow-up observations with a number of telescopes. A total of 87 galaxies were found, of which 39 (45%) were previously catalogued and 15 (17%) have prior redshifts. Two dwarf galaxies have been discovered in the NGC 7332 group and a single dwarf galaxy in the vicinity of NGC 1156. A parallel optical search of the area revealed one further possible dwarf galaxy near NGC 7332. Description: The HI survey observations of the NGC 1156 region were carried out using the 305m telescope at Arecibo Observatory between 2005 December and 2006 February and those of the NGC 7332 region between 2006 July and September. Both sets of observations used the Arecibo L-band Feed Array multibeam system and the fixed-azimuth drift observing mode to reach an integration time of around 300s/point. File Summary:

Note (1): Measured as the mid-point of the H i profile at 50% of the peak flux. Note (2): The velocity widths are not corrected for instrumental broadening, turbulent motions, disc inclination or cosmological effects. Note (3): Object flags, defined as follows: 0 = source securely detected in the survey data 1 = source confirmed by follow-up observations 2 = source contaminated by RFI (none of the sources in the regions reported in this paper have this flag) 3 = marks extended sources, measured as described in Section 2.1.
