d0245+3955 Irregular galaxy of low surface brightness form a tight triple d0245+3955 sub-system inside the NGC 1023 group. d0245+3957 Irregular galaxy of low surface brightness form a tight triple d0245+3957 sub-system inside the NGC 1023 group. d0246+3952 Irregular galaxy of low surface brightness form a tight triple d0246+3952 sub-system inside the NGC 1023 group. d0946+6842 This faint object of very low surface brightness was discovered by d0946+6842 Chiboucas et al. (2009AJ....137.3009C) as a probable background d0946+6842 galaxy behind the M 81 group. There is a strong disagreement d0946+6842 between its low luminosity and the broad HI line width, leading to d0946+6842 M_T_/L_B_~184 and M_HI_/L_B_=30 in solar units. We carefully d0946+6842 inspected its surroundings using POSS-II and SDSS and did not find d0946+6842 any suitable optical counterpart to explain the detected HI signal. d0946+6842 This object would be an interesting target for a more detailed d0946+6842 study. FS 20 = LeG 19 and LeG 18. These dwarf members of the Leo-I group FS 20 (Karachentsev and Karachentseva 2004, Cat. ) are FS 20 separated by ~3arcmin (see Fig. A.1), both being within the FS 20 antenna beam. LeG 18 was detected within the Arecibo ALFALFA FS 20 survey as AGC 201970 with V_HI_=636km/s, W50=38km/s, and FS 20 S=0.55Jy/km/s. FS 20 may be probably identified with AGC 205290 FS 20 [10 46 42.4 +12 46 58] with V_HI_=915km/s, W50=50km/s, and FS 20 S=1.46Jy.km/s (Stierwalt et al. 2009AJ....138..338S). FS 20 Both objects are within the so-called "Leo HI ring" FS 20 (Schneider et al. 1983ApJ...273L...1S). CGCG 66-109 This is another dwarf member of the Leo-I group (see Stierwalt et CGCG 66-109 al. 2009AJ....138..338S), for which V_HI_=777km/s, W50=44km/s, and CGCG 66-109 S=1.74Jy.km/s. Its optical velocity, 982+/-78km/s, from the SDSS CGCG 66-109 DR4 corresponds to a blue knot outside the galaxy centre. d1150+5546 The marginal narrow HI line (v=594+/-6km/s) reported by d1150+5546 Karachentsev et al. (2007, Cat. ) lies in a radial d1150+5546 velocity range with frequent RFI. Therefore, we included this d1150+5546 object in Table 3 (upper limits). d1217+4703 = BTS 109. This is a new tiny member of the Canes Venatici I cloud d1217+4703 (see Fig. A.1) with very high HI-mass-to-luminosity ratio of 6.5, d1217+4703 and MT/L_B_=29 in solar units. d1221+2814 = KK 138. Marginal HI detection. The broad HI line width d1221+2814 W50=186km/s yields an extremely high total-mass-to luminosity d1221+2814 ratio of ~250 in solar units. d1233+3806 = BTS 142. This object was detected also in a blind HI survey at d1233+3806 Westerbork (Kovac et al. 2009MNRAS.400..743K); V_HI_=719km/s, d1233+3806 W50=47km/s, and S=0.41Jy.km/s. KKSG 29 This is a probable dwarf companion of NGC 4594 (the "Sombrero" KKSG 29 galaxy); V_LG_=828km/s. Assuming a distance of 9.33Mpc (Ferrarese KKSG 29 et al. 2000ApJS..128..431F) for NGC4594 the projected separation KKSG 29 of KKSG 29 from NGC 4594 is 218kpc. A difference in radial KKSG 29 velocity of 266km/s between both galaxies yields an orbital mass KKSG 29 estimate of 1.2x10^13^M_{sun}_ or M_orb_/L_B_=140 in solar units. KKSG 29 There are four other probable dwarf companions to the Sombrero KKSG 29 galaxy within 200kpc, KKSG 31, KKSG 32, KKSG 33, and KKSG 34; KKSG 29 which are all of type dSphs and not detected in HI. d1243+2956 = BTS 152. This object is HI-rich, a suitable target for a detailed d1243+2956 study in Halpha and HI. d1243+4127 A new dwarf member of the CVn I cloud. It was also detected by d1243+4127 Kovac et al. (2009MNRAS.400..743K) with V_LG_=436km/s. d1312+4147 = KKH 82 = UGCA 337. A new member of the CVn I cloud. Its optical d1312+4147 velocity of 529+/-40km/s (SDSS DR4) agrees well with the HI d1312+4147 velocity. However, the broad HI line width of 234km/s yields an d1312+4147 extremely high M_T_/L_B_=182 in solar units. No suitable object d1312+4147 for confusion could be found within the antenna beam.
