1 Introduction

The current census of galaxies in the Local Volume (= LV) with radial velocities in the Local Group rest frame V0 < 500 km s-1 is very incomplete. Many new objects have been added in the past years even in the Local Group (Armandroff et al. 1998; Armandroff et al. 1999; Karachentsev & Karachentseva 1999; Whiting et al. 1999). The incompleteness is most severe for very low luminosity and low surface brightness dwarf galaxies, the most numerous type of galaxy in the Universe. Over the last two decades the initial list of 179 LV galaxies (with V0 < 500 km s-1) compiled by Kraan-Korteweg & Tammann (1979) has almost doubled.

To increase the completeness of the LV sample, we undertook a systematic search for nearby dwarf galaxies (Karachentseva & Karachentsev 1998), based on POSS-II and ESO/SERC films. In wide vicinity of the 215 known LV galaxies distributed over the whole sky (Karachentsev 1994) we found 260 nearby dwarf galaxy candidates with angular diameters $a \mathrel{\mathchoice {\vcenter{\offinterlineskip\halign{\hfil
$\displaystyle .... The HI survey of these objects carried out by Huchtmeier et al. (2000) showed that the majority of them are members of the Local Supercluster with a median radial velocity $\sim1200$ km s-1. Actually the spatial distribution of these objects is quite similar to the distibution of DDO dwarf galaxies found by van den Bergh (1959) on POSS-I plates. The sky region inspected in our first survey covers only $\sim20$% of the entire- sky area. To reach the whole-sky coverage we extended our survey to the region of the Local Void (Karachentseva et al. 1999) and to the equatorial SERC EJ zone (Karachentsev et al. 2000).

The present paper contains results of supplementary overall searches for new nearby dwarf galaxy candidates in the southern sky $(D < -18\hbox{$^\circ$ })$ based on the ESO/SERC J and R films. Using the same criterion as before we found 81 objects with angular diameters $a \mathrel{\mathchoice {\vcenter{\offinterlineskip\halign{\hfil
$\displaystyle .... This number is comparable to the 95 objects from the first list (Karachentseva & Karachentsev 1998) situated in the same declination range $D < -18\hbox{$^\circ$ }$.
