The present research follows two other earlier papers on the Bulgarian cave fauna (1962 and 1967). The three papers regroup the data on 431 Bulgarian karst caves, more or less studied from a biospeleological point of view. In this paper one will find a list of 147 new caves and pits with 293 animal species, of which 154 have not been mentioned in the earlier papers. A reference list containing 55 titles has been attached.
