An annotated list of 31 moss species from the Polica Range in the Beskidy Zachodnie Mountains, Polish Western Carpathians, is provided. Of these, 15 species represent new records for this mountain range, while 16 species have so far been considered to be very rare or rare in this area. Tortula mucronifolia Schwägr. is excluded from the moss flora of the Polica Range and the Beskidy Zachodnie. Bucklandiella affinis is recorded for the second time in the Polish Western Carpathians. This species along with Schistidium trichodon var. trichodon is a new addition to the moss flora of the Beskidy Zachodnie, whilst Ditrichum pusillum, Meesia uliginosa and Schistidium elegantulum represent second records of the species concerned in these mountains. Four species of moss, Schistidium elegantulum, S. trichodon var. trichodon, Bucklandiella affinis, Syntrichia latifolia and Meesia uliginosa are known to occur exclusively in the Polica Range within the Beskid Wysoki. Distribution of all species in the study area is mapped and for some species distribution maps in the Polish Carpathians are provided. The moss flora of the Polica Range consists currently of 278 species and 5 varieties. The diversity of the moss flora in the Beskidy Zachodnie is discussed. The richest muscoflora has the Beskid Wysoki (355 species, 1 subspecies and 11 varieties) which is followed by the Beskid Śląski (304 species and 3 varieties), the Gorce (286 species and 9 varieties) and the Beskid Mały (260 species and 8 varieties). Within the Beskid Wysoki Range the richest moss flora has the Babia Góra massif (280 species, 1 subspecies and 11 varieties) and Polica Range (278 species and 5 varieties).
