The earthworms of the mountainous mass of the N.W. region of Pella province and the Eastern region of Kozani and Florina provinces have been studied. The presence of Allolobophora minuscola is interesting because this species is rare in North Greek oligochaetofauna. In addition the subspecies Helodrilus antipai tuberculatus is widespread although the typical form is rare in this region. Soil pH ranged from 4.9 to 6.9 and the number of individuals decreases significantly with increasing pH. Increased sand content of the soil was significantly related to increased number of species. Other relationships, including number of individuals and species with soil organic matter, were not significant
