mala, hence the fact of having collected only three apecimena from the two host apeciea in thia territory was rather surprising . Ctenophthalmus obtusus Jordan and Rothschild Host: Clethrionomys glareolus, 2 November: 1 S and 1 9 This species was described by JORDAN and ROTHSCHILD (1912) on the basis of specimens found on M. agrestis and C. glareolus near Biharfüred. In Hungary it was expected to occur in the Central Range of Mountains; HAITLINGER (1973) was the first to discover two male exemplars on Pitymys subterraneus at the Kékestető, the present occurrence is regarded as the second collection in Hungary, and the first record of a female specimen. Palaeopsylla soricis rosickyi Smit Host: Sorex araneus, 1 November: 1 o; 2 o, 3 ?; 2 $; 2 November: 1 $; 2 ó\ 5 9; 1 o Host: Apodemus agrárius, 2 November: 1 9 Host: Clethrionomys glareolus, 2 November: 1 o The most frequent specific flea of our shrews. Where shrews are present in great number this flea species can be found also on various mouse species. Palaeopsylla similis similis Dampf Host: Sorex araneus, 2 November: 1 Ç, 1 Í The specific flea of Talpa europaea, rarely appearing on other host species, in cases when the mole-mounds of different host species are communicating. In Hungary I discovered only two female specimens on S. araneus at a single occasion, together with Doratopsylla d.dasvcnema. in the Börzsöny Mountains (Deszkáspuszta) where many mole-mounds were present as in the territory of the project.
