Shortly afterwards SUCIU (1969) found the same form in the Retezat Mountains (Gura Zlata), described it as a subspecies of C. capriciosus and called it C. capriciosus carpaticus. Accepting the priority of VYSOTSKAYA's description, this subspecies was synonymized (SUCIU, 1969) to C. capriciosus bychowskyi. General distribution: Roumania and USSR. 10. Peromyscopsylla silvatica (Meinert, 1869) Material: Id 1 , 4 g, Gura Zlata, 20 October, 1967, from Microtus arvalis; 1 g, the Gemeni Peak, 25 October, 1967, from Sorex araneus tetragonurus.
