A total of 598 Austrian and 1117 Polish skulls of brown haros Lepus europaeus Pallas, 1778 was examined for dental anomalies, occurrence of Wormian bones and formation of a fenestra in the fossa mandibulars assis temporalis. In addition, the degree of ossification of skull sutures and frequencies oi traceable interparietal sutures were analysed in Austrian hares. Frequencies of missing M3 were 1.95% for Austrian and 2.1% for Polish hares from 1986 - 1990. No significant differences as to age or sex were found for incidences of missing M'1; the left side of the tooth row was significantly more often affected by missing M'\ which indicates directional asym­metry. Rotation of the I2 (mainly of low magnitude) was noticed in 27.9% of subadult and adult Austrian hares. Occurrences of all other dental anomalies such as abnormal shape of M', missing I2, missing M3, supernumerary I2, additional upper molar and various cases of malformation or irregular position of teeth were very low, respectively. Ossification of skull sutures was presently rcduced as compared to the material in­vestigated by Cabofi-Raczyftska (1964) and regional differences in the degree of suturai obliteration were found. Temporal fenestration was encountered in 24.6% of subadult and adulL Austrian hares and in 11.6% in Polish hares sampled during 1986 - 1990 (p < 0.001). Frequency of temporal fenestration increased with age: 2.9% in fetuses/ neonates, 16.5% in subadult and 28.1% in adult hares from Austria (p < 0.01, d.f. = 2); 8.7% in subadult and 23.8% in adult Polish specimens. Average frequency of Wormian bones in Austrian hares was 4.8% and 4.4% in the Polish material. Within subadults 3.7% of males and 16.3% of females (p < 0.01) exhibited a traceable outline of the os interparietale.
