. Bonner zoologische Beiträge : Herausgeber: Zoologisches Forschungsinstitut und Museum Alexander Koenig, Bonn. Biology; Zoology. Indigenous hares of Italy 67. contour of the skull from an lateral view in L. europaeus is straighter than in L. corsi- canus which has a more rounded shape. This is mainly the effect of the nasals that are generally flat and long in L. europaeus and somewhat curved and shorter in L. corsicanus, as well as the brain case which in L. corsicanus is more rounded than in L. europaeus. However, most of the morphological difference between L. corsicanus and L. europaeus is the result of the influence of a number of skull structures related to 15 different characters, which are compared in the two species below. The charac- ter states presented by each specimen are shown in Tab. 5. A) Position of the lateral foramen palatinum (Fig. 2, a, 1). — In L. corsicanus specimens these foramina are normally visible on the ventral plate of the palatine process of the maxilla, near the P2/ (state 1). Some specimens of L. corsicanus have a second pair of foramina occu- pying the position defined below as typical for L. europaeus, or in an intermediate site (state 2) between the position typical for L. europaeus and the position defined as state 1. Most of the specimens of L. europaeus have these small foramina on the anterior edge of the palatine process of the maxilla, positioned laterally (state 3). This site is internal to the incisive fora- mina and is not visible from the perpendicular to the skull in ventral position. L. europaeus specimens with a second pair of foramina near P2/ or in an intermediate position are not common. B) Position of the posterior foramen palatinum (Fig. 2, a, 2). — Most L. corsicanus speci- mens have these foramina totally enclosed in the lamina horizontalis of the palatine bone (state 1) while in L. europaeus these foramina are positioned exactly on the suture separating the lamina horizontalis from the palatine process o
