The important geographical variation of the araneus group species over their distribution area (Loch 1977; Hausser 1984) recommends the use of our function for the Iberian specimens, even though it includes one more variable than the formula of Hausser & Jammot (1974). It has been demonstrated that jaw measurements are more appropriate than skull measurements to analyse morphometrical relationships between shrews ( Hausser & Jammot 1974). However, a discriminant analysis on skull parameters between S. araneus and S. coronatus was performed, in order to provide supplementary infor- mation about the morphometrical differences between these two species in Spain. In spite of the restriction that the function can have for owl-pellet material, it can be easier to apply to captured animals, especially when mandibular variables are dif-.
