INSECTIVORA Outline when viewed from the side long wedge-shaped, rounded off posteriorlj. Surface of skull smooth, except for a slight sagittal crest, present in old individuals along course of parietal suture, and a crest-like elevation extending forward and outward from antero-external angle of interparietal along edge of slightly inflated mastoid region, and terminating anteriorly in a slightly pointed projection.

. Catalogue of the mammals of Western Europe (Europe exclusive of Russia) in the collection of the British museum. Mammals. INSECTIVORA Outline when viewed from the side long wedge-shaped, rounded off posteriorlj. Surface of skull smooth, except for a slight sagittal crest, present in old individuals along course of parietal suture, and a crest-like elevation extending forward and outward from antero-external angle of interparietal along edge of slightly inflated mastoid region, and terminating anteriorly in a slightly pointed projection. Brain-case with posterior margin nearly semi- circular to projecting points already mentioned, then abruptly conical to back of interorbital region, its outline when viewed from behind fusiform, a little less than half as deep as wide; condyles slightly projecting, but not noticeably breaking general posterior outline. Interparietal large, strap-shaped, slightly convex in front, similarly concave behind, the lateral extremities squarely truncate, its antero-pos- terior diameter about one-third transverse diameter. Its anterior and lateral sutures remain visible, but the lambdoid suture is nearly obliterated earh^ in life, though its position is usually marked by a slight ridge representing the lambdoid crest. Base of brain- case smooth, without cousf)icuous ridges, furrows or open sj^aces, the bones for the most part some- what inflated ; two ill-defined pits in surface of basioccipital in front of foramen magnum ; a shallow, broadly triangular median furrow between the low, flattened bullae, the sub-circular, slightly triangu- lar outline of which is sometimes distinctly indicated, but more often very obscure ; auditory meatus small, nearly circular. Inner pterygoid plate small but well developed, the hamulars short, turned slightly outward; mesopterygoid space much narrower posteriorly than anteriorly, its greatest breadth less than half length, its length much more than width of palate between posterior molars, its anterior bord
