Feet relatively larger than in Sorex araneus, but not i^eculiar in form. Colour.—-Entire upper parts a deep slaty grey produced by the combination of blackish-slate under colour and short seal- brown tips, lightened to a varying degree by silvery sub-terminal annulations. Underparts slightly washed with sepia, but the difference in colour of the two sux-faces not conspicuous, and sides entirely without line of demarcation. Feet scantily clothed with silvery hairs. Tail sharjjly bicolor, nearly black above and at tip, buffy whitish below, the light area always less extensive than the dark, and sometimes reduced on distal half of tail to a narrow median line. Shull.—The skull, though of the same general dimensions as that of Sorex araneus, is recognizable by its less elevated brain-case* the outline of which when viewed from above is more nearly circular, owing to the very slight flattening of antero-external portion of border. Inter- orbital region less tapering than in the related species, a character due to the slightly though appreciably greater lachrymal breadth. The diameter of the tympanic ring is usually though not constantly less than in Sorex araneus. Anteorbital foramen slightly larger than in S. araneus.

Teeth.—Relatively to size of skull the teeth are noticeably smaller than in Sorex araneus ; this is particularly evident in the anterior upper incisor when viewed from the side, and the upper unicuspids when viewed from below. Anterior upper incisor with basal lobe even smaller than in *S^. minutus, its height slightly less than that of first unicuspid and much less than t
