. Catalogue of the mammals of western Europe (Europe exclusive of Russia) in the collection of the British Museum. 781 thickened, palmar and plantar tubercles somewhat reduced in size, crowded into a rolati%'ely smsdler area than in P. suhtcrraneus; tail short, scarcely more than one-cjuarter as lung as head and body. Colour.—Upper parts a peculiar drabby grey, varying considerably in exact shade as described under the subspecies, the sides often with a noticeable buffy tinge ; underparts and feet whitish in rather marked contrast with back ; tail whitish, the upper surface usually clouded with brown. Skull.—The skull resembles that of PHjimya Insitcmicus, but its general size is greater, the zygomata are more abruptly spreading, the brain-case is relatively shorter and deeper, and the occiput is more obliquely truncate, so that condyles are' more plainly visible when skull is viewed from above. Depth of rostrum immediately be- hind incisors about equal to width in same I'egion. Interorbital con- striction about as wide as anterior portion of rostrum, its dorsal surface convex laterally ; temporal ridges low and indistinct, scarcely visible except in rather old individuals, sometimes rather closely approach- ing each other, though without coalescing, and seldom if ever extending *back over parietals. Length of brain-case about equal to or slightly less than width across zygomatic roots, the outline when viewed from above sub-quadrate or occasionally almost circular ; postorbital ridges low but attaining a fair degree of development in old age, never, however, strongly angled. Auditory bullas well developed, smooth, their greatest diameter contained about three and a half times in condylobasal length of skull. Palate showing no special peculiarities. Incisive foramina as usual in the genus, their longi- tudinal diameter about equal to one-half distance from gnathion to alveolus of first molar. Teeth.—The teeth of Pitymys ihcricus so exactly resemble those of P.
