1910. Sorex arancus euronotus Trouessart, Faune Mamm. d'Europe, p. 53. 



Type locality. — Montrejeau, Haute-Garonne, France. 



Geographical distribution. — Probably the plains between the 

 Pyrenees and the Garonne. At present known from the type 

 locality only. 



Diagnosis. — Similar to Sorex arancus araneus, but colour in 

 summer (winter pelage not known) more dull, the sides scarcely 

 if at all contrasted with the back, and underparts more heavily 

 washed with wood-brown. Skull with slightly narrower less 

 elevated brain-case, and teeth just perceptibly smaller than in 

 true araneus. 



Measurements. — External measurements of type specimen : 

 head and body, 78; tail, 44; hind foot (dry), 12 '6. Average 

 and extremes of nine specimens from the type locality : head and 

 body, 71-4 (67-78); tail, 42 (37-44); hind foot (dry), 12-5 

 (12 • 2-13 "0). For cranial measurements see Table, p. 51. 



Specimens examined. — Nine, all from the type locality (U.S.N.M.). 



Sorex araneus bergensis Miller. 



1909. Sorex arancus bergensis Miller, Ann. and Mag. Nat. Hist., 8th ser., 



Ill, p. 416, May, 1909. Type in U.S. National Museum. 



1910. Sorex araneus bergensis Trouessart, Faune Mamm. d'Europe, p. 52. 



Type locality. — Graven, Hardanger, Norway. 



Geographical distribution. — Western Norway, from region of 

 Bergen, north at least into Nordland. 



Diagnosis. — Larger than Sorex araneus araneus (hind foot, 

 13-6 to 14-4 mm. ; condylobasal length of skull, 19 to 20 mm.), 

 and colour in summer pelage darker, the dark brown or blackish 

 dorsal area sharply defined from the yellowish brown of sides. 



Colour. — Dorsal area well defined, ranging from a blackish 

 seal-brown to bister, usually darker on rump and lumbar region 

 than on head, and almost invariably with sharp lateral line 

 of demarcation. Sides yellowish isabella-colour. Underparts 

 greyish, washed with light wood-brown. The contrast between 

 colour of sides and underparts, though less marked than that 

 between sides and back, is usually evident. Feet scantily clothed 

 with inconspicuous Isabella-coloured or dusky hairs. Tail obscurely 

 bicolor, brownish above, dull yellowish below. 



Skull and teeth. — The skull and teeth do not differ appreciably 

 from those of Sorex arancus araneus, except in their larger size, 

 as shown by the detailed measurements. The j^igmentation of
