INSECTIVORA 



teeth (incisors both above and below, and first and second upper 

 unicuspids) enlarged. 



Colour. — Summer pelage about like that of S. araneus araneus, 

 but upper parts perhaps not so dark. Sides apparently averaging 

 lighter than in true araneus, and underparts in some specimens 

 a very pale, almost whitish, buffy grey, decidedly lighter than in 

 any skins of the other races yet examined. 



Skull. — In size and general form the skull does not differ 

 appreciably from that, of true Sorex araneus, but on comparison 

 of specimens the rostral portion in front of large premolar is 

 seen to be relatively shorter, broader and deeper. The greater 

 breadth is especially noticeable from below, the space between 

 the anterior unicuspids about equalling diameter of these teeth, 

 while in all the other races (except S. a. granarius) it is evidently 

 less. 



Teeth. — While in general the teeth resemble those of Sorex 

 araneus araneus, the large incisors both above and below are 

 appreciably more robust, and the first and second upper uni- 

 cuspids are wider. The difference is particularly noticeable in 

 the lower incisor, the shaft of which is thickened and the lobes 

 on cutting edge distinctly enlarged. 



Measurements. — External measurements of type (adult female) : 

 head and body, 63; tail, 48-2; hind foot, 13. For cranial 

 measurements see Table, p. 51. 



Specimens examined.— Five, all from the island of Jersey. 



Remarks. — The Jersey shrew is easily distinguishable from 

 the other races by its enlarged anterior teeth. It is probable 

 that a sufficient series of skins will show that there is an average 

 difference in colour as well.

Type locality. — La Granja, Segovia, Spain. 



Geographical distribution. — At present known from the type 

 locality only, and probably confined to the mountains of central 

 Spain. 



Diagnosis. — Smallest known European race of Sorex araneus, 

 the condylobasal length of skull only about 17 • 5 mm., upper 

 tooth-row about 7 • 5 mm. ; palate wide anteriorly as in S. araneus 

 fretalis, but anterior teeth not enlarged. 



External characters and colour. — Externally the animal shows 

 no special peculiarities, though the ear and the plantar tubercles
