Tyjw localitij. — Chesieres, Alpes A^audoises, Switzerland. 

 Altitude, 1,230 m. 



Geographical (listrihitlon. — Pyrenees and Aljjs ; Hungary. 

 Details of distribution not j^et known. 



Diagnosis. — Slightly smaller than Neomys fodiens : tail with 

 keel absent, oi* represented by a slight lengthening of hairs on 

 under side of terminal third only ; fringes on sides of feet not 

 conspicuously developed; hind foot usually less than 17 mm.; 

 tail usually less than 55 mm. ; lachrymal foramen opening over 

 point of contact between m^ and vf ; anterior upper incisor 

 slendei". 



External characters. — Similar to Neomys fodiens, except that 

 the feet are less fringed and the tail lacks the definite keel on 

 under side. When unworn the hairs on ventral surface of tail 

 are slightly longer than those on upper side, and on terminal 

 third this elongation is occasionally sufficient to produce a 

 rudimentary keel ; but there is never any trace of a well- 

 defined ridge extending to base of tail. Caudal annulations 

 slightly less distinct than in Neomi/s fodiens. Mamma^ : a 1-1, 

 i 4_4 = 10. 



Colour. — The colour is similar to that of typical specimens of 

 Neomys fodiens fodiens. Among the skins examined none shows 

 any noticeable wash of lirown or suffusion of buff on underparts. 



Skull and Teeth. — The skull closely resembles that of Neomys 

 fodiens, but may be distinguished by its smaller general size and 

 relatively lower, more slender rostrum ; lachrymal foramen over 

 point of contact of m^ and nr. Teeth smaller throughout, a 

 difference especially noticeable in the anterior upper incisor. 

 Upper unicuspids with crowns longer and narrower than in 

 Neomys fodiens, the long posterior portion especially noticeable 

 in lateral view by comparison with height of cusp ; cingula 

 not so well developed as in the related species, and seldom, if 

 ever, forming a postero-external cusp. 



Measurements. — External measurements of type: head and 

 body, 7G ; tail, 59 ; hind foot, 16 ; hind foot, including claws, 

 17. Average and extremes of ten specimens from the tyjje 

 locality: head and body, 77-4 (71-87); tail, 53-7 (50-59); 

 hind foot, 15 "8 (15-16 '2). Average and extremes of six 

 .specimens from Untervatz, Grisons, Switzerland : head and body, 

 79-3 (75-82); tail, 46-8(45-51); hind foot, 14-16 (14-15-4). 

 Two adult males from Locarno, Ticino, Switzerland : head and 

 body, 86 ; tail, 50 and 53 ; hind foot, 16 and 17. Average and 

 extremes of three adult females from 1' Hospitalet, Ariege,
