notch is continued backward on upper surface as a narrow 

 groove still further dividing the two lobes ; on under side 

 it is continuous with a similar though much longer groove 

 extending to middle of upper lip. Each lobe is further 

 marked by a narrow groove extending backward and slightly 

 inward from near outer edge of nostril. Surface of lobes 

 very finely rugose and pitted, that of rest of muzzle coarsely 

 rugose and without pits. Behind lobes the muzzle is naked 

 along median region, thinly haired at sides and beneath. 

 Eye minute, essentially as in Talpa, though probably never 

 covered by the integument. No external ear, the meatus about 

 4 mm. in diameter. Eront feet rather large and broad, readily 



turned outward but not perma- 

 nently in this position, the five 

 short fingers joined by a narrow 

 web, and armed with strong, 

 slightly curved claws 4 to 5 mm. 

 in length ; fourth digit longest, 

 fifth and third sub-equal and 

 slightly shorter, second and first 

 still shorter. Palms naked, their 

 surface finely tuberculo - rugose, 

 without trace of larger tubercles, 

 though the surface is marked 

 by three deep wrinkles ; balls of 

 digits projecting conspicuously 

 beneath bases of claws. Dorsal 

 surface of front foot covered 

 with minute hairs, these lengthen- 

 ing along edges to form distinct 

 fringes. Hind foot much larger 

 than front foot, the toes webbed 

 to base of claws, the claws 

 similar to those on front foot 

 but larger ■ fourth digit longest, 

 third, fifth, second and first suc- 

 cessively shorter, the first extending nearly to end of first 

 phalanx of second ; surface of sole like that of palm, the 

 three longitudinal wrinkles at bases of digits well developed, 

 the large inner tubercle present in the moles very slightly 

 developed, its extremity not projecting like a supplemental 

 digit. Upper surface of hind foot naked, somewhat more 

 coarsely tuberculate than sole. A fringe of stiffened hairs 

 along outer edge of outer toe and continuing along foot 

 nearly to heel. Tail longer than head and body, terete except 

 at tip, where it is flattened laterally. Scales arranged in some- 

 what irregular rings, of which there are about nine to the 

 centimeter at middle of tail. Hairs of tail short, not conceal- 

 ing scales except on flattened terminal portion, where they form
