©rate, broad and rounded, hirsute within the conch, the longest hairs 

 extending 0.8 centimeter beyond the margin. Border of the conch 

 slightly and unevenly notched. Fore feet as in F. zihetliicus. Palm 

 black, except the two large posterior tubercles and the base of the 

 thumb. Hind feet moderate, not equaling twice the length of the fore- 

 feet. Soles naked, smooth, black, and 5-taberculate.* 



The posterior-internal tubercle large and oval in outline. The remain- 

 ing four situated respectively at the angle between the 1st and 2d toes 

 between the 2d and 3d, between the 3d and 4th, and between the 4th 

 and oth; all small and of equal size. Soles narrow. Toes not in- 

 clined laterally at an angle with the sole. Fringe of the toes and sole 

 not extending jirominently below the plane of their lower surface. 



Toes of the fore and hind feet only slightly webbed. Claws horn- 

 colored. Tail round, about 0.6 centimeter at the base and tapering 

 gradually to the tip. Sparsely clothed with short blackish hairs, be- 

 tween which the tail appears covered with rows of scales as in Mus. 



Color of the hair of the body above as in F. zibethicus; rich, rufous at 

 the upper two-fifths and lead-color at the base. In a small area just 

 behind the shoulders the base of the hairs is white. Color of the head 

 the same as of the body, but darker. Hair of the under surface of 

 the body light rufous at the upper third, lead-color at the base. Chin, 

 throat, and inner side of the fore arms and legs white or but faintly 

 tinged with rufous. Fore and hind feet above clothed with short, dull- 

 brown hairs which extend to the tips of the toes. 



The skull, so far as examined, does not differ from that of F. zibethicus 

 except in proportions. 



The species is named in honor of my friend Prof. J. A. Allen, whose 

 well known monographs of North American mammals place him in the 

 front rank of American zoologists.
