Fig. 31, Lower surface. Fig. 32, Upper surfai-i 



(Natural size. ) 



Eyes largo for a member of this family (li mm.), deep sunk, partially 



covered by tbe thick lids posteriorly and concealed by the dense fur. 



(Not visible in dry skins, but may be found by parting the fur.) 



Ear-conch wanting. Auricular aperture situated above the line of 



fore leg; large, irregular in outline, elongate, its long 



axis directed obliquely downward anteriorly. It has a 



broad internal projection below, 



and a small sei)arate eul de sac at 



the posterior end. The aperture 



is entirely concealed by the fur, 



but its position is indicated by a 



slight depression. 



Fore feet large, but less so than 

 in Scalops. Their breadth almost 

 exactly one half their length (in- 

 cluding the claw). Palms naked, 

 covered with moderate-sized 

 rounded scales. Outer (or upper) 

 edge of the second, third, and fourth toes with three conspicuous flat- 

 fish triangular tubercles; the llrst toe with two, the fifth with none. 

 Backs of the hands covered Avith moderate- 

 sized polygonal scales; those on the toes 

 larger and somewhat symmetrically arranged. 

 First toe shortest; the second, 

 third, and fourth progressively 

 longer; the iifth about as long 

 as the third. Claws depressed, 

 broad, obliquely set; sligntly 

 concave below, except at the 

 tip. Marked on the u])per sur- 

 face with inconspicuous longi- 

 tudinal furrows. A single row 

 of long, rather stiff hairs sur- 

 rounds the palms, and there 

 are two hairs only at the inner 

 edge of the base of each claw. 



The hind feet are one-fourth longer than the fore feet, 

 narrow, scaly. Claws long, compressed. A large de- 

 pressed tubercle at the base of the hallux. Toes naked 

 (except that there are a few hairs at the base of the 

 claws); metatarsus hairy oidy on the outer portion of 

 the ujiper surface. 

 Tail in adults thick, conical, depressed (sometimes terete), with a 

 slender base; covered with snmll scales in regular rows, from the distal 

 margin of each of which three hairs project. These hairs are every- 

 where equally distributed, and are sufficiently numerous to partially 

 conceal the scales.
