 between the pads are occupied by small isolated nodules of horny 

 integument. In Perodicticus and Nycticebus, on the other hand, the 

 palms of both the feet and the hands are flesh-coloured, and the 

 interspaces between the pads are traversed by irregular creases and not 

 separated into distinct and isolated nodules of horny matter. 



On the inner side of tiie arm close to the wrist is an oval patch

 these peculiar spines could be observed. The Natural-History
