8i: 



the plantar pads are smaller, more subdivided, tlieir pollical and 

 hallucal elements are connected by a narrow strip with the main 

 pad, and the carpal pads are much rediiced and separated by a

 digital pads are narrowly ovate, the plantar pads are broken up 

 into four areas connected by nai^row naked strips, and the cnrpals 

 are quite small.
