 Foot as long as or longer than the tibia ; toes entirely 

 or almost entirely webbed, with small subarticular 

 tubercles ; inner metatarsal tubercle varying in shape 

 and size according to the varieties, oval and feebly pro-

 tubercle usually present at the base of the fourth toe. 



Skin smooth or verrucose, usually with small granu-

 glandular dorso-lateral fold ; these folds parallel or 

 slightly diverging towards the sacrum, the distance 

 between them on the scapular region one-sixth to one-

 females, and in a large female from Pisa I even find
