The following list gives the numbers of pairs of legs in 

 the better known species of Peripatus, from both hemispheres, 

 as recorded by Sedgwick : 



Peripatus brevis Blainv. S. Africa. 14 



novae zealandiae Hutton. New Zealand. 15 



leuckarti Saenger. Queensland. 15 



capensis Grube. S. Africa. 17
