NOTES ON THE ANATOMY OF PERIPATUS. 495 



Notes on the Anatomy of Peripatus capensis 

 and Peripatns Novae-Zealandise. 



By

There are a few anatomical details in which these two 

 species of Peripatus differ both from one another and from P. 

 Edwardsii, the anatomy of which has been described by 

 Gaffron (2). 



Crural Glands. 



I have examined several legs of P. capensis, both of males 

 and females, and have found a crural gland in every one, 

 except the first pair of legs. 



Except those of the fourth and fifth, and in the male of the 

 last pair of legs, the glands all resemble one another in their 

 structure, in the position of the gland and duct, and in the 

 point at which the latter opens, viz. on the ventral surface of 

 the leg external to the opening of the duct of the segmental 

 organ. 



The glands of the fourth and fifth pairs of legs are very 

 much smaller than the others, and open internally to the seg- 

 mental organs, in the angle formed by the junction of the 

 leg with the body. The gland of the last leg of the male is 

 very long, and extends forwards through many segments of 

 the body, being apparently modified in connection with the 

 male generative organs. 



These organs have all been previously described by Professor 

 Balfour (1).
