170 THE GENUS PERIPATtJS. 



which the brown papillae are so numerous as to cause the 

 appearance of a brown band. Elsewhere on the dorsal surface 

 the brown papillge are very sparsely scattered. 



They are all reported from a part of South Africa far removed 

 from Table Mountain, the home of Balfouri and Capensis, 

 viz. near Williamstown (with the possible exception of the 

 one figured, the locality of which I do not know). Unfortu- 

 nately I have only been able to see preserved specimens, which, 

 on account of the great contraction they had undergone in 

 dying, were not very favorable for observation.^ 



Specimens of Peripatus Moseleyi with twenty-one pairs of 

 legs. — Skin as in Capensis. Foot and legs as in Capensis. 

 At the bases of some of the legs (no constancy in the different 

 specimens), immediately internal to the opening of the segmental 

 organ, a small white patch of a tumid appearance is present. 

 It occupies the same position as the large tumid papillae on the 

 ventral side of the leg of Capensis (see PI. XVI, fig. 2), 

 and has been noticed by Wood Mason (No. 23). The generative 

 opening is subterminal, and on each side of it there is an in- 

 conspicuous anal papilla. The dorsal side of the foot is marked 

 with streaks of green pigment, arranged parallel to its long 

 axis. The streaks are much less distinct on the anterior than 

 on the posterior feet. 



Two of the specimens were smaller than the third, from 

 which they differed by possessing a distinct white papilla on 

 the last (twenty-first) leg, exactly resembling in appearance 

 and position the papilla on the last leg of Capensis. I 

 opened one of these smaller specimens, and found it to be a 

 male ; while the larger specimen turned out to be a female. 



The female was about 26 mm. in length, the male about 

 20 mm. 



The specimens of P. Moseleyi with twenty-two pairs of legs 

 were both females. They resemble the specimens with twenty- 

 one legs, so far as I could see from a study of the contracted 



' Drowning (twenty-four hours or more) and then spirit is the best method 

 of killing Peripatus for museum purposes and observation of external 

 characters.
