MONOGEAPH OP THE GENUS PERIPATUS. 453 



Of these five varieties I have not seen the first two. I have, 

 however, had full opportunity of examining preserved speci- 

 mens of the last three and will now shortly describe my obser- 

 vations on them. 



Peripatus with twenty pairs of claw-bearing legs. — 

 One specimen only — a female — is known to me. Locality, 

 Table Mountain. Length of spirit specimen 23 mm. 



The specimen very closely resembles P. Balfouri, and would 

 be mistaken for the latter were not its legs counted. The skin 

 presents an identical appearance. The last pair of legs are 

 very small and rudimentary, and the generative opening, which 

 is subterminal just in front of the anus, is between them. 



The first nineteen pairs of legs are all normal and resemble 

 exactly, so far as I can judge, those of P. Balfouri. In the 

 legs of the twentieth pair, while the foot is normal the leg is 

 much reduced in size. It is entirely without the spinous pads, 

 and possesses only three rows of papillae of which the row next 

 the foot is slightly tinged with green, the other two being 

 white. 



The only other difference which I was able to detect between 

 this specimen and P. Balfouri consisted in the very small amount 

 of green on the ventral surface, which is almost white. 



On the whole I am not inclined to establish at present a 

 distinct species for the reception of this specimen, but would 

 prefer to regard it provisionally as a variety of P. Balfouri. 



Peripatus Moseleyi. 



South African Peripatus, with twenty-one and twenty-two 

 pairs of legs. 



All the specimens under this head presented the same 

 general appearance (fig. 24). Were it not for the number of 

 legs they would be taken for specimens of Capensis. The 

 ventral surface is light brown and the dorsal an olive green, 

 with scattered brown patches. Green is entirely absent from 

 the ventral surface, excepting on the foot and distal pad, and 

 sometimes a very little on the middle pad. On the dorsal sur- 

 face there is a band on each side at the base of the legs, in
