40 PERIPATUS. 



pouding very well witli Hutton's description , is olive-green, 

 marbled with brown , with a light lateral band above the legs 

 and a row of x-shaped white spots along the middle of 

 the ventral side. A dark line, running along the middle of 

 the back , is produced by a groove , like in the Sumatra- 

 specimen. The legs are longer , situated at a much greater 

 distance from each other than in our specimen; they are 

 furnished at their ventral side only with three pads, two 

 broad distal and a proximal one, resembling those of P. 

 capensis. The 4th and 5th pair of legs are characterized 

 by possessing a white papilla on the proximal pad. The 

 anus is exactly terminal and the generative aperture situated 

 between the last pair of legs, like in P. capensis; if this 

 last pair is provided with claws or not, I could not make 

 out , because they seemed not quite intact. 



Comparing our Sumatra-specimen with P. Edwardsii, we 

 find more resemblance with this species than with any 

 one of the Eastern hemisphere, except in the number of 

 legs , which usually seems to amount to thirty pairs. ^) In 

 P. Edwardsii not only the structure of the skin Cwith its 

 characteristic papillae) and the shape of the legs seem to 

 be similar to that of the Sumatra-specimen , but moreover 

 the generative orifice is situated between the penultimate 

 pair of legs , on the third ring from the end of the body. 

 Having only a single specimen at my disposal, I could 

 not examine the structure of the internal organs ; it should 

 not have been without interest , because the examination of 

 the species , above referred to , has learned us , that in P. 

 Edwardsii the female reproductive organ is provided with 

 a receptaculum seminis , while P. capensis and P. Novae- 

 Zealandiae seem to want it. 



1) Peters (Sitzungsber. Gesellsch. Naturf. Frennde zu Berlin, 1880, p. 28) 

 mentions specimens from Portorico with only 27 pairs of legs; Grube observed 

 a specimen with 29 pairs.
