ON A SPECIMEN OE PERIPATUS, GUILD. 

 FROM SUMATRA. 



Dr. R. HORST. 



(Plate 2 , fig. 1—5). 



The species of the interesting genus Péripatus , hitherto 

 mentioned, are only found in three parts of the globe, 

 far distant from each other : South America (including the 

 West- Indies) , the Cape of Good Hope and New-Zealand. 

 Therefore it seems not without interest to me, to give a 

 short description of a specimen, found by my colleague 

 Mr. Ritsema in a bottle with Insects from East-Sumatra, 

 presented to our Museum by Mr. W. E. J. Hekmeyer. 



The length of the whole animal measures only 25 m.m., 

 its greatest breadth S'/g m.m. The dorsal side of the body 

 is slightly arched , its ventral surface nearly flat ; there is 

 a narrow shallow groove running along the middle of the 

 back. The skin presents narrow transverse ridges , passing 

 between the legs from the dorsal to the ventral side and 

 surrounding the whole body ; the legs are also faintly 

 ringed. The ridges are beset by a number of warts , which 

 are very developed on the legs. Each wart appears to con- 

 sist of a truncated cone , bearing on its top a small cylinder , 

 provided with a spine , while the surface of the wart is 

 covered by numerous minute tubercles , which are also 

 scattered over the whole skin between the warts, giving 

 it a net-like appearance. 



The antennae have a length of 4 m.m. and taper slightly 

 till near their top , where they present a club-shaped enlar-
