194 THE GENUS PERIPATUS. 



One of these specimens had thirty-one pairs of legs and the 

 other thirty, from which it appears that Kennel, like so many 

 other zoologists who have examined Peri pat us, has not been 

 very careful in counting the legs. The dorsal surface was of a 

 chocolate colour, the ventral surface being a light brown. 

 The papillae and ridges of the skin presented the features 

 characteristic of the Neotropical species. The bases of the 

 primary papillae are conical as in Demeraranus. The jaws 

 also presented no points of diflference from those of the species 

 from Caracas, excepting that possibly the number of minor 

 teeth was rather larger : in one I found as many as eleven 



I think there can be no doubt that this is a distinct species, 

 and I propose to call it and define it as follows : 



Peripatus Trinidadensis [Edwardsii, Kennel). 

 Peripatus from Trinidad, with twenty-eight to thirty-one 

 pairs of ambulatory legs, and a large number of minor teeth on 

 the inner blade of the jaw. The basal portions of the primary 

 papilla are conical. 



Peripatus torquatus (Kennel). 



Peripatus from Trinidad of large size, with forty -one to 

 forty-two pairs of ambulatory legs. The head is marked off 

 from the body by a bright yellow band on the dorsal surface. 



The larger species is named P. torquatus, and Kennel gives 

 the following description of it. " The females reach the length 

 of 15 cm., with a diameter of 8 mm., while the males have a 

 length of about 10 cm. The colour of the dorsal surface is 

 red brown, the middle line of the back being somewhat darker, 

 and paling off towards the sides. The head with the tentacles 

 is black and is marked off from the body on the dorsal side 

 by a bright yellow band, which often shows a small interrup- 

 tion in the middle line. The ventral surface has a dark flesh 

 colour. There are forty-one or forty-two pairs of legs. 



This completes the list of the Neotropical Peripatus of 

 which we have anything like detailed knowledge. The remain-
