MONOGRAPH OF THE GENUS PERIPATUS. 487 



seminis present. Unpaired portion of vas deferens long and complicated. 



Ova large and heavily charged with yolk. 

 P. Novse-zealandise (Hutton). — Australasian Peripatus, without an accessory 



tooth on the outer blade of the jaw, and without a white papilla on the base 



of the last leg of the mule. New Zealand. 

 P. Leuckarti (Saenger). — Australasian Peripatus, with an accessory tooth on 



the outer blade of the jaw, and a white papilla on the base of the last leg 



of the male. Queensland. 



Neotropical Species. 



With four spinous pads on the legs, and the generative aperture between the legs 

 of the penultimate pair. Dorsal white line absent. Primary papillce 

 divided into two portions. Inner blade of jaw with gap between the first 

 minor tooth and the rest. Oviducts provided with receptacula ovorum and 

 seminis. Unpaired part of vas deferens very long and complicated. Ova 

 minute, without food -yolk. {Legs not constant in number in the same species.) 



P. Edwardsii. 1 — Neotropical Peripatus from Caracas, with a variable 

 number of ambulatory legs {twenty -nine to thirty four). Males with twenty- 

 nine or thirty legs, and tubercles on a varying number of the posterior legs. 

 The basal part of the primary papilla is cylindrical. 



P. Trinidadensis (n. sp.). — Neotropical Peripatus from Trinidad, with 

 twenty-eight to thirty -one pairs of ambulatory legs, and a large number of 

 teeth on the inner blade of the jaw. The basal portion of the primary 

 papilla is conical. 



P. torquatus (Kennel). — Neotropical Peripatus from Trinidad, with forty -one 

 to forty-two pairs of ambulatory legs. With a transversely placed bright 

 yellow band on the dorsal surface behind the head. 



Doubtful Species. 



The above are probably distinct species. Of the remainder we do not know 

 enough to say whether they are distinct species or not. The following is 

 a list of these doubtful species, with localities and principal characters. 



P. juliformis (Guilding). — Neotropical Peripatus from St. Vincent, with 

 thirty-three pairs of ambulatory legs. 



P. Chiliensis (Gay). — Neotropical Peripatus from Chili, with nineteen pairs 

 of ambulatory legs. 



P. demerararms (Sclater). 1 — Neotropical Peripatus from Maccasseema, 



1 This name was first applied by Blanchard (No. 8) to a species from 

 Cayenne (vide above, p. 478). The description, however, is very imperfect, 

 and it is by no means clear that the Cayenne species is identical with the 

 species here named Edwardsii.
