No. 9. — A New Peripatus from Colombia} 

 By Charles T. Brues. 



The Bryant Walker E>q)edition, of the University of Michigan, 

 which visited the Sierra Nevada de Santa Marta in northeastern Co- 

 lombia during the summer of 1913, obtained an interesting series of 

 Onychophora. Through the kindness of Dr. A. G. Ruthven, the 

 leader of the Expedition, I have had the opportunity of examining 

 these specimens which were collected by himself and Prof. A. S. Pearse. 

 Professor Pearse made some valuable field notes at the time the ani- 

 mals v.ere obtained, and these are of such interest, that they are 

 included separately at the end of the taxonomic account. 



Three species are represented in the collection, P. edwardsii and 

 P. imthurmi in addition to the one described as new. All belong 

 to Bouvier's (Monographie des onychophores, 1907, p. 158) group of 

 "Peripates caraibes" which has lately been given the subgeneric 

 name of Epiperipatus by Clark (Proc. Biol. soc. Washington, 1913, 

 26, p. 17). It may be mentioned, however, that Bouvier's division 

 of the neotropical forms into Andicolous and Caribbean species does 

 not hold for the Colombian species as has recently been shown by 

 Fuhrmann (Zool. anz., 1913, 42, p. 242). 



Peripatus (Epiperipatus) vespuccii, sp. nov. 

 Plate 1, fig. 1-4; Plate 2, fig. 7. 



A small, moderately slender species with 33 or 34 pairs of legs in the 

 female and 30 pairs in the male. Integument similar to that of P. 

 hrasiliensis, but there are two incomplete folds on each body segment. 



Form and dimensions. Body rather slender, considerably narrowed 

 at each end, so that it tapers very decidedly from a broadened middle 

 portion toward the head and posterior end. In the three specimens 

 before me, the body measurements are as follows : —
