In Bouvier's key this species will run down to edwardsU, ]:)ut it is 

 quite different from that species in the form and arrangement of the 

 tegumentary papillae, and also possesses a larger nvimber of legs in the 

 female (33-34 pairs), cdicarclsii having only 30-32, rarely 33 in this sex. 

 Were it not for the presence of incomplete body folds the structure 

 of the integument would place it close to brasiliensis, although the 

 specimens of brasilietisis figured by Bouvier have the primary papillae 

 placed farther apart and the accessory ones ascend to the ridges of the 

 folds. The structure of the fourth and fifth legs is as in brasiliensis 

 also, with the nephridial tubercle entirely free from the third band of 

 the creeping pad. It appears impossible, therefore, to associate the 

 present form closely with an}^ described species, although it undoubt- 

 edly falls near cdwardsii while showing a striking similarity to brasi- 

 liensis. Peripatus brasiliensis was described from Santarem, but ac- 

 cording to Bouvier probably extends to Panama; P. cdwardsii occurs 

 from French Guiana to Colombia. The present species is not closely 

 related to any of the forms recently described by Fuhrmann (Zool. 

 anz., 1913, 42, p. 241-248) from Colombia.

Of this widely distributed species there are nine specimens (Coll. 

 Univ. Mich, and M. C. Z. No. 241-244), from the Cincinnati Coffee 

 Plantation, near Santa Marta, Colombia. 



As can be seen from the accompanying illustrations, there is con- 

 siderable variation in the distribution of the integumentary papillae, 

 particularly in the accessory ones. These latter vary much both in 

 numbers and in distribution on the body folds, but the variation does 

 not exceed that already observed by Bouvier in this species. All 

 have the nephridial tubercles of the fourth and fifth legs free from the 

 third creeping pad and the fourth pad is continuous. The number 

 of legs is indicated in Table 2. 



In the smaller specimens there is a marked difference in the size of 

 the primary papillae which are alternately large with well-developed 

 terminal cylinder and small with reduced cylinder. In these speci- 

 mens the accessory papillae are sparse and restricted almost exclu- 

 sively to the edges of the folds (Plate 2, fig. 7-8). The larger examples 

 (Plate 2, fig. 6, 9) have the primary papillae of more nearly equal size 

 and similar form and the accessory ones ascend more commonly on 

 the sides of the folds although always remaining away from the ridges.
