BRUES: A NEW PERIPATUS FROM COLOMBIA. 



377 



way from the median line to the legs when seen in dorsal view. Ex- 

 amined in surface view the papillae appear to be practically all of the 

 same type, large and rather transverse in outline. Seen by trans- 

 mitted light, accessory papillae are few in number and always appear 

 on the extreme edges of the folds singly or in pairs between two primary 

 papillae, which are farther apart at the points where accessory ones are 

 interpolated. The primary papillae are short-conical in form, with 

 the terminal cylinder poorly developed, short, nipple-shaped; their 

 bases are usually separated by nearly transverse grooves which give 

 the papillae a somewhat rectangular appearance when viewed from 

 above. The accessory ones tend to project over the groove between 

 the body folds and are thus seen more or less in profile when the 

 integument is viewed from above. In one specimen (Plate 1, fig. 1-2) 

 where the skin is stretched from side to side the primary papillae are 

 more widely separated and the accessory ones appear to be drawn up 

 farther toward the ridges of the body folds. 



Mandibles. The mandibles bear one large accessory tooth and nine 

 denticles. 



Legs. As stated above there are 33-34 pairs of legs in the females 

 and 30 pairs in the single male 

 examined. The legs are provided 

 with three pedal papillae, two on 

 the anterior face and one on the 

 posterior face as in the Caribbean 

 members of the genus. The creep- 

 ing pads of each leg are composefl 

 of four bands. The nephridial 

 tubercles on the fourth and fifth 

 pairs of legs lie between the third 

 and fourth bands of the creeping 

 pad. They are free from the third 

 band although lying partly in an 

 emargination of its proximal mar- 

 gin, and do not disturb the con- 

 tinuity of the fourth band.

 along the coast which has yielded so many species of Peripatus.
