are heavily and almost symmetrically marked with white, the remainder 

 of the pelage being drabbish brown, paler on the under parts. The 

 face has the usual white frontal marking and the blackish streak crossing 

 the eye. The chin and throat have numerous hairs broadly tipped with 

 chestnut. The skull differs in many respects from that of tridactyla 

 from Guiana and there can be no question of its distinctness. Whether 

 it should be given a new name or not can be determined only by examina- 

 tion of various old types most of which are in European museums and 

 lacking in exact data. Gray's name blainvillei has been used for speci- 

 mens from the Ucayali River 1 probably representing the species to which 

 our specimen belongs, but as the original basis of the name was a skull 

 without definite locality, there is no certainty in its use at present. 



Tayassu pecari Fischer. WHITE-LIPPED PECCARY. 



Two specimens, Tambo Almirante. 



Peccaries range through the heavy forest of the east slope of the 

 eastern cordillera up to an altitude of 6,000 ft. or more. The natives 

 carrying freight between Chachapoyas and Moyobamba generally have 

 with them old fashioned guns mainly in the hope that they may en- 

 counter a herd of these animals the flesh of which they highly prize. 

 Perhaps for this reason, we saw but few tracks near the main trail. 



Returning to camp one morning during a heavy downpour of rain, 

 I heard a faint sound from a wooded quebrada some distance below me 

 and was just concluding it to be the note of some unknown bird less 

 distant, when a breath of wind brought it more clearly to my ears and 

 I recognized a squealing, piglike quality in it. Going a little nearer, 

 I was no longer in doubt and following the sound, soon worked my 

 way through heavy timber and thick underbrush to the edge of a sharp 

 cut bank which dropped some thirty feet down to the bottom of the 

 practically waterless quebrada. The growling, squealing din was then 

 just below me and added to it was the lively click of snapping tusks 

 apparently only a family quarrel, but being waged with considerable 

 vigor. For a few seconds I could see nothing but an occasional waving 

 bush. Then I gradually made out the dark bodies of several peccaries 

 moving about on the other side and near the bottom of the quebrada. 

 They were difficult to see since there was a heavy growth of large brake 

 ferns under which they were passing and in the deep shade their blackish 

 bodies gave little contrast to the ground. Picking out two of the 

 largest ones, I dropped them in their tracks and was just aiming at a
