 or clay color, with a less distinct vertebral black stripe. 



Cranial <m<l dental characters. — The lateral dentition seems to be 

 simpler and lighter than in Tayassu angulatum (typical). The pre- 

 molars are usually quadritubercular with one of the inner tubercles 

 often obsolete. The posterior molar is smaller and less roughened 

 by needle-like subsidiary tubercles. .The skull itself is slightly 

 broader than that of T. angulatum. (See figs. 4. 5, and G.)

Life history. — Skins of peccaries killed in the Apache Mountains 

 near Monument No. 40. Mexican Boundary Line, were the first unmis- 

 takable evidence seen of the existence of these animals as we pro- 

 ceeded westward from the Rio Grande. Specimens were subsequently 

 taken in the San Luis, Guadalupe, and Santa Cruz mountains. 

 and in the valley of the San Bernardino River. On the San Luis 

 Mountains they were found from the lower edge of timber up to the 

 highest summits, ;i> well as on those parts of the surrounding plains 

 and playas where the nolinas. mesquites, and mimosas grew abun- 

 dantly. 



We found evidences of the former presence of peccaries in the 

 Iluachuca Mountains, Arizona, where soldiers under the command of 

 ('apt. Louis A. Craig killed some of them a few years before. Speci- 

 mens were seen in L892 in the collection of Col. \l. V. Hafford, at 

 Tombstone, Ai izona. 



Maj. E. K. Otey, of Prescott, Arizona, found peccaries in the Mule
