Tayassu Fischer. 



1. Lower anterior portion of face 

 broader than middle anterior portion, 

 a feature produced by a sharply de- 

 fined overhanging ledge formed by the 

 lateral swelling out of a ridge of the 

 maxillary, commencing on the inner 

 side of the infraorbital foramen and 

 extending forward to the alveolus of 

 the canines. 



2. Upper posterior portion of face 

 relatively broad and moderately 

 curved laterally. 



3. Outer surface of the jugal below 

 orbit moderately expanded and nearly 

 flat ; its inferior external border form- 

 ing an acute ridge which is continu- 

 ous but not in a direct line with that 

 of the maxillary which it meets at a 

 distinct angle, the latter continuing 

 forward and upward disappears above 

 and considerably behind the canine. 



4. Orbito-frontal foramina opening 

 superiorly, relatively close together, 

 directly above the anterior border of 

 the orbit, the deep sulci leading for- 

 ward away from them in distinctly di- 

 verging lines. Anteriorly they slope 

 gently downward on the sides of the 

 face and disappear near the anterior 

 extremity of the maxillary ridge. 



5. Space between incisive border 

 and canine not laterally constricted; 

 the extreme anterior border of the 

 maxillary swelling outward at the for- 

 ward border of the canine forms a 

 shallow depression for the reception 

 of the point of the moderately long 

 iower canines. 



6. Cheek-teeth with relatively low, 

 broadly cone-shaped main cusps, and 

 prominent intermediary cusps ; the 

 last premolars above and below almost 

 completely molariform and p' above 

 submolariform. Canines relatively 

 short, the upper ones thin and much 

 extended anteroposteriorly with their 



Pecari Reichenbach. 

 1. Lower anterior portion of face 

 narrower than middle anterior por- 

 tion. No lateral swelling of the max- 

 illary in this region. 



2. Upper portion of face relatively 

 narrow and strongly arched laterally. 



3. Outer surface of the jugal below 

 orbit relatively shallow, its anterior 

 portion depressed to form a shallow 

 pit, or depression at the anterior in- 

 ferior border of the orbit ; inferior ex- 

 ternal ridge of jugal continuous in a 

 direct line with that of the maxillary ; 

 the latter extending forward and but 

 slightly upward, disappears in a 

 small lateral prominence directly 

 above the canine. 



4. Orbito-frontal foramina opening 

 superiorly, relatively well apart and 

 farther back than in Tayassu, the 

 sulci leading from them first converg- 

 ing forward for about one-half their 

 length, then diverging they pass for- 

 ward and finally recurve abruptly 

 downward to the border of the maxil- 

 lary ridge. From the extreme anterior 

 points of these curves a second pair 

 of sulci continue forward along the 

 sides of the face to the upper border 

 of the nasal notch. 



5. Space between incisive border 

 and canine latterally constricted ; the 

 extreme anterior border of the maxil- 

 larly modified to form an angular but- 

 tress, past which the posteriorly trun- 

 cated points of the longer lower ca- 

 nines bite. 



6. Cheek-teeth in unworn condition 

 with relatively high and pointed main 

 cusps; intermediary cusps usually in- 

 cipient, tending to form lophs ; last 

 premolars above and below submolari- 

 form all premolars tending toward 

 the molariform pattern, but all are 

 more simple than in Tayassu; canines
