A NEW PHYTOSAUR FROM THE TRIAS OF ARIZONA 145 



have come from the Triassic of Gua- 

 daloupe County, near Santa Rosa, 

 New Mexico. 



The material collected consists of 

 a few large, well-preserved pieces of 

 bone representing a fairly complete 

 skull (Fig. i). In the skilful hands 

 of Paul C. Miller the missing por- 

 tions have been restored in plaster 

 and the major features are almost 

 as certainly determined as though 

 all the fragments had been collected. 

 On both the dorsal and the ventral 

 sides the skull is complete along the 

 median line save for the occipital 

 condyle proper. On the right side 

 the jugal, except for the portion that 

 forms the posterior border of the 

 antorbital fenestra and the process 

 that takes part in the border of the 

 orbit, is missing, as is the quadra- 

 tojugal, the squamosal, and all but 

 the anterior end of the postorbital. 

 On this side, too, the outer end of 

 the paroccipital and the quadrato- 

 pterygoid bar are missing. On the 

 left side the missing portions are 

 much the samxe as on the right, 

 except that the restoration extends 

 farther forward. On the left side 

 the posterior end of the jugal and 

 all of the quadratojugal are pre- 

 served. 



The skull (Fig. i) is large, about 

 865 mm. long, and massive. It is a 

 crested form of the "broken out- 

 Kne" type. From an oval cross-
