Pentaceratops^ No. 12,743 U.S.N. M., supraorbital horn and parts ol squamosal, collected by <>■ F. 



Sternberg in 1929, from the Kirtland formation, in S. \Y. J4, Township 24 N., Range 12 W., 

 San Juan County. 



Pentaceratops sternbergn\ type, No. 6325 A.M.N.H., skull and skeleton (skeleton discarded), col- 

 lected by C. H. Sternberg in 1922, 9 miles northeast of Tsaya, from the Fruitland formation. 



Pentaceratops st ember git, No. 1624 A.M.N.H., skull with half of frill gone, collected by C. H. 

 Sternberg in 1923, from the Fruitland formation near Tsaya. 



Pentaceratops fenestratus, types, (A) skull, without lower jaw; ( B) skeleton almost complete, lower 

 jaw; discovered by C. H. Sternberg in 1921, 1 mile south of Kimbetoh wash, on the south 

 branch of Myers Creek, in the Kirtland shales. The material is now at I 'psala, Sweden. Sent 

 along with this material were two pieces of a squamosal and part of a parietal ( Pentaceratops] ) 

 which were found on the south branch of Meyers Creek, 4 miles above Cattle Ranch, and also 

 from the Kirtland formation. There was also included the lower part of a squamosal, the 

 distal part of a quadrate, and the proximal part of a supraorbital horn about 35 cm. long. 

 These latter bones were found in the Fruitland shales, by C. H. Sternberg, on the south side 

 of Alamo Wash, 3 miles above Hunter's store. 



Pentaceratops, No. 1625 A.M.N.H., rear part of crest, collected by C. H. Sternberg in the Fruit- 

 land formation in 1924. 



Ceratopsian, No. 1622 A.M.N.H., skull, from the Fruitland shales, near Tsaya, collected by C. H. 

 Sternberg in 1922. 



The following ceratopsian material is in the U. S. National Museum: 



Ceratopsian, a fragmentary skull, collected in Barrel Spring Arroyo, about 1 mile southwest of Ojo 

 Alamo store in the Ojo Alamo sandstone. 9 



Ceratopsian, fragments of teeth, found in the Ojo Alamo sandstone, 10 on the north side of Barrel 

 Spring Arroyo, about 1 mile south of Ojo Alamo store. 



Ceratopsian, fragments of a ceratopsian frill, not determinable, found on the north side of Barrel 

 Spring Arroyo, about \ l /z miles southwest of Ojo Alamo store, in the Ojo Alamo sandstone. 



Ceratopsian, fragments of a frill, found on the north side of Barrel Spring Arroyo, 1 34 miles south- 

 east of Ojo Alamo store, in the Ojo Alamo sandstone. 



Ceratopsian, fragments discovered by J. H. Gardner of the U. S. Geological Survey in 1908, near 

 the head of Coal Creek, 1 mile southeast of Ojo Alamo. 



Ceratopsian, teeth, found in 1915 on the north side of Barrel Spring Arroyo, ]/i mile west of the 

 wagon road from Ojo Alamo, in the Ojo Alamo sandstone. 



Locality 20 (Fig. 2) is situated in the Red Beds of the Rio Grande region, at Elephant Butte. 

 The only record of Ceratopsia from here is of some Trkeratops bones, consisting of a few frag- 

 mentary vertebrae identified by J. W. Gidley. 11

Locality 21 (Fig. 2) is in the Big Bend of the Rio Grande, near the Chisos Mountains. In 

 the Upper Cretaceous Rattlesnake beds exposed here there was discovered the lower extremity of a 

 tibia, which was identified by Williston 12 as ceratopsian, but considered by the author as scarcely 

 sufficient for determination. However, it is indicated as a possible locality.
