the individual. In the 3 weeks of continuous work required to exca- 

 vate and prepare the bones for shipment to the National Museum 

 about one-third of the skeleton was recovered. 



Another specimen found in these same deposits, also worthy of 

 special mention, is the disarticulated skull and parts of skeleton of a 

 horned dinosaur. When the scattered elements are prepared and 

 assembled it is estimated the skull will have a length of more than 

 6 feet. It appears to represent a form new to science, and further 

 interest attaches to this discovery as it greatly extends the western 

 geographical range of the Ceratopsia in North America. 



Later in the season special search was made of the overlying beds, 

 in which a single skull fragment of a mammal had previously been 

 found by Messrs. Reeside and Spieker. This work was rewarded by 

 the recovery of a small collection of identifiable skull and jaw frag- 

 ments carrying teeth, which was sufficient to indicate definitely for 

 the first time the Paleocene age of this part of the geologic section. 



Just as the season drew to a close in this area, the discovery of six 

 more or less complete articulated skeletons of a small lizard made a 

 fitting climax to our explorations. These lizard specimens represent 

 an undescribed form, and they so thoroughly supplement one another 

 that a knowledge will be gained of practically the entire skeletal 

 anatomy. These specimens are among the oldest lizards known from 

 North America and the most perfectly preserved of any yet discovered. 



The work of collecting in this area, especially of dinosaurian re- 

 mains, was particularly arduous. The steepness of the exposures, 

 the 8,000-feet elevation, and the inaccessibility of much of the terrain 

 to the motor car, added much manual labor to the collector's task. 



On August 1, after having boxed and shipped the collections made, 

 we proceeded by motor from Price, Utah, to Holbrook, Ariz., where 

 according to our original plan for the season's work, 3 weeks were 

 spent in the exploration of the Chinle division of the Triassic for its 

 fossil vertebrates. 



Here most of our work was in the badland areas bordering the 

 Petrified Forest. Our work here was greatly facilitated by the gen- 

 erous assistance given by Ranger Naturalist M. V. Walker of the 

 National Park Service. In the short time at our disposal we were 

 fortunate in accumulating a representative collection from the Chinle, 

 material that was badly needed to round out the Triassic part of the 

 paleontological collections of the National Museum. Three phytosaur 

 and two stegocephalian skulls are worthy of special mention. 



In all, the specimens collected on this expedition filled 13 large 

 cases, which had a combined weight of 5,729 pounds.
