of bone, that were arrang-ed like chain armor giving: mobility to the skin. 

 In this specimen they may be seen for the first time in place. I have 

 seen a pelvic arch of one of the huge creatures six feet across. Some of 

 the ribs are over five feet long. 



We secured three Ceratops skulls, one of them new. This last is re- 

 markable for its beautiful crest. It is oblong in form, measuring 2 feet 

 11 inches from the back margin of the orbital opening to the distal end, 

 and it is 28 inches wide. The armature along and behind on the margins 

 of the crest are remarkable, and must have been covered with horn, 

 and made a very formidable weapon of defense. This is No. 48 of my 

 collection. 



No. 17 is a very beautiful section of the body, taken from a mold 

 made soon after burial in the clayey sands that covered it. A cast was 

 taken at burial. As the organic remains shrunk and decayed, sand, 

 taking its place, took a perfect cast of the original body. Even the 

 wrinkles of the skin, the shadowy marks of the ribs below, the form of 

 the muscles, and the fat layers along the back, are as perfectly repro- 

 duced as if the dead saurian lay before us. Over six square feet of 

 back and flanks are present in hard iron stone. That will last forever 

 and a day. This is a specimen of the peculiar Stephaiiosaiirus mar- 

 ginatus Lambe, of which species I had the honor to discover the type 

 in these beds in 1913. 



The specimens enumerated above were sold to the American Museum 

 of Natural History, New York, on the recommendation of Barnum 

 Brown, who came here last Christmas to see them. 



Another fine specimen is of the crested duck-bill Corythosaurus 

 casua7-ius B. Brown. The type, now mounted in the American Museum, 

 New York, is the finest specimen of a duck-billed dinosaur known. It 

 was preserved in a swimming posture, and with the "mummy" I sold 

 to the Amierican Museum, prove conclusively what I have always be- 

 lieved, the trachodonts are swamp-swimming and feeding reptiles, in- 

 stead of land, tree-browsing reptiles, as taught by Cope and Marsh. 



I have a fine skull. The predentary and a small part of the back of 

 the high crest are missing. It is 2 feet long and 22 inches high in the 

 center of the crest, which is like a helmet, with narrow ridge in center. 

 Or like the Cassowary, from which resemblance Barnum Brown gave 

 it its name. There are eleven continuous vertebrae back of the head, and 

 four scattered dorsals, and twenty-four caudals. The complete sacrum, 

 from under part of centrum to top of spine, is 16 inches. Both illia, 

 pubic bones and ischia are present, the latter with large footed distal 

 ends, and are 3% feet long, with both femora, SVz feet long, tibia and 

 fibula, 3 feet 3 inches long, and two metatarsals and three phalanges. 

 The scapula is 2 feet 7 inches long; its greatest width 8^/^ inches, 

 humerus 21 inches long. This specimen is No. 6, and was discovered by 

 my son, Levi, a few rods from the carnivore. 



We have a skull I discovered of Stephavosaiirus ynarginatus (I also 

 discovered the type in 1913 with much of the skin impression). The 

 Maxillae and dentaries show a beautiful series of teeth, both functional 

 and the successional. There are at least 2,000 teeth in this species. It
