Hunting Horned Dinosaurs 81 



far as I know this is the most complete skull 

 known of this species. While at work on my 

 specimen I learned some remarkable things. 

 There is always an opening between the horns of 

 these saurians. In Triceratops, it is midway be- 

 twccn the end of the beak, and the crest. In this 

 specimen, however, it is two feet from the end 

 of the beak, and three feet to the further end of 

 the crest. Then, though the skull proper in front 

 of the crest is quite heavy and strong, and with 

 large mandibles, and rather a large horn over the 

 nose, as compared with the small ones over the 

 eyes. The crest seems to be built for strength, 

 as the central bar, the side and distal bars are 

 strong, but beveled off to the large openings ; and 

 masses of bone are scooped out of the skull- 

 adapted evidently to add to the strength, but to 

 reduce the weight. This is not to be wondered 

 at, when we study the skeleton. For we find the 

 neck -crest not only covered the neck and shoul- 

 ders, but extended back over seven of the dorsal 

 vertebrae, to within a few inches of the pelvic 

 arch. I do not think the animal was much big- 

 ger than a cow : about 9 feet from beak to drop 

 of the tail; and the latter was short, barely 

 dragging on the ground. When cutting a path 

 through the dense sub-tropical foliage of reeds, 

 rushes and grass, with many a bog, he simply 

 parted the rank vegetation with his triangular- 

 shaped head and crushed it under his four large 

 spreading feet. But when he was attacked,
