8 THE AMERICAN MUSEUM JOURNAL 
presents several unusual features, notably the distinct sutures which clearly 
define every element of the skull and the definite size and position of the 
orbit. 
The present arrangement is temporary. As soon as the skeletons 
can be restored and the missing parts in each modeled or cast, the one 
eroup cons'sting of the two 
D 
from the other, it is intended to make a g 
Tyrannosaurs standing over the mummied carcass of a ‘Trachodon, a 
unique specimen which was purchased last year from Mr. Charles H. 
Sternberg and noticed in the JOURNAL for April, 1908. This group will 
make a very effective and striking centerpiece for the Hall of Cretaceous 
Dinosaurs which is planned for the future development of the Museum. 
There is no living beast of prey that compares with the great car- 
nivorous dinosaurs or which habitually attacks the largest herbivorous 
animals. The lion and the tiger prey upon the medium-sized and 
smaller hoofed animals; they do not usualiy molest the great “pachy- 
derms’’ (the elephant and the rhinoceros), and the indefinite multi- 
plication of these giant ungulates is checked by other means. But 
during the Age of Reptiles it was different. "The Allosaurus of the 
Jurassic, the Tyrannosaurus of the Cretaceous, were fitted by nature to 
attack and prey upon the largest of their herbivorous contemporaries ; 
and the size and power of their weapons for attack far surpass anything 
seen among modern carnivores or those of the Age of Mammals. Con- 
versely the largest herbivorous dinosaurs wore armor or weapons for 
defense much heavier and more powerful than can be found among the 
great pachyderms of modern times, whose thick skin is mainly a protec- 
tion against accidental injury or the attacks of insects. he great horns 
and bony neck-frill of Triceratops and the armor-plated head and body 
of Ankylosaurus were developed no doubt to resist the attacks of the 
huge Tyrannosaur. Other contemporary dinosaurs like Trachodon 
were unarmored but were evidentiy adapted to a more amphibious life 
and sought refuge in swimming beyond the reach of their great enemy. 
Others again of much smaller size were agile and active and probably 
escaped by superior speed. 
Mr. GEorGE S. Bowboln, one of the Trustees, has presented to the 
Museum a fine o'd native basket from the Hope Isiands in the South 
Pacifie Ocean.
