In the Dinosaur Hall (No. 407 of the Fourth Floor) the Trachodon 
group described in the April number of the JouRNAL has been com- 
pleted by the addition of the second skeleton and by the insertion in the 
base of fossils and models showing the shells and plants belonging to a 
mud flat of the period (Cretaceous) when the animals lived, together 
with fossil leaves of trees growing along the bordering mainland. Sey- 
eral beautiful transparencies representing the Cretaceous Bad Lands 
and the Triassic and Jurassic bluffs in Montana and Wyoming from 
which have been obtained many of the dinosaur remains making up the 
exhibitions in the hall have been placed in the east windows. 
In the Hall of Fossil Mammals (No. 406 of the Fourth Floor) several 
important additions and changes have been made during the past few 
months. A specimen of the four-toed horse (Orohippus osbornianus 
Cope) from the Middle Eocene beds of the Bridger Basin, Wyoming, 
has been placed on exhibition. ‘This was a small animal of about the 
same size as its ancestor in the Lower Eocene beds. It had four toes 
in the fore feet and three in the hind feet, but there are no vestiges of the 
fourth toe remaining. Last year’s expedition to Egypt is brought to 
mind by an exhibit consisting of the skull and lower jaws of the Horned 
Arsinoithere. ‘This gives one too some hint of the strange appearance 
of one of the animals inhabiting northeastern Africa in Upper Eocene 
time. ‘The large skeleton of the great Sabre-Tooth Tiger, Smilodon, 
from the Pleistocene beds of South America has been put into a case by 
itself, in which is also exhibited an oil painting by Charles R. Knight 
representing the animal as it is supposed to have appeared in life. ‘There 
has been placed in the Amblypod Alcove at the west entrance to the hall 
a splendid composite skeleton of Uintatherium. This was a huge four- 
toed, elephantine, hoofed animal with large dagger-like tusks. 
Dr. Epmunp Otis Hovey, Associate Curator of Geology, who visited 
the West Indies for the Museum immediately after the eruptions of Mt. 
Pelé and the Soufriére in 1902, and went again in 1903, made a third
