38 MUSEUM OF COMPARATIVE ZOOLOGY 



the mastodon, the imperial elephant was far larger — in fact, the 

 largest elephant known. 



In general this room is only partially installed, and will in time be 

 largely rearranged. Noteworthy specimens are the sabre tooth tigers, 

 the evolutionary series of the fossil horses to show their increase in 

 size and the reduction of the number of digits, the well-preserved 

 three-toed horses, Mesohippus, the Scott and Osborn types of Titano- 

 theres. The Moropus represents a group of mammals known as the 

 Chalicotheres, which showed some relationship with existing her- 

 bivorous animals, and which had great claws instead of hooves, for 

 what purpose is unknown. The two fine Irish Elk skulls, one on the 

 wall and one with its complete skeleton, are impressive remains of the 

 largest deer known. 



Upper Entry Hall 

 This hall contains the Phillips Collection of Antlers and Horns. 

 Here are not only many record heads, but a series, finely chosen, to 

 enable one to appreciate the extraordinary diversity shown among 

 the wild cattle, sheep, goats, deer and antelopes. 



Main Hall 

 This hall contains a synoptic collection of Mammals. Attention is 

 called to the charts on the walls which show the interrelationship of 

 the various mammalian groups and the location of these groups in 

 the cases. The specimens to which the visitor's attention is particu- 

 larly directed are: the splendid Mountain Gorilla; the Pere David's 

 deer, extinct in a wild state; the Javan Rhinoceros, the rarest of all 

 living allied species; the Okapi, the first ever brought to America; 

 the Giant Giraff"e and the European Bison, also on the verge of extinc- 

 tion. The Pygmy Hippopotamus from Liberia is a rare species and is 

 shown with its skeleton, while the Zebra represents a race which is 

 now extinct and which formerly inhabited the southern portion of 

 the Cape Province, South Africa. 



The Gallery of Birds 

 Surrounding the three great whale skeletons is the new synoptic 

 collection of birds. This shows skeletons and mounted representa- 

 tives of all of the principal families of the birds of the world.
