Between 1922 and 1928, Museum Trustee Arthur S. Vernay and British Colonel John C. Faunthorpe conducted six expeditions to collect animal specimens in India, Burma (now Myanmar), and Siam (now Thailand). The specimens were then donated to the Museum and formed the foundation for this hall, which opened in 1930. The mounting of the animals in the Hall of Asian Mammals was overseen by James L. Clark using Carl Akeley's methods, and the hall's layout is similar to that of the Akeley Hall of African Mammals. As in the Akeley Hall, a group of elephants forms the centerpiece. These complementary exhibits allow the visitor to note the differences between the two types of elephant: The Asian elephant is generally smaller in size, with smaller ears and a higher forehead. The animals featured in this hall also include the water buffalo, gaur, leopard, and rhinoceros, and many represent species threatened by poaching and loss of habitat. Two examples of Asian mammals, the Siberian tiger and the giant panda, were among the animals relocated to the Endangered Case in the Hall of Biodiversity when it opened in 1998.
