INVERTEBRATE ZOOLOGY 
to bring out more clearly the structure of these animals, and their 
relation to man, large models, carefully constructed, have been pre- 
pared. This is especially true in the lowest group of the animal king- 
dom, namely— the Protozoans. The models are constructed in wax and 
glass, and are worked out wath the most careful detail. 
The sponge collection represents extensively the forms found in 
Bermuda, the Bahamas, and Japan. Almost all of this material, 
excepting that from Japan, was collected by Professor R. P. Whit- Sponges, 
field. A series of siliceous sponges from Japan, containing exception- 
ally fine examples, was purchased in 1901. The collection contained 
thirty-seven specimens, representing twenty-six species. 
The superb collection of corals is representative of the forms found 
in the East and West Indies, Bermudas, Bahamas, Hawaiian Islands, 
New Zealand, and Florida, and have been acquired largely through 
the generosity of Mr. Percy R. Pyne, Mrs. R. P. Dana, Mr. D. Jackson 
Steward, the Pacific Mail S. S. Company, Dr. D. Bryson Delavan, and 
Professor R. P. Whitfield. One hundred and twenty-five unusually 
fine specimens from Florida and the Pacific Ocean were given by Mr. corais. 
Pyne in 1885. Some beautiful forms were contained in a collection 
from the West Indies, given by Mrs. R. P. Dana, and from the 
East Indies by Mr. D. Jackson Steward. Most of the corals from 
Florida, Bermuda, and the Bahamas were collected, and many 
presented, by Professor R. P. Whitfield. Of special note is the 
specimen of Madrepora palmata, which is probably the finest ever 
collected, and the unusually large and perfect specimen of Orbicella 
annularis. 
A representative series of corals from the Hawaiian Islands was 
obtained on an expedition by Dr. J. E. Duerden in 1905, when 1,500 
specimens representing between thirty and forty species were col- 
lected, forming probably the largest collection of Hawaiian corals ever 
made. 
An expedition to the Bahama Islands in 1908 under Dr. William 
Morton Wheeler in search of material for use in a coral reef group 
yielded manv choice specimens of corals, including an exceptionally
