HISTORY OF THE MUSEUM 
fine example of Madrepore coral, measuring ten feet across and weigh- 
ing nearly two tons. 
A series of hydrozoans and actinozoans, containing forty-seven 
specimens mounted in alcohol and representing the marine life of the 
Bay of Naples, was received in 1896 as a gift from Mr. William E. 
Dodge, 2d. 
The other groups of invertebrates, namely, the echinoderms, an- 
nulates, and arthropods (aside from insects) are represented by typical 
specimens, although our collections are not extensive. The structure 
and anatomy of the more complicated invertebrates, such as the clam 
and the oyster, are shown by models enlarged six to seven diameters. 
Models have also been prepared showing the consecutive stages 
in the development of the eggs of different forms, namely: mollusk, 
brook trout, frog, and lancelet. These series, in each case, embody 
the researches of investigators in their particular subjects and are 
prepared under their supervision or from their published works. 
To bring out more clearly the relation between man and the lower 
animals, a series of models, illustrating the development and structure 
of the Malaria Mosquito and the life cycle of the Malaria Organism, 
has been prepared. 
The Marine Habitat Groups represent the typical life of several 
marine species. These include sea urchins, brittle stars, land crabs, 
and sponges. 
Marine invertebrate material acquired through expeditions, in 
addition to those previously mentioned, includes many species of sea 
fans, gorgonias, crustaceans, etc., from Bermuda, and echinoderms, 
sea anemones, sea cucumbers, starfish, etc., from the Bahamas, all 
collected and presented by Professor R. P. Whitfield; actinians and 
alcyonarians from the West Indies, collected by Dr. J. E. Duerden; 
sea fans, etc., from the Bahamas, collected by Professor William 
Morton Wheeler; sea urchins, etc., from Newfoundland, collected 
by Mr. L. P. Gratacap; and other invertebrate material from Massa- 
chusetts, Florida, New Mexico, Alaska, Patagonia, Siberia, and the 
Philippine Islands.
