THIRD FLOOR 
The corridor (No. 305) contains the Osprey Group. The 
birds, nest and accessories forming this group were obtained 
on Gardiner’s Island, where exists the largest colony of Ospreys 
or Fish Hawks known within 100 miles of New York City. 
Turning now to the east the visitor finds himself in Hall No. 
306 which is devoted to mammals and insects. The mammals 
installed in this hall are mostly Old World ungu- 
lates, marsupials and edentates. 
Mammals. 
The cases along the top of the gallery railing are devoted to 
insects. At the right (south) is part of the general collection 
of Butterflies. Silkworm Moths, Cecropia and other 
moths are directly in front of the entrance. One case 
contains specimens illustrating the protective coloration of 
insects. The next case shows protective mimicry. Among the 
Beetles particular attention will be attracted by the Longhorns 
or Cerambycidz, the Leafhorns or Scarabeidze (among which are 
the Hercules Beetles from the West Indies, Mexico and Africa), 
the Staghorns or Lucanidz, and the Sawhorns or Buprestide. 
The last have wing-cases which are remarkable for their green 
iridescent colors.
