Figure 4 

 This Bahama Reef habitat group was adapted, by kind permission, from an 

 exhibit in the American Museum of Natural History in New York. It gives 

 striking evidence of the abundance and variety of marine life. Forming the 

 base of the group is a living Bath Sponge (Euspongia), and to the back and left 

 several vase-shaped Sponges of the genus Spinosella are seen. Three Corals 

 are shown ; the Brain Coral (Meandra) with an Echinoderm, the Brittle Star 

 (Ophiura), crawling along the side; to the right and back, Millepora extends 

 toward the top of the figure ; and the calcareous Bush Coral (Oculina) in the 

 left foreground. The beautifully marked tropical fish is Chaelodon.
