This rather large species has the disk covered with a soft, smooth 
skin, without plates. Its colors are usually bright or dark yellow, 
orange, or greenish varied with yellow. It may become 6 to 8 
inches across. Conceals itself in crevices of the reefs and under 
dead corals. Ranges from Florida to Brazil.

This singular species has only occurred clinging to the large stony 
gorgonian, Verrucella grandis, taken in about 100 feet of water on 
the outer reefs. It is rough and so annulated with lighter and 
darker brown that it closely resembles the gorgonian branches. 
CRINOIDEA. 
Antedon, sp. Young. 
A single specimen, too young for accurate identification, was 
obtained in 1901.
