I have examined several large and characteristic examples of this 

 species from the outer reefs of the Bermudas and also from the reefs 

 in Great Sound, etc. Good specimens are in the American Museum, 

 New York, and in the museum of the University of New York. The 

 latter were obtained by Prof. Bristol's party. We obtained but one 

 example. 



The color in life is dull yellow. It does not differ from the 

 Florida form. 



Orbicella cavernosa (Bsp.) Dana.

Orbicella cavernosa Yerrill, Bull. Mus. Comp. Zool., I, p. 47, 1864. 



The only specimen studied by me is a large hemispherical mass, in 

 excellent condition, which formed part of the Bermuda exhibit, sent 

 by the Governor of Bermuda to the Centennial Exposition at Phila- 

 delphia, in 1876, and afterwards presented to the U. S. National 

 Museum. It is said to be not uncommon on the outer reefs near 

 North Rocks. 



Plesiastreea Goodei, sp. nov. 



Plate LXVII. Figure 1. 



Coral solid, massive, hemispherical, calicles circular, not very deep, 

 pretty regularly arranged, near together, with their margins a little 

 prominent and thickened. Septa prominent, nearly entire, usually 24, 

 of which 12 are broad, reaching the columella, and alternate with 12 

 much narrower ones that extend only one-third the distance. The 

 larger septa are vertical within, distinctly thickened distally, and 

 bear thickened paliform lobes at the inner edge, close to the columella.
