46 CORALS AND CORAL ISLANDS. 



The Caryophyllia here figured is one of the solitary species 

 of the tribe found in European Seas, and on the coast of 

 Great Britain. The figure is from Gosse's " British Actinology." 

 It also grows much longer in proportion to the breadth. The

figure to the right is of one unexpanded. One of its lasso- 

 cells, in different states, is shown in figures 3, 4, 5, on 

 page 13. 



The corallum of a related species is given on page 22. The 

 walls and , septa are remarkably solid. This species, the 

 Caryophyllia cyat/ms, has been found not only in the Mediter- 

 ranean, but also at the Azores. Another species, the C. davus, 

 has a wide distribution, occurring in deep water in the 

 Florida straits and off the British coasts as well as m the 

 Mediterranean. 



Another example of this tribe, as defined by Professor 

 Verrill, is the species of Astrangia occurring alive along the 

 southern shores of New England, and on the coast of New 

 Jersey. Specimens are not uncommon in the vicinity of New 

 Haven, on the rocks by the Light-House, and at other places 

 in Long Island Sound, and when alive it is an exceedingly 

 beautiful object. The accompanying figures of the animal are 

 from the drawings made to illustrate a yet unpublished memoir 

 by Professor Agassiz. They are copied from the "Sea-Side 

 Studies" of Mrs. Agassiz and Alexander Agassiz. In figure
