Kange from 56 to 262 fathoms, in twenty-seven stations, off Santa Cruz, Saba 

 Bank, Montserrat, Guadeloupe, Dominica, Martinique, St. Vincent, Grena- 

 dines, Grenada, and Barbados. 



Madraeis asperula Edw. & H. 



Kange from 60 to 248 fathoms, in six stations, off Santa Cruz, St. Kitts, 

 St. Vincent, and Grenada. 



Solenosmilia variabilis Dunc. 



None of our specimens show the blue coloration noticed by Prof. Duncan in 

 northern specimens. 



Range from 120 to 452 fathoms, in six stations, in Old Bahama Channel, off 

 Montserrat, Guadeloupe, St. Lucia, Grenadines, and Barbados. 



Lophosmiiia rotundifolia Edw. & H. 



There is a fine series of specimens of all ages, which positively contradict 

 Duchassaing's opinion that the original specimen of M.-Edwards and Haime 

 was the young of a compound coral, which he has unnecessarily re-named 

 Oxysmilia rotundifolia. Occasionally two or three individuals grow in a 

 group, but are not to be called compound for that reason. The lamellar three- 

 lobed columella is rarely seen as regular as in M.-Edwards and Haime's 

 figure ; it usually thickens in the old, and often becomes irregular. The foot 

 thickens very much by additions of exothecal cellular roots arranged in con- 

 centric circles, as in Thecocyathus. The dissepiments are few, but rather thick. 



Lophosmiiia urena Duch. is probably the same. 



Range from 42 to 163 fathoms, in eight stations, off Santa Cruz, Montserrat, 

 Dominica, Grenadines, and Barbadoes. 



DASMOSMILIA Pourt. nov. gen. 



Corallum turbinate, with very thin wall, false palli and columella formed by 

 lobes of the septa ; rudimentary endotheca. 



This genus is proposed to receive the two species heretofore named by me 

 ParasmiUa Lymani and Parasmilia variegata, which evidently differ very much 

 from the typical Parasmilia. The figure of one of the septa of P. Lymani in 

 my " Deep-Sea Corals," PL VI. Fig. 10, represents well the principal generic 

 character.
