pseudofronds, and extending only a short distance below the 

 collar. 



The general figure, now given, is based on a sketch from 

 life, by F. H. Bradley, of the original type, corrected by com- 

 parison with the preserved specimen, which was from Panama.

The collar of this "West Indian species is very broad and is 

 covered with about 24 pseudofronds, or groups of small folds 

 and lobulated and crowded actinobranchs, much more complex 

 than in either of the preceding species. 



Asteractis formosa (Duch. and Mich.) Ver.

This is closely allied to the preceding species, but has smaller 

 and less complex groups of lobulated actinobranchs on the 

 collar and fewer tentacles. Guadaloupe.

This remarkable genus is characterized by having a series of 

 about six (sometimes 5 or 8) large, dichotomously branched 

 fronds, or branchiae {actinobranchim) exterior to the tentacles. 

 The species examined by me has, on these fronds, at the forks, 

 many more or less spherical bodies having the structure of 

 acrorhagi. There are numerous mesenteries, most of them 

 perfect and bearing gonads. Sphincter muscle feebly devel- 

 oped or wanting. 



The genus Actinodactylus Duch., 1850, was based on A. 

 Boscii D., which may, perhaps, have been only a young 

 Lebrunia. It was only 4 to 5 lines in diameter, with 15 small, 

 simple tentacles, in a single circle, and with 5 elongated, pedi- 

 celled, trilobed fronds, the lobes with small subdivisions. It 

 may, however, prove to be a distinct genus when larger exam- 

 ples can be studied.
