to note in this connection that the strong infusion of arctic forms 

 found in reporting on the Hydroida of the Hawaiian region « is not 

 to be found in the alcyonarian fauna. The Pennatulacea is a group 

 mainly found in deep water in all seas, and its occurrence in this col- 

 lection was to be expected, although the number of new species is 

 rather larger than might have been anticipated. The most notable 

 fact in regard to the Gorgonacea is the entire absence of representa- 

 tives of the great family Gorgonidse, the scarcity of the Briareidse, 

 and the surprisingly rich representation of the Primnoidse, and par- 

 ticularly of the Chrysogorgidse, which leads the list of families with 

 17 species, exactly one-fourth of all the species found, 9 of which 

 are new. 



In order to show the general facies of the alcyonarian fauna of 

 the Hawaiian region the following synopsis is presented:
