On the Anatomy of Distichopora—with a monograph 
of the genus

[Read before the Royal Society of N.S.W., 6 August, 1879.] 
Tue family of the Stylasteride has attracted so much attention 
lately in connection with the deep-sea ings, impor- 
tant researches of Mr. Moseley, naturalist to the “ Challenger,” that 
need offer no apology for these brief researches on one of the 
least known of the family—the genus Distichopora. As far back 
as 1859 I sent specimens of this singular coral to naturalists in 
England, who could give me no information concerning them. 
The species sent home was described by Dr. Gray,* but beyond 
unknown as the fossil. This led me to send many specimens to 
urope, seldom, however, with any satisfactory result. I then 
Saw that the work must be done, as far as it could be done, by 
Colonial naturalists, 
e of my earliest puzzles was Distichopora. As early as 1858 
T made some of the drawings which illustrate this paper, and I 
arrived at some of the conclusions which I embody here. As soon 
as Thad seen the results of Agassiz’s studies on the genus Millepora 
T came to the conclusion that Distichopora was one of those forms
