BARBADOS-ANTIGUA EXPEDITION 105 
branches where there is no intervening ccenenchyma. Lower 
down on the branches the calyces are counter-sunk in the gen- 
eral surface with evident ccenenchyma between. The septa are 
usually ten in number, a most uncommon feature in recent cor- 
als. Occasionally there are only eight, and in one case twelve 
were counted. Nine out of ten, however, have the ten septa, 
and that number seems characteristic of the species. 
The most marked difference between this form and any of the 
Oculinide, however, is its spongy and porous structure and 
noticeably light weight, wholly unlike the unusually dense and 
solid structure of any branching Oculina that I have seen. In 
this respect it resembles most clearly certain species of Pocillopora 
from the Pacific; but from these it differs in still more important 
respects. Another fine specimen is allied to Meandrina. It is 
a cylindrical colony about nine inches high and four inches in 
diameter and has a regularly rounded top. The surface is cov- 
ered with a very intricate labyrinth of confluent calyces, much 
as in Meandrina sinuosa, but the furrows are very much nar- 
rower, giving the appearance of vermiculation. This species is 
doubtless well-known, but although I have seen specimens in the 
hands of curio dealers, I have never seen one with a label show- 
ing the name. Miss Van Wagenen tells me that there is one in 
the National Museum, but here again the label seems missing. 
It is uncommonly beautiful form, reminding one of the carved 
marble pillars bearing busts and found in the central court of 
some of the houses at Pompeii. 
The red coral, which is often brought up from deep water 
by fishermen, much resembles the figure of Amphihelia rostrata 
given by Agassiz in his ‘‘Three Cruises of the Blake,’’ vol. II, 
page 152. It is a very beautiful coral, red instead of white, 
and the branches and calyces are much more delicate than in 
the figure. It sometimes forms colonies nearly a foot in height. 
Quite a number of simple corals were secured by dredging. 
They are all, however, small and inconspicuous forms and offer 
little of general interest. 
Actinians.—The anemones, or ‘‘animal-flowers’’ as they are 
called at Barbados, were quite abundant in shallow water near 
Pelican Island. Miss Van Wagenen had charge of this group 
and has placed her notes at my disposal. Owing to her care,
