BARBADOS-ANTIGUA EXPEDITION 103 
slimy mass of matted branches now, covered with a wriggling, 
twisting host of serpent-stars; while from the crevices of its 
lobed roots scuttle numerous little crabs, and worms crawl 
from their refuge. Our collecting tubs are soon filled and the 
bottom covered with the litter of smashed coral heads from 
which we have gleaned a rich harvest. 
The boatmen with long clean strokes bend to their task, as 
we glide over the swell homeward bound across Carlisle Bay 
with its camouflaged ships and gleaming white sails of local 
eraft, along the shore of our island home and into the little cove 
just as a loud blast of the conch announces the welcome lunch 
awaiting us on shore. I know of no more delightful col- 
lecting than this. 
Among the smaller species of corals were Colpophyllia with 
large tubular calyces agglomerated together, their walls being 
eoherent throughout; Favia, small rounded heads with shallow 
polygonal calyces without evident eccenenchyma; several species 
of Porites and Siderastrea, and a Mussa. There were three 
species of Agaricia: the common Agaricia agaricites, A. fragilis, 
dredged at Station 71, depth 60 to 70 fathoms, and another spe- 
cies that will be described later. One specimen of A. fragilis is 
the finest that I have ever seen, being in the form of a large 
thin plate almost flat, fifteen inches wide and one foot high; 
the surface marked by rugose ridges or transverse corrugations 
which are wavy, often interrupted, and sometimes branched. 
Along the upper edges of these corrugations, close to the general 
surface of the corallum, the pocket-like corallites are seen in 
close set rows. From their centers radiate the delicate septa, 
which are continued downward over the rugosities and inter- 
vening ceenenchyma, forming fine lines or sharp ridges running 
vertically, and as nicely spaced as if ruled. These ridges are of 
two orders, higher and lower, alternating with each other. This 
extremely fragile specimen reached home somewhat damaged, 
but easily repaired, as the broken edges matched perfectly. 
When fresh the specimen was a pure light gray color. 
Another Agaricia, secured at Station 96 over what is known 
by the fishermen as ‘‘Shoal Bank’’ at a depth of about 30 fath- 
oms, is new to me, as I have never seen any description or figure 
at all like it. It grows in clumps resembling head lettuce, be-
