private citizens aided the enterprise in every 
possible way. 
At Barbados dredging was accomplished at 
about one hundred stations, working down to 
over 150 fathoms. This was rendered possible 
by the use of a fully equipped 27-foot launch 
provided by Mr. John B. Henderson, of Wash- 
ington, who accompanied the expedition and 
who will report on the collections of Mollusca 
of which many new or rare forms were taken. 
Practically all species taken with the dredge 
or tangles will provide new locality records 
extending the known geographical range. The 
fauna, while not so rich as that of the western 
end of the Antillean chain, or the continental 
shelf off the Florida Keys, is of remarkable 
interest from a distributional standpoint, 
while a number of new forms will interest the 
systematist. The apparent scarcity of certain 
groups abundant in the western parts of the 
West Indies, such as the Asteroidea, was 
something of a surprise. As is usually the 
case in a region of growing corals the cclen- 
terate fauna was most conspicuous, but there 
seemed to be a remarkable scarcity of meduse. 
Indeed the pelagic fauna was rather poor. 
Shallow water forms, on the contrary, were 
remarkably abundant and interesting, furnish- 
ing ample material for laboratory work and 
study of forms in situ. Some probably new 
forms of actinians and corals were secured. 
Balanoglossus was found in the sand near our 
laboratory on Pelecan Island. 
By employing a native diver many species 
were secured at depths from three to nine 
fathoms. Some remarkably fine corals and 
aleyonarians were thus obtained. The use of 
fish-pots and native fishermen resulted in a 
fairly complete set of reef fishes which would 
not otherwise have been secured. Very few 
deep-water fishes were taken. 
Many gorgeously colored comatulics were 
dredged, but the pentacrinoids were repre- 
sented by but a single Rhizocrinus. The ser- 
pent stars were, as usual, yery abundant and a 
number of simple-armed basket-fish were 
found. Crustacea were, of course, particularly 
numerous, perhaps the most interesting being 
small macrourans secured by breaking up old 
coral heads.

At Antigua the party was given quarters at 
the old dock-yard at English Harbor, a for- 
midable naval base in Nelson’s time. Here 
the conditions were entirely different from 
those at Barbados. The trade-winds were so 
strong and constant during our stay that little 
dredging could be accomplished, and the entire 
time was devoted to shallow-water forms in 
English Harbor, Falmouth Harbor and Wil- 
loughby Bay. These waters were over mud 
bottoms; the shores, however, being varied in 
the form of mud flats, mangrove swamps, sand 
beaches and rocky shores. Here were found a 
veritable wealth and variety of aquatic forms, 
a great majority being different from those 
secured at Barbados. 
Tube-dwelling worms, some of great size and 
beauty, were perhaps the most striking fea- 
ture; tunicates and holothurians coming next 
in point of abundance both in individuals and 
species. Among the Mollusca, a great quan- 
tity of beautiful Murices were collected off the 
sea wall, where they seemed to be devouring 
the soft parts of a bivalve (Perna) that was 
attached in great quantities near high-water 
mark. <A very large Chetopod, called locally 
“sea scorpion,” was found to bore through a 
heavy Livona shell, making a hole as smooth 
as a drill. 
Large and wonderfully beautiful anemones 
of several species were abundant, particularly 
in Falmouth Harbor, as well as the finest 
colonies of Pennaria that Ihave ever seen. 
‘The Echinoidea were well represented, mostly 
by well-known forms. 
One small spatongoid was found to live 
buried from six to twelve inches under the 
sand. Among the Crustacea, a very large 
land-crab, with orange brown carapace and 
purple and white chelx, was perhaps the most 
striking form. 
At both Barbados and Antigua extensive 
collections were made in the field of geology 
by Professor A. O. Thomas. Mr. Henderson 
made a practically complete collection of land 
mollusks, while Mr. and Mrs. Dayton Stoner 
did faithful and successful work in the ento- 
mologiecal field, in which they were very mate- 
rially: aided by both the local and imperial 
departments of agriculture. The field of
