116 IOWA STUDIES IN NATURAL HISTORY 
tubular hydrothece abruptly bent in the middle, the lower half 
being immersed in the perisiphonie stem. The type specimen is 
from near Havana. Perisphonia chazalier was found at Station 
11, depth 67 to 70 fathoms. Several species of Lafoea were se- 
cured, and as usual they were mostly parasitic on other hy- 
droids. Campanularia marginata, a very common West Indian 
form with unusually large, almost sessile hydrothece, was se- 
cured. 
Of the hydrocorallines, Millepora alcicornis was as usual the 
commonest and most conspicuous. Its protean forms occur on 
most of the reefs throughout the West Indian region. We did 
not succeed in seeing the living zooids. Many delicate and 
beautiful species of deep water hydrocorallines were brought 
up in the dredge; but these have not yet been studied sufficient- 
ly for their identification. 
Of sponges there were no end, but the writer has not sufficient 
temerity to attempt even an approximate identification in this 
group. One of the largest was abundant just outside of the 
reefs off Hastings. It was’somewhat the shape of a cocked hat 
and was often three feet or more in length. The illustration 
shows the shape better than any description. The specimen 
photographed has a gorgonian growing on it. Another strange 
sponge is colored black and is about six feet long and four 
inches in diameter being almost perfectly round in section. 
Many ecaleareous and some silicious species were found in the 
dredged material. Their sharp needle-like spicules were an 
almost constant nuisance and kept our hands sore a good deal of 
the time. 
Entomological notes. Mr. Dayton Stoner the entomologist of 
our party, has very kindly allowed me to use the notes that he 
has drawn up concerning his experiences while collecting, and 
some of the species which he secured. The facts are his, but 
the language is mainly the writer’s. 
The island of Barbados, being densely populated and having 
practically its whole area under cultivation, is not a particularly 
favorable place for collecting insects. In general it may be said 
that the insect fauna shows some affinities with that of South 
America as well as of North America. A few of our familiar 
species are found there as well as a number of indigenous forms.
