88 IOWA STUDIES IN NATURAL HISTORY 
inating colors of these were red and yellow, which also charac- 
terized the comatulids as well. I find the following colorations 
of free crinoids mentioned in my notes: ‘‘yellow and white; 
yellow and red; purple and white; black arms, with yellowish 
pinnules; rich deep vermillion, with bright yellow pinnules; 
lemon yellow, with black upper surface to the arms; grayish in 
color; violet in tinge; a crimson crinoid arm; black, with green- 
ish yellow arms; magenta, with dark yellowish arms; one speci- 
men very dark gray, almost black, with whitish cirri.’’ 
It is almost certain that a thorough exploration with dredge 
and tangles off the north and east coast of Barbados would yield 
a rich harvest of crinoids, both stalked and free. Dr. Austin 
Clark tells me that stalked forms can be collected by diving, off 
the coast near Bathsheba. The surf was so high during our 
entire stay that we could not trust Mr. Henderson’s twenty-seven 
foot launch in these dangerous waters. During late summer 
and early autumn, the sea is often calm for a week or more at a 
time, and it would then be possible to work there with a launch. 
Otherwise, a boat of considerable size would be required. I 
often longed for the good old ‘‘Emily E. Johnson’’ which we 
used so successfully on the Bahama expedition. She could do 
good work off the windward coast of Barbados. 
At Station 11, depth 67 to 70 fathoms, we secured twenty- 
four fine comatulids at a single haul. Several times we brought 
up what we took to be arms of Pentacrinus, but of this we 
could not be sure. Perhaps they will be identified when the col- 
lection is reported on. 
Mollusca.—The following notes have been kindly prepared for 
me by Mr. Henderson: 
The conchologists of our party were disappointed in Barbados 
with the returns from the beaches and other water-margin 
stations. This is not an unusual experience of northern visi- 
tors to tropical places, and is because of the barriers of coral 
reefs on the usual rough rocky bottom just off shore. As a 
matter of fact the littoral molluscan fauna of Barbados is poor, 
both in species and in number of individuals. This is owing to 
lack of proper stations; the shores are very much exposed to 
rough seas and strong currents and there are no sheltered wa- 
ters. On the windward side of the island, where a heavy surf
