living C. vinalensis. These shells seem to prefer 
the dark niches and there hang suspended by a slender 
thread varying from four to eight inches in length. 
Henderson found one and I, the other. We also crossed 
a small stream and made an exhaustive search along the 
cliffs bordering it, but found only a few bones. The 
catch listed on pages 12 - 13 was duplicated here, two 
additional species of TJrocoptids being added, which may 
be new. No Microceramus ms found. 
At the house Rodrigues ms catching day-flying 
moth which were attracted to a Mimosa tree that ms in 
full bloom. De la Torre told me that this ms a rare 
lepidoptera, and that some of the specimens would go 
to the Museum. 
A bath in the sulphur bath took out all the sore- 
ness from my body and left me in fit condition for the 
trip to Esperanza. The stage came by about 5:30 and 
we were soon on our my, passing through some of the 
most glorious scenery I have ever seen. The entire 
ridge of the Costanera de san Yicente is simply one 
picture after another, which, in the light of the 
setting sun, . ms little short of marvelous . We reached 
Esperanza at dark and thanks to the delay caused by 
De la Torre, who seems to think that the most important 
part of the expedition is to see that we are supplied 
with ice, we finally, as at San Vicente, went off and 
left him. 
May 11th:- 
Up early and off for the reef. These near this 
place consisted of mangrove-covered Keys with loose 
mud and calcarius algal fragments mixed with the 
tests and parts thereof of all sorts of animals. We 
made two hauls in about 5 to 8 feet of mter, and the 
stuff we brought up looks quite promising for mollusks • 
Examined quite a stretch of shallow mter and gathered 
all we could of marine invertebrate for the collection. r 
Among those collected were four actiniods of a goodly 
size and beautiful coloration. These specimens vary 
very much in c oloration. One has the stalk mshed with 
purple lake; the disc and basal half of the tentacles 
tarre verte (pi. 2 2/4), the lips bright purple lake, 
which pales and grades into green in the middle. Ancftier 
specimen has the stalk flesh colored, shading to silver 
gray at the edge. The tentacles are pale olive green 
at base, tipped with Hookers green (PI. 1 2/2). Another 
has a base like the above but the disc and tentacles 
are Hookers green, with a bright carmine tip at the 
extreme point. In still another, the carmine tip is 
missing. A small species has a flesh colored base 
with the center of the disc flesh-colored. The ten-
