with bands of small yellow spots on No. 537. It is probably the larve of the white butterfly with black markings which is numerous. Found a fairly large red-brown jumping spider which had just caught a fly (Synthesomyia nudicata); took it away from him. Saw one or two more flies of this species about. Small grayish white hermit crabs numerous. Collected a few. Found fig wasps in the ripe figs of the few large leaved Ficus trees. Small lizards numerous. Several banded snakes in crevices. Returned to ship at 11 A.M. and underway for Bacon Island which lies about 2 miles to the east by north. Roll 65:2. West face of Bacon I[sland], looking east. (11540) Landed at about 12:45, on the point, [illegible] west side which is the only piece of the face which is not precipitous. Even this rises 10 to 15 feet steeply from the water. Bacon I[sland] is about 80 or 90 yards long, N. and S. and less than 40 or 50 yards wide, tapering at both ends. It is composed of extremely rough and jagged limestone. The pilot book and chart give the height as 60 feet, but it is scarcely more than 45' or 50'. Between the knife edges on its sides are small pockets of dirt richly impregnated with bird guano. In these grow little patches of sesuvium (near the edge), Portulaca - both yellow and white blossoms (No. 539) a purple stem- med creeping herb resembling Portulaca but with thinner leaves; bunch grass; and a weed shrub (No. 538) which is the dominant plant. Plants and rocks are "whitewashed" with bird dung. Numerous nesting boobies and a few terns. Large number of banded black and cream water snakes of all sizes. Small lizards. Insects few as to species, but large number of individuals:- leafhoppers, small yellow flies, slightly larger black (Agromyzid?) flies, greenish crane- fly on Sesuvium, Portulaca and No. 538. These and in addition a Psyllid and a green leafhopper on bunch grass. Saw a Sarcophagid fly and a red coccinellid.
