Culpepper Island. 
Culpepper is located farther north than any other island in 
the group, and it is also one of the smaller of the islands. De¬ 
posits of basaltic lava, and tufa make up the island and form 
perpendicular cliffs along its sides. The cliffs descend directly 
into the sea and render landing impossible except at one place on 
the north side where they have become broken down and formed 
a large mass of talus. A gently rounded plateau covers the un- 
per part of the island and has an elevation of several hundred 
feet. This plateau is inaccessible but is heavily covered with 
vegetation, which appeared from the vessel to be composed 
mostly of Bursera trees and Croton bushes. In addition to the 
above, there are a considerable number of small bushes, very 
similar in size and appearance to Scalesia Snodgrassii, which oc¬ 
curs on Wenman Island about twenty miles to the southeast. 
Thickets of a species of low Opuntia also occur here. On the 
talus slope, near the landing place on the north side, a few 
bushes, of Croton Scouleri var. brevifolius, and Telanthera 
Helleri occur. Bright red patches of vegetation were seen at 
various places along the sides of the cliffs a short distance above 
the water. These are probably composed of Sesuvium Edmon- 
stonei as it forms similar patches elsewhere. One member of the 
party reported having seen the remains of sedges, the first time 
that these plants have been reported from this island. 
Daphne Island. 
Daphne Island is a small tufa crater, about half a mile in di¬ 
ameter, and 200 ft. high, which is located five miles north of In¬ 
defatigable Island. The sides of the island are steep, and with 
the exception of a few small trees of Bursera graveolens, there is 
but very little vegetation on them. The only plants collected 
here were: Abutilon crispum, Euphorbia amplexicaule, and Tri- 
bulus cistoides, all of which were taken by Mr. F. X. Williams 
from the inside of the crater. 
Duncan Island. 
Duncan is a small island, about three miles in diameter, which 
lies between Albemarle and Indefatigable Islands. The shores 
are steep and are made up of tall cliffs on all sides but the north
