Port Lockroy, Dorian Bay area. Base A. 
In this area the Gentoo penguins take the place of the Adelies hut 
for this major difference hird life is as varied as elsewhere though the 
number of individuals seems less than at Arthur Harbor. Three chinstraps 
were seen among the Gentoos here by Lt. Thomas. I do not recall seeing 
any Giant petrels here. Rookery space is more limited, resulting in fewer 
colonies, but those available are well populated, hear at hand to, but 
not on the Base A site are sizeable Gentoo colonies, and also at Damoy 
Point on the way to Dorian Bay is another large one. A colony of terns 
holds forth on a, rocky, steep-to headland near the entrance to this port, 
and a well populated shag colony occupies an island in Peltier Channel 
(Priest Td?) on the way to South Bay, Doumer Island where the Chilean 
Base "Yelcho" is located. Additional colonies of Gentoos occur down this 
way, also. Skuas, Wilson's storm petrels and sheath-bills were about 
too, and in the harbor. 
There was comparatively little vegetation to be seen, nothing at all 
to compare with the luxuriant vegetation that we were to see later in the 
Argentine - Berthelot Island area. From moss gathered here a few Col- 
lembola were berlesed. 
$ 9-63 The more meager dredge hauls here, over a muddy bottom, in general

character resemble those made at Arthur Harbor. Worm tubes were abundant; 
ophiurans (serpent of brittle stars) and ascidians of species other than 
those obtained at Port Arthur were washed from the mud. Additional spe¬ 
cimens of these species were secured by the same means on occasion of our
