We visited Elephant Island on March 28th, and effected landings at Cape Lookout and on a narrow beach at the western end of the northern coast. Animal life is scarce, and plants are confined to a lichen, which grows on some of the rocks on the sides facing north, and a species of moss. The bird life consists of Gentoo, Ringed and Rockhopper penguins, the latter being very scarce; seabirds, including Cape pigeons, Skua gulls, Dominican gulls, Blue-eyed shags (all of them plentiful), and Mollymauks and Giant petrels (more rare). The Paddy, or Sheathbill (_Chionis alba_), is plentiful. The Ringed penguins made their rookeries on steep rock-faces close to the sea, and spent many patient hours in climbing up and down from their positions, hopping carefully from ledge to ledge. The Gentoos selected easier slopes. Rarely a Gentoo was found in a Ringed rookery, but Ringed were found fairly frequently among the Gentoos. The Paddies haunted the rookeries, their food being obtained largely from the excreta of penguins, from which they pick small round worms or nematodes, with which the penguins are infested. The stomach and intestines of the Paddies themselves are wonderfully free from parasites. They eat readily of any offal which may be lying about. Those which remained during the winter were very thin, due to the departure of the majority of penguins. Numerous seals and sea-elephants were lying on the beaches. On the rocks are dark-shelled limpets (_Patella polaris_), which never come above low-water mark; no doubt they would freeze to death in the colder air. We returned to South Georgia on April 6th, and left for Tristan da Cunha on May 9th. During the voyage we saw Wandering Albatross, two Sooty Albatross (_P. palpebrata_ and _P. fusca_), mollymauks, Silver-Grey petrels (_Priocella glacialoides_), Wilson petrels, Giant petrels, Diving petrels, several varieties of prions, Cape hens, Cape pigeons, Terns, Skua gulls and Shearwaters. As we neared Tristan da Cunha we lost _Phoebetria palpebrata_, and the only kind of Sooty Albatross seen was _P. fusca_. The islands of the Tristan da Cunha group are so close together that the animal life is similar to them all. The naturalist found eggs of the following: The yellow billed mollymauk (_Thalassogeron chlororynchus_), greater Shearwater (_Puffinus gravis_), Rockhopper Penguin (_Eudyptes chrysocome_) and _Catharacta antarctica_. The evidence of the islanders regarding the bird life of the islands is as follows (birds are recognized by general description and plates): Wandering Albatross used to breed on Tristan, but now only found rarely on Inaccessible Island. Sooty Albatross (_P. fusca_) nests in August. Young birds leave the nest in April (the young of _P. palpebrata_ were hatched on January 15th at South Georgia). Yellow-nosed mollymauks (_T. chlororynchus_) nest in August. Young birds leave the nest in April (the young of _T. chrysostoma_ were hatched on January 1st in South Georgia).
