will be seen from the accompanying figures, quitedifferent in plumage. Of Sj)heniscus demersus we have had many examples living in the Zoological Societysgardens, and the species is now well known to us. When adult they never fail to arriveat the plumage shown in Plate XXVII. The present species is of about the same size asSpheniscus demersus, and it might be perhaps not always easy to distinguish the youngbirds, such as is shown in Plate XXVIII. fig. 2. But in the adult of Spheniscus magel- 126 THE VOYAGE OF H.M.S. CHALLENGER. lanicus (PL XXVIII. fig. 1) the well-marked double black band on the breast renders thespecies at once recognisable. Another quite distinct species that Dr Coues has united to Spheniscus demersus isSpheniscus humboldti, Meyen, of the coasts of Chili and Peru. This specimen has onlyone black band like Spheniscus demersus; but this band is much broader, while thewhite frontal band is much narrower. It is also considerably smaller in dimensions. r ■ ■ / YU/ly

Spheniscus humboldti. (From Proc. Zool. Soc, 1879, p. 8.) Mr Murray sends me the following notes on Spheniscus magellanicus :— We frequently saw these birds in the eastern parts of the Straits of Magellan, butalways in the water. At the Falklands we found several rookeries. These birds burrowinto both sandy and peaty banks. Sam, our Newfoundland dog, dug out some ofthese nests fully 8 feet into the sand hills. In their stomachs were fish-bones, cuttlefish beaks, and pebbles. It is quite astonish-ing the number and size of the stones, shells, and pebbles which were noticed lyingabout the mouth of the burrows. REPORT ON THE BIRDS—STEGANOPODES AND IMPENNES. 127 The sealers told me that these birds when they come up from the sea vomit up thesestones at the mouths of their burrows, and when they go to sea again they take in thevery same stones as ballast. The sealers say the fur-seals take in ballast in the sameway as the Penguins. 5. Eudyptes chrysolophus, Brandt (PI. XXIX.). Aptenody
