Eyes hazel; the stomach had many portions of fish, some of considerable size ; upper part of the feet white, bill black or slate-coloured."-J. M. 741, female, Falklands. " Eyes brown ; stomach had fish."-J. M. In our opinion this species is quite distinct from S. demersus of the Cape, having a double band on the chest, as is well represented in Forster's figure. 5.

There is, however, less appearance of the white upper tail-coverts in the Falklands specimens. W h y Mr. Sharpe should have supposed that E. chrysolophus (Sclater et Abbott) of the Falklands was his E. saltator we cannot understand. Forster evidently had both the " Rock-hopper" and " Macaroni" Penguins under his eyes when he described his Apt. chrysocome **. Brandt first clearly separated the two species, which are quite distinct and easily recognized by the character which Brandt gives. The type specimen of E. diadematus, Gould, for which we have made every inquiry, is unfortunately no longer to be found. Mr. Gould has parted with it, he knows not whither. It was probably only an individual variety cf this species. 6. EUDYPTES CHRYSOCOME. Aptenodytes chrysocome,Forst.'S. Comm.Gott. iii. p. 135 (partim). Catarractes chrysocome, Brandt, Bull. Ac.
