for Ihem to burrow. They get their name from the noise they make 

 which sounds like the braying of a Jackass. There may be Jackass 

 Penguins at other places, such as South Georgia, but I did not see 

 them and do not think there are."

One skin and two eggs from Kerguelen and one egg from South 

 Georgia. There are also two mounted specimens ('746a and b) from 

 Kerguelen in the museum collection that were presented by Mr. 

 Richard H. Chapell in 1870. 



The synonymy of this and the following species seems to be very 

 badly mixed and I can heartily endorse the remark of Mr. Sharpe, 

 *' Apparently we have here as complete a tangle as can be found in 

 the annals of ornithology, and that is saying much ! " (1. c. p. 159)i 



All three of our specimens agree perfectly with Brandt's original 

 description, so far as it goes, so that I unhesitatingly adopt his 

 original name. Forster's description* would seem to show that he 

 had both this species and chrysoco7ne in view when he described the 

 latter species. 



Some of Prof. Hyatt'sf differences do not seem to hold good, 

 especially the number of scutellse on the first joint of the toes, as these 

 apparently vary in the same species. Neither can I satisfactorily 

 distinguish between our two species by the under side of the wing, 

 they being much alike in this respect, and I fancy that individuals of 

 the same species vary more or less in this respect, so that the only 

 characters that he gives, that are left, are the distribution of the dark 

 color on the throat and the form of the crest, but, as he does not give 

 the color of the latter, it is difficult to determine his species, but I 

 fancy they are all the same or at most only sub-species due to
