 According to Gray, the British Museum examples are from the 

 Auckland and Campbell's Islands. Judging from Mr. Peale's 

 account, the Aucklands are a headquarters of the species. 



The Aptenodytes Jiavilarvata of Peale was long ago referred 

 by Cassin to its proper place.

06s. This species is at once distinguished among the crested 

 ones by the shortness of the tail, which in size and shape rather 

 recalls S. demersus. This member is under three inches long, 

 rounded, of fourteen narrow stifflsh graduated rectrices. From 

 either chnjsocome or chrysolopha it is also known by its inferior 

 size; and from chrysocome, its nearest ally, by the quite blue 

 upper parts, as in chrijsolojiha, the color of the back of chnj- 

 socome being quite dark. 



This appears to have been the earliest described of the crested 

 species, and its synonymy is in such a state of confusion with 

 that of the following, that probably it is now impossible to com- 

 pletely unravel it. Such points as we have been able to determine 

 with some confidence, and which probably are correct, are given 

 in connection with chrysocome.

 white to the bill, but the gular dark beginning to show ; upper-
