2 IS LECTURE VI. 



The other genus, or Phaeton, with which Lin- 

 nseus once associated the Penguins, merely on ac- 

 count of the form of the beak, is called the Tropic- 

 Bird. The principal species is the Phaeton aethe- 

 reus of Linnaeus, and is so named from the vast 

 height to which it soars. It is about the size 

 of a large Duck, but more slender in proportion, 

 of a silvery white colour, with numerous trans- 

 verse blackish bars or streaks, and has the middle 

 tail-feathers extremely slender, and of a vast 

 length in comparison with the rest. It is rarely 

 seen beyond the limits of the Tropical regions. 

 Another species is of a pale rose colour. 



After these examples of the tribe Anseres or 

 web-footed swimming-birds, it would be unneces- 

 sary to dwell on the less conspicuous genera of 

 the order. I shall therefore request your attention 

 in my next Lecture, to the animals distinguished 

 by the title of Amphibia,
