XXXVIII. — Remarks on the Guanaco of South 
America, 
By Thomas Stewart Traill, M.D. F.R.S.E. &e. 
{Read 8th February 182S.) 
Many authors have described four animals inhabiting 
South America, the Llama,* Vicuna, Paco, and Guanaco, 
as distinct species : but there appears so much confusion in 
their descriptions, that there is every reason to conclude 
they have mistaken the effects of domestication for specific 
differences. Cuvier has followed Pennant in considering 
the Llama as the domesticated Guanaco, and the Vicuna 
the tamed variety of the Paco. This point has probably 
been illustrated by the researches of the indefatigable 
Humboldt ; but never having had the good fortune to see 
the zoological portion of his splendid work, I am unable 
to state the opinion of that illustrious traveller. 
• This is the Glama of Shaw, and other writers, who appear not to have 
been aware of the force of the LI in Spanish. It has the sound of the Italian 
Gl in the word Jiglio. The n in Spanish, has the sound of Gn m the Italian 
word ignudo.
