lower incisors inflicts ugly wounds. At times a Jlama or 
vicunia becomes actually insane, and seeks to destroy every 
living creature within its reach. Regardless of punishment, 
such creatures attack their keepers and their herd-mates, 
spit upon visitors, and rage up and down their corrals in 
most absurd fashion. Occasionally such individuals require 
to be completely isolated. 
The Llama, (Lama glama), is the largest and strongest 
member of the group. Its body is covered with a thick 
mass of long, wavy hair of fine texture, which may be either 
brown, white, white and brown, or almost black. The head 
and legs are short-haired like those of the guanaco. From 
time immemorial, this animal has been used as a beast of 
burden, and in the Andes has played an important part in 
the mineral industry by carrying silver ore and bullion from 
the mines. 
The Alpaca, (Lama pacos), is bred for its wool. It is 
smaller than the llama, but more abundantly haired on the 
legs, neck and head. Its fleece is long, and lies in stringy 
tufts. Usually its color is dark brown or black, but oe- 
easionally a white Alpaca is seen. A white specimen in the 
Zoological Park collection has blue eyes. 
The Guanaco, (Lama guanacus), is one of the most inter- 
esting and valuable wild animals now found in Patagonia. 
Unfortunately, it is so stupid and incapable that it is easily 
killed. The natives of Terra del Fuego, themselves almost 
the lowest and most ignorant of men, slaughter Guanacos 
for food by surrounding groups of them and clubbing them 
to death. 
In size the Guanaco is between the llama and vicunia, 
and its shoulder height is about 4 feet. Its hair is thick and 
woolly, of a pale reddish color, and there are naked patches 
on the legs. This species is found on the Andes, from Ecua- 
dor to Terra del Fuego, and appears to be most abundant in 
Patagonia. 
The Vicunia, (Lama vicunia), is the only member of the 
cameloid group which is not clothed with a mass of long 
hair. It is the smallest member of the group, comparatively 
short-haired, its color is a uniform light brown, its head is 
small, and there are no callosities on the hind legs. The 
Vicunia is found from southern Ecuador, through Peru to 
central Bolivia.
