CYSTOPHORIN#, MIROUNGA, 545 
Lower California and Patagonia. They are enormous creatures 
rivaling the Walrus in bulk and stated to reach twenty-five to thirty 
feet in length. This great size, however, is found only in the animal 
from Heard’s Island near the Patagonian coast. Their circum- 
ference is said to reach eighteen feet. Probably the individual varia- 
tion among them is very great, and the females are much smaller 
than the males. The young and the females have no proboscis, 
but the males have one that in moments of excitement can be elongated 
to the extent of twenty inches or more. Formerly it is probable 
that these animals were quite numerous in the localities they fre- 
quented, but incessant slaughter has so reduced their numbers that 
the northern species is even now practically extinct, and the southern 
one has disappeared from some of its customary haunts. It is to 
be much regretted that man’s insatiable greed is gradually extermi- 
nating the more valuable animals from the earth.
