persistent pulps and enamel in front only, as we have seen 
in the rodents. The toes have claws, except the great ones, 
which have a flat nail ; the digits are remarkably long and 
slender, especially the middle and third of the fore-arms. 
They are about the size of acat. The general color is dark 
’ brown, the long, loose, outer fur having a woolly under- 
coat. They feed upon the succulent juices of sugar-cane, 
also insects and grubs obtained from trees with their pow- 
erful teeth. They are truly nocturnal. Their nests are 
formed of balls of leaves lodged in the forks of large trees. 
Lemur (Lemuride).—The ring-tailed lemur (Lemur 
catta) is one of the most striking of the family, and is of 
a beautiful gray color, its tail marked with alternate rings 
of black and white, the face and inner surface of the 
ears white, and the top of the head dark. It is the only 
ground member of 
the family, living 
among the rocks 
and bushes, walk- 
ing on all-fours. 
The upper canine 
teeth are extreme- 
ly large, the low- 
er canine extend- 
ing out horizon-

of the mother, later clinging to her long hair. They utter 
loud cries, and feed upon eggs, young birds, insects, fruits, 
buds, or flowers (Fig. 376). The Profithecus is a com- 
mon form in Madagascar ; the Indris is the largest of the 
group. Allied is the lori (Fig. 377).
