eastern Asia. Their bodies are protected by overlapping epi- 

 dermal scales which can be erected. Like the armadillo, they 



can roll themselves into a ball. 

 The tongue is long and ex- 

 tensile; it is used to capture 

 white ants or termites, upon 

 which it feeds. Pangolins walk 

 on the dorsal surface of the 

 claws of the fore feet and on 

 the soles of the hind feet. They 

 are terrestrial, burrowing, or 

 arboreal, and from one to five 

 feet in length. 



Order Primates. LEMURS, 

 MONKEYS, APES, MAN. There 

 are two suborders and eight 

 families of living primates; the 

 lemurs (LEMURIM), aye-ayes (CHIROMYID.E), tarsiers (TAR- 

 SLED.^), marmosets (HAPALID^E), South American monkeys 

 (CEBID^E), Old- World monkeys (CERCOPITHECID^E), anthropoid 

 apes (SIMIID.E), and mankind (HOMINID^:). It is customary 

 to place these animals at the end of the vertebrate series, but 

 they excel the UNGULATA and CETACEA chiefly in the large size 

 of the brain, and retain many primitive characters, some of 

 which are found elsewhere only among the lowest placental mam- 

 mals, the INSECTIVORA. 



The primates inhabit chiefly the warm parts of the world. 

 They are mostly arboreal in habit, and are able to climb about 

 among the trees because the great toe and thumb are oppos- 

 able to the other digits, adapting the hands and feet for grasping. 

 A few primates lead a solitary life, but most of them go about in 

 companies. Fruits, seeds, insects, eggs, and birds are the princi- 

 pal articles of food. One young is usually produced at a birth; 

 it is cared for with great solicitude. 



The lemurs (LEMURID.E) are quadrupeds and small or moderate
