3C DIVISION I. VEKTEEHAL ANIMALS. — CLASS I. MAMMALIA. 



Lciiiie, — GcofFnjy'.s Potto (Z. potto). It moves at night, is slow of g:iit, 

 and feeds on vegetables. 



Otolicnus — The Galagos. They have large, membranous ears, and 

 lonn', tufted tails. Several species, peculiar to Africa, ha^■e been ascer- 

 tained. The Great Galago ( G. crKtisicdudatiis) equals a rabbit iu size, 

 and the Senegal Galago ( (r. tSencr/idejist's) is about as large as a rat, while 

 another species — the O. d'uDKiltii — is consideralilj larger than the hrst. 

 Tiiey are very rapid in their movements when seeking tlieir food, as they 

 do l)v night, leaping on their hind limbs from bough to bough. It is said 

 that tliey make nests in the branches of trees, and cover a bed \vith grass 

 and leaves for their little ones. 



Taiisius — Tlie Mai mags. The INIalmags inliabit the ^lohiccas. f'niy 

 two species are known. They have long, naked tails, feed on lizards, live 

 in pairs, and have the same nocturnal hal)its as the foregoing. 



GiiEiPiOGALEUS — Ciieirogales. Tlu'cc species are ascertained, which re- 

 semble the Galagos in their j)roportions, and the ^Nlalmags in the arrange- 

 ment of their Kctli. Tlicy are confined to tlie Island of ^Madagascar. Of 

 their habits very little is known. They have a rouml head, short nuizzle, 

 and li2)S with whiskers. 



It is curious to observe the gradual departure or descent from the human- 

 like form, wliicli so strongly arrests our attention as we pass through tlie 

 several families of the (^uadrumana, from tlie Apes to the Lenuu-s. The 

 power, voluntarily, to imitate the actions of man, is confined wliolly to the 

 Simiadas and ceases witli tlie Ouistitis. The Lenuu's are active, but have 

 far less intelligence than the monkey-like animals, and no capacity for 

 mimicry. Yet all the branches of this great division present numerous 

 deeply interesting features ; and their habits, modes of life, and manifesta- 

 tions of intelligence open a wide field for agreeable study. 



OEDER m. CHEIROPTERA. 



The-word Cheiropier(( — a compound of two Greek words, meaning Itaml 

 and tciiir/ — lias reference to the peculiar formation of the wings of the sev- 

 eral families tliat compose this order, in which the hands and fingers, and a 

 membrane that unites the last, are so extended as to form wings, which 

 generally surpass iu size even those of birds. The Order is distributed into 

 several families and tribes, and these again into numerous Genera, which, 

 iu their turn, are resolved into Species, almost innumerable, differing in
