most common form, its trivial name being derived from its 

 peculiar cry. 



Three species of the genus Ckrysothrix are known. The 

 TEE Tee (Chrysothrix sciureus Wagner) is a familiar ex- 

 ample, so named from its two-syllabled cry. Its generic 

 name refers to its beautiful fur, and its specific to its re- 

 semblance to the squirrels. 



The term Callithrix has a similar meaning to the pre- 

 ceding generic name. Eleven species of this genus are 

 known. They are also called TEE Tee, having a like cry. 

 By some they are called Orubas.su, from a local, native 

 word. 



There are sixteen species of very small monkeys, called 

 respectively Marmosett, Marakina, Pinche, Midas, 

 and Tamarin, all probably from native designations. 

 There are seven genera which embrace the above species, 

 as follows : Hapale, Jacchus, Cebuella, Mico, Lcontopithccus , 

 (Edipits, Midas, Cenocebus. 



The Marakina (Leontopithecus rosalia Gray) is a more 

 common form, called LlON Monkey from its singular 

 resemblance to that beast. The Makmosetts are interest- 

 ing pets, and appear to be the most harmless and timid of 

 all mammals. 



GROUP 7. — The Lemurs, family Lemur i da, are nota- 

 ble for being native to one comparatively small area, 

 that of the island of Madagascar. There are forty-one 

 species embraced in thirteen genera. The largest and 

 most interesting form is the INDRIS (Indris brevicaudatits). 

 The creature has a most remarkable arrangement of black 

 and white fur; its tail is too short to be observed, differing 

 greatly in this respect from the very beautiful pompon-like 

 appendages of the nearly allied DlADEM ^Lemurs, five 

 specimens of which are grouped near the former. 



The family of LEMURS proper embraces the genera 

 Indris, Propit heats, Avahis, Lemur, Hapalemur, Lepilemur, 

 Chirogaleus, Galago, Lor is, Nyeticebus, and I 3 erodictus. 

 The smallest of the group is the Demidokf Galago
