PROSIMIJE (LEMURS). 



331 



The second toe of the foot alone forms an exception, being armed 

 with a long claw. There may, however, be a claw on the middle 

 toe. The tail presents great variations in size and development, but 

 can never be used as a prehensile tail. The Prosimice inhabit ex- 

 clusively the hot regions of the Old World, principally Madagascar, 

 Africa, and South Asia. They are almost all nocturnal in their 

 habits, climb with great skill, but slowly and lazily, and feed en 

 Insects and small Vertebrates. 



Fam. Galeopithecidae = Dermoptera. With closely-furred patagium, which 

 they use as a parachute in jumping. 

 Lower incisors pectinated and inclined 

 forwards. They are most nearly allied 

 to the Makis ; they are nocturnal in 

 their habits, and lire partly on fruit and 

 partly on Insects. During the day they 

 sleep io. their . hiding-places, suspended 

 like Bats. Galeopithecus volans L., the 

 flying M!aki, Island of Sunda. 



Fam. ChiromyidsB. With rodent-like 

 dentition, and with claw-like nails on 

 the Angers and toes. The large opposable 

 great toe of the hind foot alone has a 

 flat nail. In the prasmaxillee and in the 

 lower juw there are two large rootless 

 incisors, which project obliquely for- 

 wards, and, unlike those of Eodents, are 

 covered with enamel on both sides.

 With tMck head, large ears and eyes, 

 short snout, much elonged proximal tar- 

 sal hones (calcaneum and naviculare), 

 and lonjj tail. The middle toe as well 

 as the second may be armed with a 



claw (Tiirsius}. In their appearance they resemble the Hazel-mice (Myoxus 

 avellanarhis], in their movements the Squirrels. Tarsius spectrum Geoffr., 

 (Gespenutmaki). 



Fain. 'Lemuridae. The lower incisors directed horizontally forwards. Only 

 the soccad hind toe has a claw-like nail. Stenops gracilis V.d. Hoev., the
