Teeth.— I. , C. , P. , M. = 34. Some au- 



3—3 1—1 2—2 3—3 



thors give the formula in a slightly different manner, as the 



2—2 0—0 _ 2—2 

 teeth seem to be rather obscure : — I. , C. , P. - — -, 



M. = 34. The lower incisors are set pointing forwards, and 



4 — 4 

 are deeply notched on their crowns like the teeth of a comb. 

 Habitat. — Java, Borneo, Sumatra.

Limbs— Feet with five fingers — Fore-feet with toes long, the 

 middle toe long and slender — Thumb of hind-feet with flat and 

 broad nail. 



Tail. — Long, and heavily furred. 



The family in which this animal (the Aye Aye) ought to be 

 placed is very doubtful, as is even the order to which it really 

 belongs. 



Family.— Cheir6ptera. 



The bones of the fore-limbs, and especially those of the fingers, 

 much elongated, and sustaining a membrane of large dimensions, 

 by means of which the animals fly in the air. The thumb-joint is 



not attached to the web, but is left free. It is furnished with a 

 nail. The hinder-feet are small, and the toes furnished with 

 sharp claws. 



Teeth.- 



Genus. — Vampirus.

cially those of the lower jaw, and nearly contiguous at their 

 bases — Canines large.

 horizontally, and the other being erect — The ears are moderate, 

 and the tragus is small and elongated.

 together with Plecotus.

By some zoologists this genus is separated into four, namely : — 

 Leo, Tigris, Leopardus, and Felis, but apparently on insufficient 

 grounds.
