112 ORDER II. QUADRUMANA. 



are nearly of equal length; the fingers armed with 

 sharp claws. A peculiarity found in this genus 

 alone is, that their canines are curiously indented, 

 and short, like the molars ; only two indented in- 

 cisors ahove, very wide asunder, and below six, cleft 

 with narrow pectinated grooves. They are arboreal, 

 living in the Indian Archipelago. Until lately, only 

 one species was known. 



G. Temminckii, Waterh. Calugo, or Olek. 

 Temminck's Flying Lemur, or Lemur Yolans of 

 Linn. Grey rust colour above, pale rufous beneath. 

 Found in the Moluccas, Penang, &c. And a second, 



G. PhilippmensiS) Waterh. Philippine Flying 

 Lemur. Brought from the Isle of Bohal. The 

 variegated specimens are merely the young of Co- 

 lugo, or of both. 



Fossil quadrumana were long undiscovered ; more 

 lately, however, in the lower tertiary (Eocene), re- 

 mains of a Baboon, or rather Macacus, have been 

 found in the Isle of Sheppy, London clay, and in 

 the newer pliocene deposits of Asia. Among the 

 Sewalek Hills, a Semnopithecus, allied to S. Entil- 

 lus, but larger; and bones of the face of another 

 species, still larger, were discovered. Cavern de- 

 posits have likewise produced fragments of quad- 

 rumana.
