LXXXIX, 156, Aug., 1819. 
Type: Troglodytes niger Geoffroy (=Simia troglodytes Linnzeus), from the coast of 
Angola, Africa. This species has formed the basis for nine distinct generic 
names; a distinction unequaled by any other mammal. (See p. 785.) 
Name preoccupied by Troglodytes Vieillot, 1806, a genus of Birds. Replaced by 
Pseudanthropos Reichenbach, 1860, and by Pongo Haeckel, 1866 ( preoccupied ). 
See Pan Oken, 1816; Mimetes Leach, 1820 (preoccupied); Theranthropus Brookes, 
1828; Anthropopithecus Blainville, 1838; Hylanthropus Gloger, 1841; and Engeco 
Haeckel, 1866. Pan is apparently the earliest available name for the genus. 
Troglodytes: tpw@yAodurns, cave dweller (lit., one who creeps into holes).
