Troglodytes
in ornithology, the wren; a genus of Troglodytidæ or Troglodytinæ, from the Neotropical, Nearctic and Palæarctic regions. Bill moderate, compressed, slightly curved, without notch, pointed; nostrils basal, oval, partly covered by a membrane; wings very short, concave, rounded; tail generally short; feet strong, middle toe united at the base to outer, but not to middle toe; tarsus rather long; claws long, stou stout, and carved.
In zoölogy a genus of Simiinæ. Head not produced vertically; arms not reaching more than half down the shin; ribs 13 pairs; os inter-medium absent from the carpus; no ischiatic callosities; hair black, dun, or gray. The genus is confined to the west African sub-region, ranging from the coast about 12° N. and S. of the equator, from the Gambia to Benguela, and as far inland as the great equatorial forests extend. The number of species is not accurately determined; TROGLODYTIDE three, however, are well known, and have been carefully described: T. gorilla, the gorilla; T. niger, the common, and T. calvus, the bald chimpanzee. There are probably other species, since Livingstone met with what he supposed to be a new species in the forest region W. of the Nile, and another has been described by Gratiolet and Alix.
