 distinguished by the presence of a long white spot on the chin. 



The two remaining species are Baird's tapir (T. bairdi), ranging from Mexico 

 to Panama, and Dow's tapir (T. doivi), restricted to Guatemala, Nicaragua, and 

 Costa Rica, which constitute a second group of the genus distinguished by the 

 characters of the skull. In all the three species of the first group, as seen in the 

 figure of the skeleton given on p. 454, the nasal cavity is perfectly open in advance 

 of the roofing bones of the skull ; but in those of the second group this cavity is

 the figure of the skull of an extinct rhinoceros. 



The following notes on the habits of the American tapirs refer

 themselves exclusively to the thickest pai'ts of the forests, carefully avoiding all 

 open spaces, and forming regular pathways along which they travel in search of

 and darkest portions of the forest tapirs may be encountered abroad during the
