GLTPHOEHTNCHUS. 175 



short, the culmen and gonys are gently curved downwards and upwards, and both 

 maxilla and mandible expand laterally towards the tip and are rounded at their ends ; 

 the nostrils are completely overhung with a membrane, leaving the opening a narrow 

 curved slit lying along the lower edge of the nasal fossa. 



The range of the genus extends over the greater part of Tropical America, 0. cune- 

 atus being a denizen of the low-lying virgin forests.
