Brown, with a clear brown baud along middle of trunk and another 

 along lower part of belly; posterior canines strong; edge of jaw strongly 

 emarginate; posterior border of caudal flexuous. Cuba (Poey); not seen 

 by us. This species may be, as Poey suspects, simply the normal form of 

 Scarus acutus, the type of the latter having no canines. The coloration of 

 the two is the same. (yvaBog, jaw; oSov^ tooth.)
