Type. Detached tooth. 
A species attaining a maximum length of not less than 2-8 metres ; 
snout rounded and obtuse ; anal fin smaller than the dorsal, probably 
not at all opposite the latter. Vertebral column as in the existing 
Bubgenus Neptanchus (according to Hasse). Principal cone in the 
lateral teeth relatively large and broad, without anterior denticles, 
and followed by not more than three or four secondary cones. 
A nearly complete fish in the Munich Museum is made known by 
Beyrich and Frischmann and by Wagner ; but the supposed young 
individuals referred to by the latter do not belong to the family of 
Notidanidm (see Pristiurus).
