from that of r.it'mi-pliclm. * * * The skull differs from that of Epi- 

 r/>/7.vby the wider interorbital area, the parallelism and continuation 

 of the lateral crests forward to the middle of the orbits inclosing an elon- 

 gated parallelogram, the surface of which, especially between the orbits. 

 is more uniform ; the absence of a frontal crest, the simple curvature or 

 straight ness of the naso-voiuerine ridge and absence of the angle at the 

 suture between the nasals and voiiicr." (Gill.) The species of this 

 group have the anal III, 11, er III, 12. They reach a very large size, 

 and are abundant in the tropical seas, (-psi-, thrice; r/x)-:?, a keel, in 

 allusion to the piesence of the three parallel elevated keels on the top 

 of the cranium, which distinguishes this genus from Epinephehis.)
