Genus XYRICHTHYS Cuvier. Razor-fishes.

 of their extremely compressed oblong bodies, the upper and anterior edges being 

 sharp. Body deepest immediately behind head, whence it tapers gradually to 

 the rather broad caudal peduncle; head very short, deeper than long; profile from 

 eye to mouth nearly vertical; eyes small, near top of head; mouth small, low, 

 terminal, with 2 anterior canines in each jaw; scales rather large, head practically 

 naked; lateral line high, interrupted posteriorly and beginning again on a lower 

 row of scales; dorsal fin beginning close behind eye, long, low, and continuous, 

 with 9 spines. Several American species. {Xyrichthys, razor-fish.)
