Body :vn<l hcud coinpirssod. Snout much produced, depressed, pointed. 

 l'"oreliead pi'onunent, curving downward from crown to snout. First dorsal 

 high, short, subtrianguhu'. Secoml dorsal low, eloiitialc, neai'ly as Vm^ as the 

 head and snout together. Pectorals large, reaching the origins of the ventrals. 

 X'entrals small. No anal. Supracaudal low, about half as wide as the suhcaufial, 

 without spines on its upper edge; suhcaudal much wider and longer, origin near 

 a vertical from the end of the second dorsal. Lateral line nearly straight along 

 the middle of its length: i)renasal branch parsing from the nasal outward in a 

 broad curve to the side of the .snout, between the suborbital and the nasal, where 

 it continues forward and curves inward to the subrostral; jugular section meet- 

 ing the orbital behind the junction of the latter with the suborbital aiul the 

 angular. Each vomerine tooth with from seven to nine tritors (rods) on the 

 cutting edge. Palatine teeth with three more or less complete longitudinal 

 series of tritors: th" outer of small rounded tritors on the cutting edge, the 

 second of small ones forward and lai'ge broad ones, forming a pavement, ijack- 

 ward, the third irregular, composed of small and short tritors. The mandibular 

 teeth have a series of rods on the cutting edge in the forward half, and two 

 ssriesof tritors in thg posterior half, the inner being continuous with the forward 

 series and composed of broad pavement-like tritors. The very young have no 

 tritors and the numl)ers and shapes vary greatly with age. As with other 

 chimaeroids the young have two rows of dorsal scales.
