Body and head compressed. Snout much produced, depressed, pointed. 
Forehead prominent, curving downward from crown to snout. First dorsal 
high, short, subtriangular. Second dorsal low, elongate, nearly as long as the 
head and snout together. Pectorals large, reaching the origins of the ventrals. 
Ventrals small. Noanal. Supracaudal low, about half as wide as the subcaudal, 
without spines on its upper edge; subeaudal 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; prenasal branch passing 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 and 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: the outer of small rounded tritors on the cutting edge, the 
second of small ones forward and large broad ones, forming a pavement, back- 
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 
series of tritors in the 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 numbers and shapes vary greatly with age. As with other 
chimaeroids the young have two rows of dorsal scales.
