The type species of Megistopus, attaining a length of about 0 > 
and of slender proportions. Length of head with opercular 
apparatus equalling twice the maximum depth of the trunk, an 
slightly exceeding one third of its length from the pectoral arch to 
the base of the caudal fin. Pectoral fins apparently as in the tjp’ 
species ; but the pelvic fins more remote, with about 13 ra y®’ 0 
which the longest scarcely roaches beyond the origin of the ana n 
when adpressed to the trunk.

Head relatively large and jaws apparently toothless. Veiteb 
between 40 and 50 in number, about half being caudal. 1‘ * rl 
mostly divided as well as articulated distally. Pectoral fins arn 
near the ventral border, delicate but larger than the pelvic 
which comprise about 8 rays and are supported by much exp® 111 ^ 
pelvic bones ; dorsal fin arising opposite or somewhat in advance 
the pelvic pair, and occupying less than half the back; cauda 
slightly forked. Tho dorsal region protected with a covering ^ 
small, thin, rounded or polygonal dormal scutes, each beann„ 
median tubercle. 
One of the original specimens of the type species in the A cade 7 
of Miinster (noticed by W. von der Marck, Palseontogr. vol. ■ ‘ 
1>. 248) clearly exhibits the upper jaw. The slender toot ^ 
premaxilla is shown to form the upper border of the mo 
excluding the maxilla, which has a triangular expansion behm
