head with opercular apparatus considerably exceeding the maximum 
depth of the trunk, and nearly one quarter of the total length of the 
fish to the base of the caudal fin. Vertebrse about 6S in total 
number. Pelvic fins inserted opposite the origin of the dorsal fin, 
which arises at the middle of the back and comprises 13 or 14 rays ;

The only known fossil examples of this species are contained in ^ 
concretionary nodules from Glacial Clay. In Greenland these 
nodules are split by the Eskimo along the plane of the contained fish 
and then used as scrapers.
