Type. Nearly complete fish ; Palaeontological Museum, Munich. 
A small species attaining a length of about 0*3. Length of head 
with opercular apparatus considerably exceeding the maximum 
depth of the trunk, and somewhat less than one-quarter of the 
total length of the fish. Caudal region little tapering, the depth of 
the caudal pedicle equalling about one-half the maximum depth of 
the trunk. Teeth large, with slender apex, and irregularly spaced. 
Dorsal fin with about 18 rays, deeper than long, its depth equalling 
at least three-quarters that of the trunk at its origin ; all the fins 
situated as in the type species. Scales smooth. 
According to Wagner (loc. cit. p. 706), the imperfectly described 
Caturus gramdatus , Miiuster (Neues Jahrb. 1842, p. 44), is closely 
related to this species.
