P. 1592. Anterior fragment of fish displaying broad, ornamented 
dorsal ridge-scales, each apparently the result of the fusion 
of about three pairs of scales with the median one ; Lyme 
Begis (?). Egerton Coll. 
P. 515. Fragment of squamation labelled Dapedius micans by 
Agassiz and intended to be the type specimen of that 
species, named in list in Poiss. Foss. vol. ii. pt. i. (1844), 
p. 304; Upper Lias, Whitby. The scales are abraded 
and exhibit slight transverse rugae. Egerton Coll. 
P. 1591. Fragment probably of the same species, showing scales 
and remains of highly-ornamented head-bones, on which 
the tubercles are considerably fused into rugae ; Whitby. 
Two imperfect large teeth seem to have been simply 
pointed. Egerton Coll. 
P. 3536. Fragment apparently of similar squamation, labelled 
Dapedius micans by Agassiz ; Whitby. Enniskillen Coll. 
P. 3543. Imperfect small trunk with part of the coarsely tubercu- 
lated opercular apparatus ; Upper Lias, Ilminster, Somer¬ 
setshire. The scales are nearly smooth, without tubercu- 
lations or posterior serrations. Enniskillen Coll.
