1881. Pholidophorus magnus , B. Vetter, Mittheil. k. mineral.-geol. Mus. 
Dresden, pt. iv. p. 68. [A new collective name given to the species 
to which the above synonymy applies.] 
1887. Pholidophorus striola?'is, K. A. yon Zittel, Handb. Palseont. 
yol. iii. p. 214, figs. 226, 227. 
Type. Imperfect fish with scattered squamation ; Palaeontological 
Museum, Munich. 
A large robust species, attaining a length of about 04. Length 
of head with opercular apparatus somewhat less than the maximum 
depth of the trunk, which equals about one-quarter of the total 
length of the fish. Head and opercular bones very finely rugose ; 
maxilla very conspicuously ornamented, the rugae chiefly longitudinal 
and in part reticulated ; angle of preoperculum with feeble radiating 
ridges; teeth comparatively robust, obtusely pointed. Fin-rays 
very stout, smooth or delicately rugose ; fulcra conspicuous. Pelvic 
fins arising far in advance of the middle point of the trunk, and the 
dorsal fin opposed to them. Scales large, ornamented with fine 
oblique striations, more or less radiating, and terminating at the 
hinder margin in prominent denticulations ; several series of flank- 
scales deeper than broad ; the orifices of the lateral line incon¬ 
spicuous, and the ornament on the caudal region becoming feeble. 
The synonymy of this species is given in accordance with the 
researches of Wagner and Vetter. Very probably there must also 
be added to it the name of Pholidophorus microps, given to a 
small fish from Solenhofen in the Palaeontological Museum, Munich 
(L. Agassiz, Poiss. Foss. vol. ii. pt. i. 1833-44, pp. 9, 275, pi. xxxviii.

1863, p. 666; B. Vetter, Mittheil. k. mineral.-geol. Mus. Dresden,

Form. Sf Loc. Lower Kimmeridgian (Lithographic Stone): Bavaria. 
P. 5542. Fine specimen, about 0‘39 in length, perhaps a little 
elongated by distortion ; Eichstadt. Part of the axial 
skeleton of the trunk is displayed and coprolitic matter 
indicates the remote situation of the anus.
