P. 6364. The type specimen, a waterworn piece of sandstone with 
imperfect coiled-up fish; Wealden, Hastings. The fish is 
partly exposed on both sides of the slab, and portions of 
its pectoral fin, squamation, and vertebral centra are 
shown of the natural size in PI. VIII. figs. 5, 5 a, b. The 
head and opercular apparatus are too imperfect for 
description, but traces of the characteristic external orna¬ 
ment are preserved both on the cranial roof and on the 
cheek-plates. The middle of the parasphenoid exhibits a 
cluster of small teeth ; and its lateral ascending portion is 
forked, the anterior limb rising as usual to meet the post¬ 
frontal, the posterior limb reaching one of the hinder otic 
elements. A horizontal (not median) section across one 
of the short abdominal vertebrae is shown in fig. 5 a ; 
and one of the three elongated centra, as exposed in the 
anterior part of the caudal region, is shown in side view 
in fig. 5 b. The latter are followed by other centra not 
so much elongated, but still longer than deep. The 
clavicle and pectoral fin are preserved on the left side, 
the latter comprising not less than 2 4 rays, of which each 
is undivided in its proximal two-thirds but becomes very 
finely branched and articulated distally. A portion of 
the largest postclavicular plate on the same side ( p.el .) 
displays the characteristic external ornamentation. The 
scales are all remarkably smooth, exhibiting no markings 
beyond feeble, scattered pits ; and the serration of their 
hinder border is extremely fine and inconspicuous. Even 
the principal flank-scales are broader than deep, while the 
ventral scales are not onlv extremelv narrowed but also 
«/ * 
become in part subdivided. Becleles Coll.

Type. Detached scales ; British Museum. 
A species known only from detached scales, and doubtfully placed 
in Neorhombolepis. The largest known scale measures 0*015 in 
breadth, and none are so deep as broad ; all specimens exhibit a 
smooth external layer of ganoine, marked with a few punctations,
