Genus NEORHOMBOLEPIS, A. S. Woodward. 
[Proc. Geol. Assoc, vol. x. 188S, p. 304.] 
Trunk elongate-fusiform, and head relatively large. External 
head-bones and the opercular bones robust, more or less ornamented 
with tubercles and rugae of enamel; maxilla with a straight denti¬ 
gerous border, and a long supramaxillary bone ; teeth in regular 
series, large and hollow, nearly as large on some of the inner bones 
as on the margin of the jaw, but short and tubercular on the 
entopterygoid ; suboperculum at least half as large as the nearly 
rectangular operculum, and separated from the latter by an almost 
horizontally-extended suture. Vertebral centra completely ossified, 
much shorter than deep in the abdominal, more elongated in the 
caudal region. Pectoral fins relatively large, with an especially robust 
preaxial ray ; [other fins unknown]. Scales thick, with a narrow 
overlapped border not produced at the angles, and the peg-and-socket 
articulation feeble or wanting; superficial ganoine nearly smooth ; 
few principal flank-scales as deep as broad, the majority broader than 
deep, and those of numerous ventral series at least twice as broad 
as deep.

Type. Imperfect anterior portion of fish; British Museum. 
The type species, with head attaining a length of about 0*085. 
External bones ornamented with closely-arranged elongated 
tubercles and short rugae of ganoine ; marginal teeth slender, with 
incurved apex, in a close regular series, and those of the maxilla 
almost as large as those of the dentary. Preaxial pectoral fin-ray 
ornamented with elongated tubercles and rugae of ganoine. Large 
postclavicular scales ornamented as the head-bones, other scales 
smooth ; scales of the ventral abdominal region very much elon¬ 
gated, often nearly three times as broad as deep, and some with 
two or three coarse denticulations on the hinder margin.
