86 UPPER CRETACEOUS TELEOSTS 
arising behind the dorsal, nearer to the caudal than to the pelvics. Thirty-seven 
vertebrae of which 24 are caudal. 
HoLotypPe. Once in the Museo Civico di Storia Naturale, Trieste, present loca- 
tion unknown. The holotype was from the Middle Cenomanian of Hakel, Lebanon. 
MATERIAL. Specimens in the B.M.N.H., numbers P.4748, P.g250, P.47316, from 
the Middle Cenomanian of Hakel and all prepared by the transfer method in acetic 
acid. 
REMARKS. The species is known solely by flattened specimens from Hakel and 
Hajula in the Lebanon. Woodward (1901 : 200) noted this species and stated that 
it was not clearly distinguishable from Enchodus longidens. Hay (1903 : 421) 
separated Enchodus marchesettit as a distinct species. The neurocranium was not 
clearly observable in the specimens examined, but it does not appear to have 
differed to any noticeable extent from that of Enchodus lewesiensis, or that of 
Enchodus faujasi (Goody, 1968). Arambourg (1952 : 232, fig. 50) shows a photo- 
graph of the caudal skeleton and compares it with that of Enchodus libycus Quaas 
in which he indicates two large plate-like hypurals. This comparison of the two tail 
skeletons is open to some doubt when compared with the description and figure of 
the caudal skeleton presented below. 
DEscRIPTION. Neurocranium. The frontals are visible merging anteriorly with 
the mesethmoid. Immediately posterior to this the lateral edge of the frontal bears 
a large elongated pore which is the anterior opening of the tube which in life con- 
tained the supraorbital sensory canal. The lateral region of the frontal is visible 
above the orbit and bears an ornamentation of tuberculated ridges. Above the 
sphenotic immediately posterior to the hind end of the orbit the postero-lateral 
region of the frontal is indented, indicating the anterior demarcation of the forward 
extent of the unroofed post-temporal fossa. This indentation is only in the upper 
ornamented layer of the frontal, since the frontal itself forms part of the floor of the 
anterior region of the fossa. The frontal overlaps part of the dorsal surface of the 
sphenotic. 
The cranium is relatively deep in the posterior region but becomes shallower 
anteriorly. The orbit is very large, occupying about half the length of the neuro- 
cranium, while the cranial cavity itself is rather small. The frontal meets the 
parietal posteriorly in the medial wall of the post-temporal fossa. Immediately 
behind the parietal there is a rounded knob of bone which may have been separated 
partially from the parietal by a groove, this is the epiotic forming the occipital 
border of the skull-roof. The crest on the pterotic can be seen crushed slightly into 
the post-temporal fossa. This crest forms the lateral wall of the fossa, as well as the 
medial demarcation of the dilatator fossa. The suture between the sphenotic and 
pterotic is visible within the fossa. At the posterior end of the pterotic crest there is 
some evidence of a pore leading into a tube within the crest which transmitted the 
otic branch of the infraorbital sensory canal. The upper boundary of the hyo- 
mandibular facet, formed of pterotic and sphenotic, is visible below the dilatator 
fossa. The sphenotic forms the upper posterior limit of the orbit and extends
