100 UPPER CRETACEOUS TELEOSTS 
HoLotypPEe. Specimen number 639/58 in the Museum d’Histoire Naturelle, 
Geneva, from the Middle Cenomanian of Hakel, Lebanon, a head with the precaudal 
region. 
MATERIAL. The holotype in Geneva and fifteen specimens in the B.M.N.H. The 
specimens used by Pictet (1850) and Pictet & Humbert (1866) were also examined 
in Geneva. All of the material examined was from the two Middle Cenomanian 
localities in the Lebanon, Hakel and Hajula. 
Remarks. All of the B.M.N.H. specimens were prepared in acetic acid by the 
transfer method. The only part of the skeleton which remains incompletely 
described is the neurocranium. All of the specimens of Eurypholis recovered from 
the Lebanese deposits are referable to the type species, being identical in body 
proportions and fin ray counts. The only variable feature in the osteology is the 
vertebral number, but this variation is within very narrow limits and the variability 
is confined to the precaudal region, the caudal region remaining constant at 20 
vertebrae. 
The references in the synonymy which occur after Igor are simply mentions of the 
specific name together with the reproduction of Woodward’s reconstruction of the 
body (1901 : text-fig. 7). 
DeEscRIPTION. Neurocranium. The neurocranium is shown in dorsal view in 
Text-figure 44. The cranial roof is flattened and widest at the hind border of the 
orbit between the sphenotics, and almost entirely composed of the frontals which 
extend back to near the occipital border. There is a straight suture between the 
frontals and a shallow median depression between the orbits which is more sparsely 
ornamented than the remainder of the skull-roof. The frontal extends on to the 
dorso-medial surface of the sphenotic, and the sphenotic just projects laterally from 
under it. The roof is covered by an ornamentation of raised bony tubercles 
radiating in all directions. Above the orbit and along the course of the supra- 
orbital sensory canal the tubercles are present on raised ridges of bone. Anteriorly 
the frontal tapers to end by insertion into (or under) the rear edge of the short, 
broad mesethmoid. 
The supraoccipital is small, meeting the frontals anteriorly and separating the 
parietals laterally. In the mid-line the supraoccipital bears a small backwardly 
directed crest which does not extend dorsally above the plane of the skull-roof. 
The parietals are transversally orientated, relatively narrow strips of bone bordered 
anteriorly by the frontals and laterally by the pterotics. Both the parietals and the 
supraoccipital are in part covered by the backward extension of the frontals. The 
tubercular ornamentation of the frontals is continued on the parietals and the supra- 
occipital. Near the posterior edge of the parietal a low transverse crest is present 
which functioned as an area for muscle insertion. The narrow strip of parietal and 
that portion of epiotic which is visible behind the crest are devoid of ornamentation. 
The pterotic forms the postero-lateral border of the skull-roof, contacting the 
sphenotic anteriorly and the frontal and parietal medially. The dorsal surface of 
the pterotic is ornamented with tubercles which are connected by ridges of bone
