. Bulletin of the British Museum (Natural History), Geology. 7S CRETACEOUS FISHES FROM THE LEBANON lateral face of the distal ceratohyal, and two articulating the lateral face of the proximal ceratohyal. Vertebral column. There are 23 vertebrae, 9 abdominal and 14 caudal, including one free ural centrum (the second). Ribs are present on all the abdominal vertebrae except the first, and are borne on transverse processes on the last four (five in 101997). There are no epineurals or epipleurals. The caudal skeleton will not be described in detail here since I am dealing with the caudal skeletons

Bulletin of the British Museum (Natural History), Geology. 7S CRETACEOUS FISHES FROM THE LEBANON lateral face of the distal ceratohyal, and two articulating the lateral face of the proximal ceratohyal. Vertebral column. There are 23 vertebrae, 9 abdominal and 14 caudal, including one free ural centrum (the second). Ribs are present on all the abdominal vertebrae except the first, and are borne on transverse processes on the last four (five in 101997). There are no epineurals or epipleurals. The caudal skeleton will not be described in detail here since I am dealing with the caudal skeletons of all Cretaceous Beryciformes in a forthcoming paper : suffice it to say that the caudal of Lissoberyx agrees with that of the living trachichthyid Hoplostethus (Gosline, 1961 : 14) in having a neural crest on the second pre-ural centrum and a free second ural centrum. Pectoral and pelvic girdles and fins. The pectoral girdle contains the normal complement of bones, a curved extrascapular (ext.) articulating with the parietal. Fig. 3. Lissoberyx dayi (Smith Woodward). Restoration of the skeleton, scales omitted, X2-5 approx. above and the pterotic below, a forked suprascapular (ssc.) articulating with the epiotic and intercalar, a blade-shaped supracleithrum (scl.), a large, sigmoid cleithrum (cl.), two post-cleithra, the upper (d. pc.) scale-like, the lower (v. pc.) rod-like, and the scapula and coracoid. All the dermal bones of the girdle are smooth and un- ornamented. The anterior process of the coracoid {cor.) is moderately stout and long, arching forwards to join the cleithrum just above its tip. The pectoral fin contains about ten rays. The pelvic fins are thoracic, the fin originating well in front of the tip of the ventral post-cleithrum and the girdle {p. g.) ending between the anterior processes of the coracoids. The pelvic fin contains a stout, smooth spine and six soft rays. Median fins. The dorsal fin originates above the pelvic and occupies little more than half
