Trying to ID this fish from the Sannine in Lebanon and having a bit of trouble. About 13cms in length. The dorsal fin seems like a good hint, but haven't found a match for it yet. Anyone got any ideas?

The transcription of the Arabic terms and names is often ambiguous. In the literature the locality is called Hakel, Hâkel, Hackel, Haquil or Haquel. Taxonomy from GBIF.org. Alternative combination: Beryx vexillifer Pictet 1850. Diagnosis for the genus Ctenothrissa from Woodward 1899, p. 490: "Head large; trunk deeply fusiform and laterally compressed, but ventral border of abdomen flattened. Maxilla robust and arched, with two large supramaxillary bones; mandible deep, a little prominent, and gape of mouth not extending behind the middle of the large orbit; minute teeth on the margin of the jaws. Preoperculum only slightly expanded; operculum and suboperculum, deep and narrow. Vertebrae from 30 to 40 in number, half being caudal. Pe]vic fins much enlarged and inserted far forwards; dorsal fin much deepened, occupying about half of the back; anal fin small; caudal fin deeply cleft. Scales pectinated, large and regularly arranged, none enlarged or thickened, and no dorsal or ventral ridge-scales ; lateral line conspicuous." References: Woodward, A. S., (1899): Note on some Cretaceous clupeoid fishes with pectinated scales (Ctenothrissa and Pseudoberyx). Annals and Magazine of Natural History, series 7 3:489-492. Woodward, A.

Characteristic for Eurypholis (meaning "broad scale") are the three large scales directly behind the head. References: A. S.
